Safety notes
(Fig. 1)
Read
instructions!
Before working with this unit, read these instructions
carefully and completely. Make sure that you have
understood all the information (ask colleagues)! Comply
with notes on the unit!
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 result in operational difficulties or complete
failure of the unit.
The unit must be installed and put into service by appro-
priately qualified personnel. Compliance with the rele-
vant regulations (DIN, VDE or specific national
regulations) must be ensured. Before operation is
begun the following conditions must be ensured, in par-
ticular:
• Connection to mains supply in compliance with
VDE0100 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.
A disconnecting device has to be provided for the end
product to disengage unit and supply cables from
supply mains if required.
• 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 cor-
rect polarity.
• Sufficient air-cooling must be ensured.
In operation:
No modifica-
tions!
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
"
.
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 burns!
• The unit must not be opened except by appropriately
trained personnel!
• Do not introduce any objects into the unit!
• Do not open the unit for at least 5 minutes after it has
been disconnected from the mains on all poles!
• Keep away from fire and water!

Installation
Admissible area of
application
This unit is a primary switched-mode power supply unit
for use in
panel-board installations or other building-in applications
where
a suitable mechanical enclosure shall be provided to fulfill the require-
ments for shock-hazard protection and/or protection from hazardous
energy levels as well as for fire protection. It must only be installed
and put into service by appropriately qualified personnel.

Connection / Internal fuse
Connection
• Data for permitted loads, cable cross-sections and stripping as well
as for external fusing: see the enclosed leaflet "Technical Data",
sub heading "Connection to Mains" or "Output"
• Handling of the terminals: see Fig. 4
• Use only commercial cables designed for the indicated voltage and
current values!
• With flexible cables: make sure that all cable strands are secured in
the terminal.
• Suitable conductor terminal sleeves (ferrules) may be used.
• 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 protects 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
Detaching from the
support rail
Before removal:
Switch mains power off and disconnect your system
from the supply network.
See Fig. 6: push the slider downwards (unlock). Gently lift lower front
edge of the unit (tipping) and remove.
Recycling
The unit contains elements which are suitable for recycling, and
components which need specialist disposal. You are therefore
requested to make sure that the unit will be recycled by the end of its
service life.
Remarks:
d) See enclosed leaflet "Technical Data" sub-heading "Connection to Mains" or "Output" for
details.
e) unless there are other instructions either on the unit or in the enclosed leaflet "Technical
Data"
f) Not available with all units
This is a general information leaflet for all units in the current range. With some units devia-
tions from the instructions described here are possible,
therefore instructions in the
"Technical data" leaflet enclosed always take priority.
In case of doubt
the German version applies.
