WARNING
Electrical Shock Prevention
1. Do not remove the front cover when input power
is applied. Doing so can result in electric shock.
2. Do not operate the inverter with the front cover
removed. Electric shock can occur due to the
exposed high voltage terminals and capacitor.
3. Do not remove the cover except for routine
inspections or wiring, even if the input power is
not applied. The capacitor will remain charged
for a long time even when the power is not
applied.
4. Wiring and routine checkups should be
performed 10 minutes after disconnecting the
input power and after checking to see whether
the DC voltage is discharged with a tester.
(Below DC 30V)
5. Do not use a higher grounding method than the
Type 3 grounding method.
6. Only authorized personnel may perform wiring
and inspections.
7. Wire the inverter after the inverter installation.
8. Do not operate the switches with wet hands.
Doing so may result in electrical shock.
9. Electrical shock may occur if the cable insulation
is damaged. Insure proper mounting of
equipment to minimize excess stress on power
cables.
CAUTION
Fire Prevention
1. Install the inverter on a non-combustible surface.
Installing the inverter on or near combustible
materials can result in fire.
2. Disconnect the inverter when the inverter is
damaged. Failure to do so could lead to a
secondary accident and fire.
3. Do not connect a resistance directly between the
DC terminals P. N. Doing so can result in fire.
Damage Prevention
1. Do not apply voltages higher than the values
specified in this manual to the terminals. Doing
so can damage the inverter.
2. Incorrect terminal connection may damage the
inverter.
3. Incorrectly connecting the polarity (+/-) of the
terminals can damage the inverter.
4. After disconnecting, the inverter may still be hot.
Use caution to prevent the possibility of personal
injury.
