Close cover properly.
Check that all cable connectors are firmly tightened.
Ensure that input power to the unit is OFF and locked out. Do not rely on
the adjustable frequency drive disconnect switches for input power
isolation.
Verify that there is no voltage on input terminals L1 (91), L2 (92), and L3
(93), phase-to-phase and phase-to-ground.
Verify that there is no voltage on output terminals 96 (U), 97 (V), and 98
(W), phase-tophase and phase-to-ground.
Confirm continuity of the motor by measuring ohm values on U-V (96-
97), V-W (97-98), and W-U (98-96).
Check for proper grounding of the adjustable frequency drive as well as
the motor.
Inspect the adjustable frequency drive for loose connections on
terminals.
Confirm that the supply voltage matches voltage of adjustable frequency
drive and motor.
