Please note:

l

The user should ensure that the cable cross sections of the relevant

load circuit are suitable for the current rating of the ESS22-T used.

l

Automatic start-up of machinery after shut down must be prevented

(Machinery Directive 98/37/EG and EN 60204-1). In the event of a

short circuit or overload the ESS22-T ensures double pole physical

isolation of the load circuit.

Without this current limitation a considerably higher overload
