Cautions and Warnings
WARNING
Do not touch the Inverter terminals while the power is being supplied.
WARNING
Maintenance or inspection must be performed only after turning OFF the power
supply, confirming that the CHARGE indicator (or status indicators) is turned OFF,
and after waiting for the time specified on the front cover. Not doing so may result in
electrical shock.
WARNING
Maintenance, inspection, or parts replacement must be performed by authorized
personnel. Not doing so may result in electrical shock or injury.
WARNING
Do not attempt to take the Unit apart or repair. Doing either of these may result in
electrical shock or injury.
Caution
Carefully handle the Inverter because it uses semiconductor elements. Careless
handling may result in malfunction.
Caution
Do not change wiring, disconnect connectors, the Operator, or optional items, or
replace fans while power is being supplied. Doing so may result in injury, damage to
the product, or malfunction.
