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.
Horizontal mounting position (normal mounting
position)
Mount the power supply unit in the standard installation
position. Position of the L/N connection terminal blocks
at bottom.
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).
The power supply is approved for the connection to TN,
TT and IT power grids (star networks) with a maximum
phase-to-phase voltage of 240 V AC
Protect the device against foreign bodies penetrating it,
e.g., paper clips or metal parts.
The power supply is maintenance-free. Repairs may
only be carried out by the manufacturer. The warranty
no longer applies if the housing is opened.
The power supply may only be used for its intended use.

High-voltage test (HIPOT)
This protection class I 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.
High-voltage tests can be performed as
described.
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).
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.

High-voltage dielectric test (dielectric strength
test)

UNO2 POWER Ord.No. 2910105
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 AC input

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 2.2 kV AC or higher. Routine manufacturing tests are
inspected regularly by a certification authority.
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.

To ensure sufficient convection, a minimum clearance is
necessary between the power supply and above/below the

on the standard mounting position with nominal power

Installation height
You can operate the power supply without power limitations
up to an installation altitude of 2000 m. For altitudes higher
than 2000 m, different specifications apply due to the
differing air pressure and the reduced convection cooling
associated with this (see section: Derating).

Mounting the power supply unit
Proceed as follows to mount the power supply:
1. In the standard mounting position, the power supply is
mounted on the DIN rail from above. When doing so,
ensure that the snap-on foot engages correctly behind
the DIN rail (A).
2. Then press the power supply down until the snap-on
foot audibly latches into place (B).
3. Check that the power supply is securely attached to the
DIN rail.

Device connection terminal blocks
The AC input, DC output, and signal 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
AC input terminal blocks
The power supply is designed such that it can be operated
on single-phase AC supply systems or on two phase
conductors of three-phase systems. Here, the star supply
system supports various supply system configurations,
for example TT, TN, and IT systems.

Protection of the primary side
The installation of the power supply must conform to the
regulations of EN 61010. It must be possible to switch the
power supply off using a suitable disconnection device
outside of the power supply. The line protection on the
primary side is suitable for this (see section: Technical data).

DC output terminal blocks
Connect the DC load to be supplied to the Output DC
connection terminal blocks (connection level 2.x, output). By
default, the power supply is preset to a nominal output
voltage of 24 V DC. To compensate for a line-related
voltage drop over long distances between the power supply
and the DC load, you can adjust the DC output voltage using
the potentiometer (see section: Potentiometer).
9.4.2
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.
9.5
Connection terminal blocks, floating switch
contact (13/14)
There is a floating switch contact on the Output DC
connection terminal blocks (connection level 3.x, signal) for

13.3
Position-dependent derating
In order that you can use the nominal power of the power supply without limitation, the power supply should always be
mounted in the standard mounting position. Sufficient device-side convection is always assured if the power supply is
mounted in the standard mounting position and the necessary restricted areas are observed.
NOTE: Damage due to thermal overload
If the supply is mounted in a different mounting position, only a reduced amount of power can be drawn.
Otherwise, the power supply will be thermally loaded disproportionately and the device service life significantly
reduced.
