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.

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 (

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.

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.
