Wiring outside of the control cabinet

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.
