Notes for cable routing outside the control cabinet:
ƒ The longer the cables the greater the space between the cables must be.
ƒ If cables for different signal types are routed in parallel, the interferences can be
minimized by means of a metal barrier or separated cable ducts.

Wiring on the motor side
) Note!
The motor cable is highly susceptible to interference. Therefore you will
achieve an optimum wiring on the motor side if you
ƒ exclusively use shielded and low−capacitance motor cables.
ƒ do not integrate any further cable into the motor cable (e.g. for blowers
etc.).
ƒ shield the supply cable for temperature monitoring of the motor (PTC or
thermostat) and install it separately from the motor cable.
