3 Start Up and Functional Testing
3.1 Pre-start
3.1.1 Safety Inspection
WARNING
HIGH VOLTAGE!
If input and output connections have been connected
improperly, there is potential for high voltage on these
terminals. If power leads for multiple motors are
improperly run in same conduit, there is potential for
leakage current to charge capacitors within the drive, even
when disconnected from mains input. For initial start up,
make no assumptions about power components. Follow
pre-start procedures. Failure to follow pre-start procedures
could result in personal injury or damage to equipment.
1. Input power to the unit must be OFF and locked
out. Do not rely on the drive disconnect switches
for input power isolation.
2. Verify that there is no voltage on input terminals
L1 (91), L2 (92), and L3 (93), phase-to-phase and
phase-to-ground,
3. Verify that there is no voltage on output
terminals 96 (U), 97 (V), and 98 (W), phase-to-
phase and phase-to-ground.
4. Confirm continuity of the motor by measuring
ohm values on U-V (96-97), V-W (97-98), and W-U
(98-96).
5. Check for proper grounding of the drive as well
as the motor.
6. Inspect the drive for loose connections on
terminals.
7. Record the following motor-nameplate data:
power, voltage, frequency, full load current, and
nominal speed. These values are needed to
program motor nameplate data later.
8. Confirm that the supply voltage matches voltage
of drive and motor.
