Maintenance And Inspection - Orientalmotor FE100 Operating Manual

2 Safety precautions
Connection and wiring
• Connect the inverter properly in accordance with the connection diagram. Failure
to do so may result in fire or electric shock.
• Use cables of the specified sizes. Failure to do so may result in fire.
• Do not forcibly bend, pull or pinch the power supply cable and lead wires or other
inverter cables. Doing so may result in electric shock or fire.
• After connecting the inverter, be sure to install terminal covers (supplied with the
inverter) on the main circuit terminals of the inverter. Failure to do so may result
in electric shock.
• After wiring an emergency-stop circuit, always conduct operation check. Failure
to do so may result in injury.
• Connect the inverter to the power supply via a protective device (such as a
molded-case circuit breaker). Failure to do so may result in fire, injury or damage
to the equipment.
Operation
• Do not operate the inverter with its live parts exposed. Doing so may result in
electric shock.
• Turn off the inverter power in the event of power outage. If not, the motor may
suddenly start once the power is restored, thus causing injury or damage to the
equipment.
• Do not operate the switches with wet hands. Doing so may result in electric shock.
• Do not touch the inverter terminals even when the inverter is not operating.
Install/remove the covers or set the DIP switches after confirming that the inverter
power has been turned off. Failure to observe these instructions may result in
electric shock.
• Provide a separate emergency-stop switch. Absence of an emergency-stop switch
may result in injury.

Maintenance and inspection

• Some of the inverter terminals carry high voltage. To protect against the danger of
electric shock, do not touch the terminals with bare hands within 1 minute after
turning off the inverter power.
• Before commencing any maintenance or inspection work, turn off the inverter
power, confirm that all indicator lamps have turned off, and then wait at least
20 minutes thereafter. The inverter surface and radiating fins are still very hot
immediately after the power is turned off, so touching the inverter in this
condition may result in skin burn(s).
• Do not perform withstand voltage test on the inverter or megger test on its control
circuit. Doing so may result in injury or damage to the equipment.
• Keep the inverter's radiating fins from collecting dust or other foreign deposits.
Foreign deposits on the radiating fins may cause fire.
• No one other than qualified personnel should be allowed to perform maintenance
or inspection of the inverter or replace any of its parts. When performing
maintenance or inspection or replacing parts, always use insulated tools. Failure to
observe these instructions may result in electric shock or injury.
