Grounding
Be sure to ground the unit and differential protection
should be suited for industrial machinery with current
leak which can be higher than 300 mA (several motors
and frequency drives).
CAUTION!
To avoid corrosion, overheating or general damage,
at terminal connections of power supply wiring, unit
is designed for copper mono-conductors only. In case
of multiconductor cable, an intermediate connection
box must be added. For cable with alternative material,
bi-material connecting devices are mandatory. Cable
routing inside control panel should be made case by
case by installer.
