Notes for installation
l The max. total current of 40A per way must not be exceeded
l The user has to ensure that the cable cross section of the load
circuit in question complies with the current rating of the used
load or circuit protector.
l The technical data of the circuit protector have to be observed.
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/EG and EN 60204-1, Safety of Machinery). In the event
of a failure (short circuit/overload) the load circuit will be discon-
nected by the circuit protector.
l The power distribution system must only be installed by qualified
personnel.
l It is only intended for use with safety extra-low voltage (= 24V DC).
l Only after expert installation must the device be supplied with
power.
l After tripping of the circuit protector, before reset, the cause of
6
short circuit or overload has to be remedied.
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 Connection to a higher or not reliably disconnected voltage can
cause hazardous conditions or damages.
