MAINTENANCE AND INSPECTION
• Never touch high-voltage terminals on the
Inverter.
Failure to observe this warning may result in an elec-
trical shock.
• Disconnect all power before performing mainte-
nance or inspection, and then wait at least one
minute after the power supply is disconnected.
Confirm that all indicators are OFF before pro-
ceeding.
If the indicators are not OFF, the capacitors are still
charged and can be dangerous.
• Do not perform withstand voltage test on any
part of the Varispeed V7.
The Inverter is an electronic device that uses semi-
conductors, and is thus vulnerable to high voltage.
• Only authorized personnel should be permitted
to perform maintenance, inspection, or parts
replacement.
(Remove all metal objects (watches, bracelets, etc.)
before starting work.)
(Use tools which are insulated against electrical
shock.)
Failure to observe these warnings may result in an
electric shock.
