Warnings and Cautions for Troubleshooting and Maintenance
General Warnings and Cautions
WARNING: Never modify the unit. Otherwise, there is a danger of electric shock and/
or injury.
CAUTION: Withstand voltage tests and insulation resistance tests (HIPOT) are
executed before the units are shipped, so there is no need to conduct these tests before
operation.
CAUTION: Do not attach or remove wiring or connectors when power is applied. Also,
do not check signals during operation.
CAUTION: Be sure to connect the grounding terminal to earth ground.
CAUTION: When inspecting the unit, be sure to wait five minutes after tuning OFF the
power supply before opening the cover.
WARNING: Wait at least five (5) minutes after turning OFF the input
power supply before performing maintenance or an inspection. Other-
wise, there is the danger of electric shock.
...... 6–2
WARNING: Make sure that only qualified personnel will perform
maintenance, inspection, and part replacement. Before starting to work,
remove any metallic objects from your person (wristwatch, bracelet,
etc.). Be sure to use tools with insulated handles. Otherwise, there is a
danger of electric shock and/or injury to personnel.
...... 6–2
WARNING: Never remove connectors by pulling on its wire leads (wires
for cooling fan and logic P.C.board). Otherwise, there is a danger of fire
due to wire breakage and/or injury to personnel.
...... 6–2
CAUTION: Do not connect the megger to any control circuit terminals
such as intelligent I/O, analog terminals, etc. Doing so could cause
damage to the inverter.
.... 6–10
CAUTION: Never test the withstand voltage (HIPOT) on the inverter.
The inverter has a surge protector between the main circuit terminals
above and the chassis ground.
.... 6–10
HIGH VOLTAGE: Be careful not to touch wiring or connector terminals
when working with the inverters and taking measurements. Be sure to
place the measurement circuitry components above in an insulated
housing before using them.
