Electrical Installation
All variable-speed motors should be connected using shielded cables,
Rule 9
whereby the shield is connected at both ends to the housings through the
largest possible surface area to minimize the inductance. The motor
feeder cables should also be shielded outside the cabinet, or at least
screened using barriers.
Cables with steel shield are not suitable.
To connect the shield at the motor, a suitable PG gland with shield
connection can be used (e.g. "SKINDICHT SHV/SRE/E" from the Lapp
Company, Stuttgart). It should be ensured that the connection between
the motor terminal box and the motor housing has a low impedance.
Otherwise, use an additional grounding strap between them. Never use
plastic motor terminal boxes!
The shield between the motor and drive controller may not be interrupted
Rule 10
by installing components such as output reactors, sinusoidal filters, motor
filters, fuses, contactors. The components must be mounted on mounting
panels which also simultaneously serve as shield connection for the
incoming and outgoing motor cables. If required, metal barriers may be
required to shield the components.
