Notes for installation
The power distribution system must only be installed by qualified
personnel.
l
Only after expert installation must the device be supplied with
power.
l
The user has to ensure that the cable cross section complies with
the applicable current rating.
l
The national standards (e.g. for Germany DIN VDE 0100) have to
be observed for installation and selection of feed and return cables.
l
Recommended circuit breaker for the primary input cable protection:
E-T-A type 4230 IN max. 20 A
l
Recommended selective overcurrent protection for the secondary
output protection: E-T-A types ESS.., ESX.., und REF…
l
In addition special precautions must be taken in the system or
machine (e.g. use of a safety PLC) which reliably prevent an
automatic re-start of parts of the system (cf. Machinery Directive
2006/42/EU and EN 60204-1, Safety of Machinery). In the event of
a failure (short circuit/overload) the load circuit will be disconnected
by the circuit breaker/protector or the switched mode power supply.
