11081.C SOFT STARTERS Enclosures MVX soft starters can be installed easily into standard enclosures to provide a complete motor control cabinet. The compact size of the power assembly leaves room for auxiliary equipment to be installed. The phase cassette should be mounted at the bottom of the enclosure, and the Controller can be mounted on the front panel. The diagrams below illustrate a possible configuration for installation. 2 5 1 3 6 7 4 8 9 Front view Side view Rear view 1 Controller compartment 6 Bypass contactor/ circuit breaker 2 Upper LV compartment 7 Surge arrester 3 Main contactor/ circuit breaker compartment 8 Phase cassette power connections 4 Phase cassette 9 Earth switch 5 Input supply terminals 710-12280-00A Medium Voltage Application Guide Page 39
