5:2.2 Control voltage and control circuit
5:2.2.1 Control voltage, terminals 1 and 2
Connect the hot and neutral and phase to terminals 1 and 2.
Check that you have the correct control voltage U
s
.
5:2.2.2 Grounding, terminal 3
Connect the cable to a grounding point close to the softstarter.
The cable should be as short as possible. A suitable grounding point
would be next to the softstarter on the mounting plate, see Figure 7.
The mounting plate should also be grounded.
This is not a protective ground, it is a functional ground. The
grounding cable should be as short as possible.
