discharge!
Before working on the device, personnel must ensure that they are free of
electrostatic charge by using appropriate measures.
Design of the cables
The cables used must comply with the approvals required for the location (e.g. UL).

The effectiveness of a shielded cable is reached by:
ƒ
– Providing a good shield connection through large-surface shield contact.
– Using only braided shields with low shield resistance made of tin-plated or
nickel-plated copper braid.
– Using braided shields with an overlap rate > 70 % and an overlap angle of 90 °.
– Keeping unshielded cable ends as short as possible.
Use system cables or shielded cables for these connections:
Analog signals (inputs and outputs)
ƒ
System bus CAN
ƒ
Resolver
ƒ
Encoder
