Operation
• Be sure to install the terminal block cover and the front cover before turning the power on. Do not re-
move the covers while power is applied.
Otherwise electric shock could occur.
• Do not operate switches/buttons with wet hands.
Doing so could cause electric shock.
• If the retry function has been selected, the inverter may automatically restart and drive the motor de-
pending on the cause of tripping. Design the machinery or equipment so that human safety is ensured
after restarting.
• Never make an alarm reset with the operation signal being on. Doing so will suddenly restart the in-
verter. Ensure that the operation signal is turned off beforehand.
Otherwise an accident could occur.
• If you set the function codes wrongly or without completely understanding this instruction manual, the
FRENIC-Lift Instruction Manual (INR-SI47-1038-E) and the FRENIC-Lift Reference Manual
(INR-SI47-1068-E), the motor may rotate with a torque or at a speed not permitted for the machine.
An accident or injuries could occur.
• Do not touch the inverter terminals while the power is applied to the inverter even if the inverter stops.
Doing so could cause electric shock.
Wiring
• Do not operate the switch with wet hands.
Doing so could cause electric shock.
• Before opening the cover of the inverter to install the multi-function keypad, turn the power off and wait
for at least five minutes. Further, make sure that the LED monitor is turned off, the charger indicator is
off, and the DC link bus voltage between the terminals P (+) and N (-) has dropped below the safe
voltage level (+25 VDC), using a circuit tester or another appropriate instrument.
Otherwise electric shock could occur.
• In general, the insulation property of the sleeve of the signal wire and that of the sheath of the signal
cable are not sufficient for high voltages. Therefore, if a signal wire or cable comes into direct contact
with a live part of the main circuit, the insulation may be broken, causing the signal wire to be exposed to
the high voltage of the main circuit. Be sure to keep all signal wires and cables away from live parts of
the main circuit.
Otherwise, an accident or electric shock could occur.
