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.
Sequence of Operation
1. Read and follow safety precautions.
2. After installation, ensure that:
a. All filter ground terminals are connected to ground.
b. Power wiring to the utility, drive 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 the filter output from the drive.
5. Connect the filter to the utility.
6. Confirm that line voltage is present at the input terminals (U1, V1, W1) of the filter.
7. Confirm that line voltage is present at the output terminals (U2, V2, W2) of the filter and that it is
less than or equal to 1.05 times the input voltage.
8. Using a clamp on Amp meter, check input phase currents to verify they are within a 5% match to
each other and approximately 30% of filter current rating.
9. Remove power and verify that
NO VOLTAGE
is present on the filter terminals.
10. Connect the filter output to the drive.
11. Refer to the drive user manual for the drive start-up procedure. Observe all safety instructions in
the drive user manual.
