STARTUP
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 utility. This voltage is extremely
dangerous and may cause death or
severe injury if you come in contact with
it.
WARNING
After disconnecting the utility power,
wait at least 5 minutes before doing any
work on the filter connections. After
removing power, allow at least five
minutes to elapse and verify that the
capacitors have discharged to a safe
level before contacting internal
components. Connect a DC voltmeter
across the capacitor terminals. Start
with the meter on the highest scale and
progressively switch to a lower scale as
the indicated voltage falls below the
maximum value of the scale used.
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. Use the guidelines of table
10 for power and cap-panel wire
gauges.
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.
WARNING
Use extreme caution to avoid contact
with line voltage when checking for
power.
INJURY OR DEATH MAY RESULT
IF SAFETY PRECAUTIONS ARE NOT
OBSERVED.
6. Confirm that line voltage is present at
the input terminals (U, V1, W1) of the
filter.
7. Confirm that line voltage is present at
the output terminals (U2, V2, W2) of the
filter.
8. Disconnect the filter from the utility.
9. Connect the filter output to the drive.
10. Refer to the drive user manual for the
drive startup procedure. Observe all
safety instructions in the drive user
manual.
WARNING
INJURY OR DEATH MAY RESULT IF THE
DRIVE SAFETY PRECAUTIONS ARE NOT
OBSERVED.
WARNING
Damage to equipment may occur if the drive
startup procedures are not observed.
