Motor terminal box
Fig. 3-11 Shield connection at the motor
The shield can be connected through a PG gland (nickel-plated brass)
with a strain relief bar. Thus, the degree of protection IP 20 can be
achieved.
For higher degrees of protection (up to IP 68), there are special PG
glands with shield connection, e.g.:
♦ SKINDICHT SHVE, Messrs. Lapp, Stuttgart
♦ UNI IRIS Dicht or UNI EMV Dicht, Messrs. Pflitsch, Hückeswagen
It is not permissible to use plastic motor terminal boxes!
