Sine Wave 2-8 kHz Series A Filter
37
Part No. INSTR-020 REL. 080310
9. 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 drive 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.
Including those of drive manufactures.
2. After installation, ensure that:
•
All filter ground terminals are
connected to ground.
•
Power wiring to the utility, inverter,
filter and motor is in accordance with
the installation and connection
instructions in Chapter 5.
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.
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.
4. Refer to the inverter user manual
for the inverter startup procedure.
Observe all safety instructions in
the inverter user manual.
5. Disconnect filter output terminals
from the motor.
6. Set the inverter switching
frequency between 2 kHz and 8
kHz. Refer to the inverter user
manual.
CAUTION
Damage to the filter may occur if the
inverter frequency is not set between 2
kHz and 8 Khz.
7. Turn the inverter ON
8. Confirm that inverter voltage is
present at the input terminals (U1,
V1, W1) of the filter.
9. Confirm that inverter voltage is
present at the output terminals (U2,
V2, W2) of the filter.
10. Disconnect the inverter from the
AC Line and wait 5 minutes.
11. Connect the filter output to the
motor.
12. Refer to the inverter user manual
for the motor startup procedure.
