ENGLISH
Wiring
• Do not operate the switches/buttons with wet hands.
Doing so could cause electric shock.
• Before opening the cover of the inverter to mount the multi-functional keypad, turn OFF the inverter and
wait for at least five minutes for models of 22 kW or below, or ten minutes for models of 30 kW or above.
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, sheaths of the control signal wires are not specifically designed to withstand a high voltage
(i.e., reinforced insulation is not applied). Therefore, if a control signal wire comes into direct contact
with a live conductor of the main circuit, the insulation of the sheath might break down, which would
expose the signal wire to a high voltage of the main circuit. Make sure that the control signal wires will
not come into contact with live conductors of the main circuit.
Otherwise, an accident or electric shock could occur.
Disposal
• For disposal, treat the multi-function keypad as industrial waste.
Otherwise injuries could occur.
Others
• Never attempt to modify the multi-function keypad or inverter.
Doing so could cause electric shock or injuries.
GENERAL PRECAUTIONS
Drawings in this manual may be illustrated without covers or safety shields for explanation of detail parts.
Restore the covers and shields in the original state and observe the instructions given in the manual before
starting operation.
