Only skilled persons may install, start up, and operate
the device.
Never carry out work when voltage is present.
Establish connection correctly and ensure protection
against electric shock.
Cover termination area after installation in order to avoid
accidental contact with live parts (e. g., installation in
control cabinet).
Observe the national safety and accident prevention
regulations.
Assembly and electrical installation must correspond to
the state of the art.
The power supply is a built-in device and is designed for
mounting in a control cabinet.
The IP20 degree of protection of the device is intended
for use in a clean and dry environment.
Observe mechanical and thermal limits.
Ensure that the primary-side wiring and secondary-side
wiring are the correct size and have sufficient fuse
protection.
For the connection parameters for wiring the power
supply, such as the required stripping length with and
without ferrule, refer to the technical data section.
Use copper cables for operating temperatures of
75 °C (ambient temperature 55 °C)
90 °C (ambient temperature 75 °C).
Protect the device against foreign bodies penetrating it,
e.g., paper clips or metal parts.

NOTE: Damage to the Push-in connection
terminal blocks is possible
Do not plug test pins into the Push-in connection
terminal blocks. The maximum pluggable depth of
the Push-in connection terminal blocks is limited.
In addition, when the test pin is plugged in, the
unlocking button (pusher) is covered to such an
extent that unlocking is not possible or only
possible to an insufficient extent. If you do not
push the unlocking button (pusher) down
completely when you are pulling the test pin out,
then the Push-in connection terminal block will
become damaged.

High-voltage test (HIPOT)
This protection class II power supply is subject to the Low
Voltage Directive and is factory tested. During the HIPOT
test (high-voltage test), the insulation between the input
circuit and output circuit is tested for the prescribed electric
strength values, for example. The test voltage in the highvoltage range is applied at the input and output terminal
blocks of the power supply. The operating voltage used in
normal operation is a lot lower than the test voltage used.
6.3
High-voltage dielectric test performed by the
customer
Apart from routine and type tests to guarantee electrical
safety, the end user does not have to perform another highvoltage test on the power supply as an individual
component. According to EN 60204-1 (Safety of machinery
- Electrical equipment of machines) the power supply can be
disconnected during the high-voltage test and only installed
once the high-voltage test has been completed.
High-voltage tests up to 1.2 kV DC can be
performed as described.
The test voltage should rise and fall in ramp form.
The relevant rise and fall time of the ramp should
be at least two seconds.
6.1
High-voltage dielectric test (dielectric strength
test)
In order to protect the user, power supplies (as electric
components with a direct connection to potentially
hazardous voltages) are subject to more stringent safety
requirements. For this reason, permanent safe electrical
isolation between the hazardous input voltage and the
touch-proof output voltage as safety extra-low voltage
(SELV) must always be ensured.
In order to ensure permanent safe isolation of the DC input
circuit and DC output circuit, high-voltage testing is
performed as part of the safety approval process (type test)
and manufacturing (routine test).
6.2
High-voltage dielectric test during the
manufacturing process
During the power supply manufacturing process, a highvoltage test is performed as part of the dielectric test in
accordance with the specifications of IEC/UL/EN 61010-1.
The high-voltage test is performed with a test voltage of at
least 1.2 kV DC or higher. Routine manufacturing tests are
inspected regularly by a certification authority.

6.3.1
Performing high-voltage testing
If high-voltage testing of the control cabinet or the power
supply as a stand-alone component is planned during final
inspection and testing, the following features must be
observed.
– The power supply wiring must be implemented as
shown in the wiring diagram.
– The maximum permissible test voltages must not be
exceeded.
Avoid unnecessary loading or damage to the power supply
due to excessive test voltages.
For the relevant applicable test voltages and
insulation distances, refer to the corresponding
table (see technical data: electric strength of the
insulation section).

Fix connection wiring to the power supply
Two receptacles for the bundled attachment of the
connection wiring are integrated in the left and right housing
panel. Use cable binders to secure the connection wiring
(optional WT-HF 3,6X140 - Item No. 3240744).
Proceed as follows to secure the connection wiring:
– Wire the power supply with sufficient connection
reserve (input terminal blocks, output terminal blocks,
signal terminal block)
– Bundle and set up the connection wiring so that the
ventilation slits on the top and bottom of the housing are
covered as little as possible.
– Thread the cable binders into the necessary
receptacles for the cable binders.

Device connection terminal blocks
If sufficiently long connecting cables are used,
fuse protection does not have to be provided for
each individual load.
The front-mounted DC input and DC output terminal blocks
and the signal terminal blocks of the power supply feature
Push-in connection technology. The wiring is performed by
plugging in, without tools.
For the necessary connection parameters for the
connection terminal blocks, refer to the technical
data section.

