Safety notes
Read Instructions!
Before working with this unit, read these instructions carefully and
completely. Make sure that you have understood all the information!
Disconnect system from supply network
Before any installation, maintenance or modification work:
Disconnect your system from the supply network. Ensure that it cannot be re-
connected inadvertently!
Before start of operation
Ensure appropriate installation
Warning! Improper installation / operation may impair safety and may result in
operational difficulties or complete failure of the unit. The unit must be
installed and put into service appropriately by qualified personnel.
Compliance with the relevant regulations must be ensured. Before operation is
begun the following conditions must be ensured, in particular: Connection to
main power supply in compliance with: see Approvals and Standards. With
stranded wires: all strands must be secured in the terminal blocks (potential
danger of short circuit). Unit and power supply cables must be properly fused;
if necessary a manually controlled disconnecting element must be used to
disengage from supply mains. The non-fused earth conductor must be connected
to the ground terminal (protection class 1). All output lines must be rated
for the power supply output current and must be connected with the correct
polarity. Sufficient air- cooling must be ensured. Use in a pollution degree 2
environment.
In operation: No modifications!
As long as the unit is in operation: do not modify the installation! The same
applies also to the secondary side. Risk of electric arcs and electric shock
(fatal)! Only (dis) connect plug connectors when the power is off!
Convection cooling
Do not cover any ventilation holes!
Leave sufficient space around the unit for cooling!
See supplementary sheet “Technical Data” and Fig. 1
Warning: High voltage! Store energy!
The unit contains unprotected conductors carrying a lethal high voltage, and
components storing substantial amounts of energy. Improper handling may result
in an electric shock or serious burn! The unit must not be opened except by
appropriately trained personnel! Do not introduce any object into the unit!
Keep away from fire and water!
Installation
Application
This unit is a primary switched-mode power supply designed for use in panel-
board installations or building-in applications where access to the supply is
restricted (shock-hazard protection). It must only be installed and put into
service appropriately by qualified personnel.
Mounting
Permissible mounting position: see Fig. 1 keep free ventilation hole, leave space for cooling! Recommended to have 25mm free space at all sides for ventilation / cooling: see supplementary sheet “Technical Data”. Snap on support rail (See Fig. 2)
- Tilt the unit slightly rearwards.
- Fit the unit over top hat rail.
- Slide it downward until it hits the stop.
- Press against the bottom front side for locking.
- Shake the unit slightly to check the locking action.

Connection/Internal fuse
Connection
- Data for permitted loads, cable cross-sections and stripping: see enclosed leaflet “ Technical Data “ (See Fig. 3).
- Use only commercial cables designed for the indicated voltage and current values!
- With flexible cables: make sure that all stranded cable are secured in the terminal.
- Ensure proper polarity at output terminals!
Grounding
- Do not operate without PE connection! To comply with EMC and safety standards (CE mark, approvals), the unit must only be operated if the PE terminal ground is connected to the non-fused earth conductor.
- Secondary side is not earthed; if necessary the – terminal can be earthed.
Internal fuse
The internal input fuse serves to protect the unit and must not be replaced by
the user. In case of an internal defect, the unit must be returned to the
manufacturer for safety reasons.
Removal
Removal from DIN Rail
Insert a flat screwdriver into the slot in the clamp. Pull down the clamp out
unit the clamp clicks, and turn the switching power supply bottom out. (See
Fig. 4)
