Wiring the mounting backplane

Stop!
Observe the maximum permissible mains voltage. Any higher voltage will
destroy the device.
Danger!
The leakage current to earth (PE) is > 3.5 mA. According to EN 61800-5-1, a
fixed installation is required. The PE connection must comply with
EN 61800-5-1.
Tip!
Complete the wiring of the mounting backplane before plugging in the basic
device. The terminals of the mounting backplane cannot be connected with
the basic device plugged in.
Design of the cables
The cables used must comply with the approvals required for the location (e.g. UL).
ƒ
It is imperative to comply with the regulations concerning minimum cross-sections
ƒ
of PE conductors. The cross-section of the PE conductor must be at least as large as
the cross-section of the power connections.
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:
Motor

Motor holding brake
