EMI - Electronic Interference

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).

NOTE!

It is recommended to use shielded cables for the Dix inputs when

using long cables (above 30 m) in noisy environments. The metallic

shield and A2 must be grounded.
