Note
1. Power supply components may degrade, or
be damaged, when the power supply is
continuously used outside the shaded region,
refer to the graph shown in Fig. 1.
2. If the output capacity is not reduced when the
surrounding air temperature
exceeds its
specification as defined on Page 3 under
“Environment”, the device will run into Over
Temperature Protection. When activated, the
output voltage will go into bouncing mode and
will recover when the surrounding air
temperature is lowered or the load is reduced
as far as necessary to keep the device in
working condition.
3. In order for the device to function in the
manner intended, it is also necessary to keep
a safety distance as recommended in the
safety instructions while the device is in
operation.
4. Depending on the surrounding air temperature
and output load delivered by the power
supply, the device can be very hot!
5. If the device has to be mounted in any other
orientation, please contact [e-mail]
for more details.

Assembly & Installation
The power supply unit (PSU) can be mounted on 35 mm DIN rails in accordance with EN 60715. The device should be installed with
input terminal block at the bottom.
Each device is delivered ready to install.
1. Tilt the unit upwards and insert it onto the DIN rail. Snap on the DIN rail as shown in Fig. 3.1.
2. Push downwards until stopped.
3. Press against the bottom front side for locking.
4. Shake the unit slightly to ensure that it is secured.
5. To uninstall, pull or slide down the latch with screw driver as shown in Fig. 3.2. Then slide the power supply unit (PSU) in the opposite
direction, release the latch and pull out the power supply unit (PSU) from the rail.
Mounting Dismounting
Fig. 3.1 Mounting Fig. 3.2 Dismounting
In accordance to IEC/EN/UL/CSA 62368-1 and IEC/EN/UL/CSA 61010-2-201, flexible cables require ferrules.
Use appropriate copper cables designed to sustain operating temperature of:
•At least 75°C for ambient < 40°C
•At least 90°C for ambient < 70°C.

Safety Instructions
Vertical Mounting
•ALWAYS switch mains of input power OFF before connecting and disconnecting the input voltage to the unit. If mains are not turned
OFF, there is risk of explosion / severe damage.
•To guarantee sufficient convection cooling, please refer to the following instructions to ensure sufficient clearance around
the device.
Vertical Mounting: 80 mm (3.15 inch) above and 40 mm (1.57 inch) below the device as well as a lateral distance of 5 mm
(0.20 inch) to other units. In case the adjacent device is a heat source (50% load of 240 W), the lateral distance will be 25
mm (0.98 inch).
Horizontal Mounting: 80 mm (3.15 inch) above and 40 mm (1.57 inch) below the device as well as a lateral distance of 40 mm
(1.57 inch) to other units.
•The external enclosure where the unit will be installed shall meet the requirements for mechanical, electrical and fire enclosure.
•Note that the enclosure of the device can become very hot depending on the surrounding air temperature and load of the power
supply. Risk of burns!
•The main power must be turned off before connecting or disconnecting wires to the terminals.
•DO NOT insert any objects into the unit.
•Hazardous voltages may be present for up to 5 minutes after the input mains voltage is disconnected. Do not touch the unit during
this time.
•The power supplies are built in units and must be installed in a cabinet or room (condensation free environment and indoor location)
that is relatively free of conductive contaminants.
•The power supply is approved for the connection to 3-phase TN, TT and IT power grids (star networks) with a maximum phase-to-
phase voltage of 500 Vac.
Horizontal Mounting