Protection of the primary side
The power supply is connected on the primary side via the
Input +/- connection terminal blocks.
Installation of the device must correspond to EN 61010
regulations. It must be possible to switch off the device using
a suitable disconnecting device outside the power supply.
The line protection on the primary side is suitable for this
(see technical data section).

Output characteristic curves
The U/I output characteristic curve is optimized for the
following applications:
– When supplying loads with high switch-on currents,
such as motors. The dynamic boost of the power supply
supplies up to 200% of the nominal power for 5 s. This
ensures that sufficient reserve energy is available;
overdimensioning of the power supply is not necessary.
– For system extension. With the static boost, up to
125% of the nominal output power is available for a
sustained period (up to 40°C).
– For fast energy storage charging (e.g., of batteries) to
supply a wide range of loads. The power supply
operates in the nominal operating range. Energy supply
to the load is ensured.

The power supply provides the static boost (IStat. Boost) for a
sustained load supply or the time-limited dynamic boost
(IDyn. Boost).
11.1
Static Boost
Use the following tables to determine the required recovery
time (tPause) at the maximum dynamic boost current (IDyn.
Boost) based on the following values:
– IBase Load
– Duration of the boost current (tDyn. Boost)
– Ambient temperature (40 °C or 60 °C)
For system expansion purposes, the sustained static boost
(IStat. Boost) supports the load supply with up to 125 % of the
nominal current of the power supply. The static boost is
available at an ambient temperature of up to 40 °C.

Operating modes
13.2.1 Redundancy operation
Depending on the intended use, the power supply can be
run in series or parallel operation.
13.1
Series operation
To double the output voltage, connect two power supplies in
series. Only use power supplies with the same performance
class and configuration for series operation. If two 48 V DC
power supplies are connected in series, an output voltage of
96 V DC is available to supply the loads.

-96 V
+

-48 V
If power is to be supplied to the load with 1+1 redundancy,
two power supplies of the same type and performance class
must be used. In the event of an error, it must be ensured
that one of the power supplies is able to provide the total
required power for the load. This means that in redundancy
operation, two 2 A power supplies supply a load with a
nominal current of 2 A, for example. During normal
operation of the power supplies, each power supply
therefore supplies 1 A.
Always use cables with the same cross sections and lengths
when wiring the power supplies on the DC output side.
+
+48 V
Redundant circuits are suitable for supplying systems and
system parts which place particularly high demands on
operational reliability.
QUINT POWER power supplies with integrated decoupling
MOSFET can be used for 1+1 and n+1 redundancies. The
power supplies are up to 100 % decoupled from each other.
They ensure the supply in case of error.

Observe the following points when carrying out parallel
connection:
1. Use power supplies of the same type and performance
class
2. Setting the same output voltages
3. Using the same cable cross sections for wiring
4. Using the same cable lengths for the DC convergence
point
5. Operating power supplies in the same temperature

Certain specifications apply in redundancy operation with
regard to the configuration of the keepout areas. In
redundancy operation, the power supplies are operated with
maximum half the nominal power. The keepout areas are
therefore reduced.
Using the signaling settings, you can monitor whether both
power supplies are being operated with the same nominal
load. In the case of system extension, an overload is
prevented if one of the power supplies fails.

When n power supplies are connected in parallel, the output
current is increased to n x IN. Parallel connection for
increased power is used when extending existing systems.
If the individual power supply does not cover the current
consumption of the most powerful load, parallel connection
of power supplies is recommended.

Derating
14.2
The QUINT POWER power supply runs in nominal
operation without any limitations. For operation outside the
nominal range, the following points should be observed
depending on the type of use.
14.1
Ambient temperature
When operating the power supply at an ambient
temperature of > 60 °C, a power derating of 2.5 %/K should
be observed. Up to an ambient temperature of 40 °C, the
power supply can take power from the static boost for a
sustained period. In the 40 °C to 60 °C temperature range,
the power supply can output more than the nominal power
for a sustained period.

Installation height
The power supply can be operated at an installation height
of up to 2000 m without any limitations. Different data
applies for installation locations above 2000 m due to the
differing air pressure and the reduced convection cooling
associated with this (see technical data section). The data
provided is based on the results of pressure chamber testing
performed by an accredited test laboratory.

Position-dependent derating
The fanless convection-cooled power supply can be snapped onto all DIN rails according to EN 60715.
The power supply should be mounted horizontally for heat dissipation reasons (input connection terminal blocks
facing downward). Please observe the derating for any mounting other than the normal mounting position. Reduce
the output power based on the prevailing ambient temperature.
The recommended output power for different mounting positions and ambient temperatures can be found in the
characteristic curves below.
Exceeding these values will reduce the service life of the power supply.
