5.1.1 Protection of persons

 Danger!

ƒ Before working on the regenerative power supply module, check that no

voltage is applied to the power terminals.

– Some power terminals remain live for at least three minutes after mains

disconnection.

ƒ For controllers in DC−bus operation

– the controller must be inhibited.

– the controller must be separated from the mains.

ƒ The discharge current to PE is > 3.5 mA; i.e. a fixed installation is required

and PE must be connected according to EN 61800−5−1.

Earth−leakage circuit breaker

We recommend e.l.c.b.s to protect persons and animals ( 104).

Pluggable terminal strips

All pluggable terminals must only be plugged on or removed when no voltage is applied!

Disconnecting the controller from the mains

Make a safety connection between the controller and mains only via a contactor at the

input side.
