Control Wiring - Power Electronics V2 Series User Manual

Magnetic protection is required to protect the V2 soft-starter from damage due to a short circuit within
the V2 or on the output cabling or motor. When a faster protection was needed, it is recommended ultra
fast fuses. The fuses should be mounted as close to the V2 soft-starter as possible. Power factor
correction capacitors must not be connected after the fuses or on the output of the V2.
The V2 protects the motor with electronic overload sensing, so an external overload relay is not
necessary. If multiple motors are connected separate, overloads are required for each motor.
An isolator can be fitted after the V2 but is recommended for off load use only. A motor isolator is not
necessary for the operation of the V2 soft-starter but site standards or electrical wiring regulations may
require an isolator near the motor.
If a contactor is to be fitted, an output relay of the soft starter can energize it on receiving the start
signal.

1. 6 CONTROL WIRING

NOTE: Wiring distance.
Control wiring shouldn't run in parallel with power input or output cables to the motor. Space
at least 300mm away, and cross at right angles.
Control terminals:
The control terminals do need to be screened when running in parallel with power cables.
(Terminals 7 to 13)
Start/Stop wiring:
Wiring options with push buttons or selector (switch) according to Selection 4.2.
