Electrical isolation
6.1.1
Electrical isolation
The protective insulation of the "8400 Inverter Drives" controllers is implemented
according to EN 61800−5−1. The following illustration shows the insulation concept.

6.1.2
Device protection
In case of condensation, do not connect the controller to the mains voltage before
ƒ
the moisture has evaporated completely.
The controller must be protected by external fuses.
ƒ
Unused control inputs and outputs must be closed according to the intended type of
ƒ
protection.
