Preliminary Checklist Contactor Operation
To avoid shock hazards, lock out incoming power before
working on the equipment. Verify with a hot stick or
appropriate voltage measuring device that all circuits are
voltage free. Failure to do so may result in severe burns,
injury or death.
1) Connect the appropriate external power supply (120 or 230 VAC) to
the test receptacle in the control panel. Turn the selector switch to the
TEST position (see Figure 3.2).
2) Electrically operate the contactor several times. Inspect the armature
plate to verify that it fully contacts the cores (400A) or yolk plate (800A).
3) Turn the selector switch back to the OFF position and disconnect the
test power supply.
Electrical Connections
1) Verify correct power cable phase sequencing and that the connections
are tight. See Torque Requirements, page 1-4.
2) Verify power fuse ratings and condition.
3) Verify control fuse ratings and condition.
4) Check that components were not damaged during power cable
installation, and that electrical spacings are suffi cient.
Final Checks
1) Remove all tools from the cabinet. All tools and hardware used
during installation and commissioning must be accounted for prior to
energizing the unit.
2) Remove all temporary jumpers and grounding devices used during the
installation procedures.
3) Ensure that all barriers or covers removed during installation have been
securely reattached.
4) Close and secure all doors. Verify that all interlocks preventing access
to medium voltage power cells are functioning correctly.
Use suitable personal protective equipment (PPE) per
local codes or regulations. Failure to do so may result in
severe burns, injury or death.
5) Restore incoming power from main power supply.
6) Move the isolation switch handle to the ON position.
7) The controller is now ready to supply power to the load.
