The Soft-Starter SSW-07 is developed to be used in industrial
systems (Class A) according to Standard EN60947-4-2.
It’s necessary to have a distance of 0.25 m (10 in) between the
Soft- Starter SSW-07 control cables and motor cables.
Example: PLC wiring, temperature controllers, thermocouple cables,
etc.
Grounding of the Motor frame
Always ground the motor frame. The Soft-Starter SSW-07 output
wiring to the motor must be installed separately from the input wiring
as well as from the control and signal wiring.
The control connections (digital inputs and relay outputs) are made
through the terminals (refer to figure 3.9).
