10.8.2 Contactor Switches
The mains contactor is an option. All units ordered and supplied with a factory-installed contactor require a Class L/J branch circuit
fusing to meet the 65 kA SCCR for the drive system.
This option makes it possible to connect or disconnect the drive from the mains by using a control switch on the control compart-
ment door or an external switch. The external switch must be wired to terminals XD0. See 5.3 Wiring Overview for D9h and D10h
Enclosed Drives and 5.4 Wiring Overview for E5h and E6h Enclosed Drives. The mains contactor is supplied with 2 sets of auxiliary
switches (1 normally open and 1 normally closed). These switches are on the sides of the contactor. By default, the NO auxiliary
switch is wired at the factory and used by the system.
