Stop!
The device contains components that can be destroyed by electrostatic
discharge!
Before working on the device, the 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).
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.
The following connections need not be shielded:
24 V supply
ƒ
Digital signals (inputs and outputs)

Death or severe injuries when touching the power terminals.
Before working on the power connections, wait at least until the discharge
time has passed (depending on the device, this may be up to 30 minutes).
Make sure that all power terminals are deenergised.
