6.4 Mains and motor connection
Check that the mains voltage and frequency correspond
to the values on the nameplate of CUE and the motor.
The motor cable must be screened for CUE to meet EMC
requirements.
The supply voltage and frequency are marked on the CUE
nameplate. Make sure that CUE is suitable for the power supply
of the installation site.
6.4.1 Main switch
A main switch can be installed before the CUE cabinet according
to local regulations. See figure Example of three-phase mains
connection of CUE with main switch, backup fuses and additional
protection.
6.4.2 Wiring diagram
The wires in the terminal box must be as short as possible.
Excepted from this is the protective conductor which must be so
long that it is the last one to be disconnected in case the cable is
inadvertently pulled out of the cable entry.
