Wiring the basic device
Danger!
All power terminals carry hazardous voltages up to 3 minutes after mains
disconnection.
Stop!
The device contains components that can be destroyed by electrostatic
discharge!
Before working on the device, the personnel must remove any electrostatic
charges using suitable measures.
Design of the cables
The cables used must comply with the approvals required for the location (e.g. UL).
ƒ
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
ƒ
These connections do not require shielding:
24 V supply
ƒ
Digital signals (inputs and outputs)
