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 impair safety and
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
VDE01000 and EN50178.
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
" " 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.

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 connect/disconnect plug connectors
when the power is off!

Convection cooling (See Fig. 1)

Do not cover any ventilation holes!
Leave sufficient space around the unit for cooling!

Warning: High voltage! Stored 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 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
Mounting (See Fig. 1)

Permissible mounting position: keep free ventilation hole,
leave space for cooling! Recommended to have 25mm
free space at all sides for ventilation / cooling.

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.

Front elements
Operation indicator

Indicates whether the unit is working properly. Green LED is
lit if the voltage at the output terminal is more than 75%.

DC output low indicator

Red LED is lit when the voltage at the output terminal is 70%
to 90% of the rated output voltage.

Potentiometer

Used to set the output voltage.

All specifications are typical at norminal line, full load,

Connection / Internal fuse

Connection (See Fig. 3)

Data for permitted loads, cable cross-sections and stripping.
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 is connected to
the non-fused earth conductor.

-

Secondary side is not earthed; if necessary the or

+

terminal can be earthed optionally.

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.
