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.
