Notes

l

The user has to ensure that the cable cross section of the load

circuit in question complies with the current rating of the ESS30-S

used.

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 electronically with physical isolation of the contacts by the

ESS30-S.
