5:2.2 Supply voltage and control circuit
When used for marine applications, and if feeding from the
outside of the enclosure, then please use a standard cable
for feeding the supply voltage and for the control circuit, with
an auxiliary bare conductor (earth conductor) and make a
360 degree connection to earth in the glands, or close to the
glands. As long as these cables / wires are only internal
wiring, inside the enclosure, there is no need for the 360
degree earth connections / protections.
5:2.2.1 Supply voltage, terminals 1 and 2
Connect neutral and phase to terminal 1 and 2.
Check that you have the correct supply voltage U
s
.
5:2.2.2 Earthing, terminal 3
Connect the cable to a earthing point close to the softstarter.
The cable should be as short as possible. A suitable earthing
point would be next to the softstarter on the mounting plate,
see Figure 8. The mounting plate should also be earthed.
This is not a protective earth, it is a function earth. The
earthing cable should be as short as possible. Maximum
length 0.5 m.
