operation may be reduced. The specified service life of more than 15 years is simply a comparative value.

Mounting/removing the power
supply
8.1
Mounting the power supply unit
Proceed as follows to mount the power supply:
1. The power supply is mounted in the normal mounting
position from above onto the 35 mm DIN rail (DIN EN
60715). Make sure that the integrated snap-on foot is in
the correction position behind the DIN rail (A).
2. Then press the power supply down until the integrated
snap-on foot audibly latches into place (B).
3. Check that the power supply is securely attached to the
DIN rail.

1. Take a suitable screwdriver and insert this into the lock
hole on the integrated snap-on foot (A).
2. Release the lock by lifting the screwdriver (B).
3. Carefully swivel the power supply forward (C) so that
the lock slides back into the starting position.
4. Then separate the power supply from the DIN rail (D).

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 PKB 140X3,6 - Order No. 1005460).
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
The AC input and DC output terminal blocks on the front of
the power supply feature screw connection technology.
For the necessary connection parameters for
the connection terminal blocks, refer to the
technical data section.
9.1
9.2
Protection of the primary side
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).
DANGER: Hazardous voltage
An all-pos. fuse must be present for operation
on three-phase and DC systems.
Input
The power supply is operated on single-phase AC systems
or two outer conductors of three-phase systems. The power
supply is connected on the primary side via the INPUT L/N
connection terminal blocks.

Output
By default, the power supply is pre-set to a nominal output
voltage of 24 V DC.
The output voltage is adjusted using the potentiometer.
9.4
Protection of the secondary side
The power supply is electronically short-circuit-proof and
no-load-proof. In the event of an error, the output voltage is
limited
If sufficiently long connecting cables are used,
fuse protection does not have to be provided
for each individual load.
If each load is protected separately with its
own protective device, the selective shutdown
in the event of a fault enables the system to
remain operational.

Output characteristic curves
UOut [V]
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 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.

Location and function of the signaling elements
For signaling and the functional monitoring of the power
supply two LEDs and an active signal output are available.
Using the rotary selector select the required functional
monitoring. The monitoring of the output voltage (DC OK) or
the exceedance of the output power threshold are available
(POut > PThr).

Rotary selector switch in position DC OK:
In this switch position the output voltage (UOut) is monitored.
If the DC OK threshold is exceeded (UOut > 0.9 x USet) the
green DC OK LED turns on. Additionally, the signal output
(SIG) "active high" is active. If the output voltage drops
below the DC OK threshold value (UOut 50 %, >75 %
or boost >100 %:
In each of these switch positions the output power (POut) is
monitored. When the set threshold is exceeded the yellow
LED lights up (POut > PThr) and the signal output (SIG)
switches to "active low".

Operating modes
Depending on the intended use, the power supply can be
run in series or parallel operation.
13.1
You can connect several power supplies in parallel in order
to increase the power or to supply the loads redundantly.
IN
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 24 V DC
power supplies are connected in series, an output voltage of
48 V DC is available to supply the loads.

Schematic diagrams in series operation
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
environment
6. When three or more power supplies are connected in
parallel, each output must be protected (e.g., with
circuit breakers or decoupling modules)

13.2.1 Redundancy operation
13.2.2 Increased power
Redundant circuits are suitable for supplying systems and
system parts which place particularly high demands on
operational reliability.
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.
If energy 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
mode, two 3.8 A power supplies supply a load with a
nominal current of 3.8 A, for example. During normal
operation of the power supplies, each power supply
therefore supplies 1.9 A.
When three or more power supplies are
connected in parallel, each output must be
protected separately, e.g., by a circuit breaker
or decoupling module such as UNO DIODE or
STEP DIODE.
Always use cables with the same cross sections and lengths
when wiring the power supplies on the DC output side.
A redundancy module can be used to 100% decouple two
power supplies from one another and to ensure the supply.
A distinction is made here between passive and active
redundancy modules. Optimum decoupling with
simultaneous monitoring and minimal power dissipation can
be achieved with the UNO DIODE redundancy module.

Schematic diagram, redundant operation with
diode
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.
The following conditions must be met for 1+1 and n+1
redundancy operation of the power supplies in conjunction
with a UNO DIODE redundancy module.
Only use power supplies with the same performance class
and configuration for parallel connection.
Using the signaling settings, you can monitor whether both
power supplies are being operated with ≤ half the nominal
load. In the case of system extension, an overload is
prevented if one of the power supplies fails.

Derating
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
POut [W]
When operating the power supply at an ambient
temperature of > 60 °C, a power derating of 2.5 %/K should
be observed. In the temperature range up to 60 °C, the
power supply can output up to 200 % of the nominal output
power PDyn.Boost for a maximum of 5 s.

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.
