There must be no electrical connection between the encoder system housing and the

encoder system electronics. If this is not carefully observed, under certain circumstances the

system will not be able to reach the required interference immunity level (there is then a

danger of equalization currents flowing through the electronics ground).

When the encoder system is connected via terminals, make sure that the cable shield is

connected to the component.

Connecting cables to temperature sensors must always be installed with shielding. The

cable shield must be connected to the ground potential at both ends over a large surface

area. Temperature-sensor cables that are routed together with the motor cable must be

twisted in pairs and shielded separately.
