4. START UP
Startup Checklist
Safety Precautions
Before startup, 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 may occur if the drive startup procedures are 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 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 startup 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 startup procedure. Observe all safety
instructions in the drive user manual.
