Lift Truck
A lift truck is required for all primary devices. The lift truck docks with the MCC, allowing a primary device to be
raised or lowered to the appropriate height and safely rolled into the controller compartment. The lift truck has
wheels for easy maneuvering in restricted aisle space common to MV MCC installations. A motor lift is available
as an option. All primary devices have self-contained wheels for easy floor rolling.
•
Always follow safe work practices when lifting the controllers to protect the safety
of personnel and equipment.
•
Always inspect lift truck for signs of wear or damage before use.
•
Do not use a lift truck that is damaged or worn.
•
The lift truck IS NOT to be used for insertion of drawout controllers into MCC
compartments.
•
The lift truck IS NOT to be used as the sole means of support when servicing the
controller.
Racking Handle
The racking handle is designed to easily adjust the device into and out of a MCC compartment. It is also used
to change the position of the device from the Disconnect and Connect positions. Press down on the release
lever and rotate racking handle clockwise to rack in (toward Connect) and counter clockwise to rack out (from
Connect).

•
Use of any other racking device not approved by ABB will void the warranty!!
•
ABB will not be responsible for damage caused by the use of racking tools other than ABB's.
Test Jumper
A "test jumper" is an extension cord. It allows connection of secondary contacts on a vacuum controller to
the MCC while outside a controller compartment. This enables the controller to be electrically operated using
controls in the MCC, or electrically charged after manual operation of the controller in a MCC aisle.
Test Cabinet
A "test cabinet" is a wall-mounted control cabinet connected to a separate power source and containing
switches to open and close a controller. The test cabinet has a female connector and an umbilical cord (stored
inside the cabinet) for connection to the controller, and serves as an aid to controller inspection and maintenance
in MCC aisles or work áreas.
