Rockwell Automation 36С47 DC Drive Output Contactor Kit 300-500HP - Manual (Page 2)

1. Disconnect all power to the AĆC VLS Drive before
installing this kit.
DANGER
EQUIPMENT IS AT LINE VOLTAGE WHEN
THE INPUT DISCONNECT IS ON. THE INPUT
DISCONNECT MUST BE OFF BEFORE IT IS
SAFE TO TOUCH ANY INTERNAL PARTS OF
THIS EQUIPMENT. AFTER POWER IS
REMOVED, THE COMMUTATION CAPACIĆ
TORS CAN REMAIN CHARGED. ALLOW
TWO MINUTES BEFORE TOUCHING ANY
INTERNAL PARTS OF THE CONTROLLER.
FAILURE TO OBSERVE THESE PRECAUĆ
TIONS COULD RESULT IN FATAL INJURY.
NOTE: If the Output Contactor Kit and the Control Circuit
Transformer Kit are to be installed, mount the Output
Contactor Kit first because the Control Circuit Transformer
Kit normally occupies the same location as the Output
Contactor Kit. The Control Circuit Transformer Kit must be
relocated as defined in Instruction Sheet D2Ć3014.
2. Disconnect motor leads T1, T2 and T3 from the output
bus bar assembly (Figure 1). Disconnect bus bars
601, 602 and 603 from the output bus bar assembly
(Figure 1). Remove the output bus bar assembly by
removing the four taptite screws. This assembly will
not be used while the Output Contactor Kit is installed.
3. Snap the Auxiliary Contact (76624ĆX) into the cavity on
the front left of the Contactor (Figure 2). Secure with
the captive lock screw provided.
4. Using the four furnished 5/16Ć18 x 1/2" hex washer
head screws, mount the Contactor (705310Ć9R) in the
