Be sure not to operate electrical equipment with wet hands.
Otherwise, there is a danger of electric shock and/or injury.
Do not damage cables caused by stress or sandwich.
Otherwise, there is a danger of electric shock.
Operating:
Please do not open the inverter’s case or optional case when the power supply is on and please
do not carry out the following operations when the power supply is on.
(1) Please do not touch the inside (ex. terminal parts).
(2) Please do not check the internal signal.
(3) Please do not put on or take off the internal wiring and connector.
Otherwise, there is a danger of electric shock and/or fire.
Do not touch the conductive parts such as the internal PCB, terminals or connector while power
is being supplied.
Otherwise, there is a danger of electric shock.
Be sure not to remove this product while inverter is powered ON.
Otherwise, there is a danger of electric shock and/or fire.
Maintenance, Inspection and Part Replacement:
Wait at least 10 minutes after turning off the input power supply before performing maintenance
and inspection.
(Confirm that charge lamp on the inverter is off, check the direct current voltage between P-N
terminals and confirm it is less than 45V)
Otherwise, there is a danger of electric shock.
