6. START-UP
Safety Precautions
Before start-up, observe the following warnings and instructions:
WARNING
Internal components of the filter are at line potential when the filter is
connected to the drive. This voltage is extremely dangerous and may cause
death or severe injury if you come in contact with it.
Use extreme caution to avoid contact with line voltage when checking for
power.
INJURY OR DEATH MAY RESULT IF SAFETY PRECAUTIONS
ARE NOT OBSERVED.
Damage to equipment or serious injury may occur if the inverter start-up
procedures are not observed.
Caution
Damage to the filter may occur if the appropriate output carrier frequency
is not observed.
Sequence of Operation
1. Read and follow safety precautions.
2. After installation, ensure that:
•
All filter ground terminals are connected to ground.
•
Power wiring to the utility, drive, filter, and motor is in accordance with the power
wiring connection diagrams shown in installation instructions section.
3. Check that moisture has not condensed on the filter components. If moisture is present,
do not proceed with start-up until the moisture has been removed.
4. Disconnect filter output terminals from the motor.
5. Set the drive switching frequency to the appropriate setting.
•
2kHz – 4kHz (3A – 750A Filters)
6. Connect filter temperature safety overload switch into the control circuit so that the drive
will shut down in an overload situation.
7. Confirm that drive voltage is present at the input terminals (U1, V1, W1) of the filter.
8. Confirm that drive voltage is present at the output terminals (U2, V2, W2) of the filter.
9. Connect the filter output to the motor.
10. Refer to the drive user manual for the drive start-up procedure. Observe all safety
instructions in the drive user manual.
