● Lay the connecting cables and in particular the PE conductor in the terminal box in an open
arrangement so that chafing of the cable insulation is prevented.
● Connect the machine in such a way that a permanent, safe electrical connection is
maintained. Avoid protruding wire ends.
● Lay and secure external auxiliary cables separately from the main cable. Elements with
cable ties may be present for this purpose.
● In case of high humidity or when installed outside, water drops can move along the cable
jacket and enter the motor through the cable entry and cable gland.
If you route the cable with an appropriate loop then water doesn't enter the terminal box, but
simply drips off.
