Warning
Prohibited
• Observe all permissible operating ranges of motors and mechanical equipment. (Refer to the motor's
instruction manual.)
Not observing these ranges may result in injury.
When sequence for restart after a momentary failure is selected (inverter)
Warning
Mandatory
• Stand clear of motors and mechanical equipment.
If the motor stops due to a momentary power failure, the equipment will start suddenly after power
recovers. This could result in unexpected injury.
• Attach warnings about sudden restart after a momentary power failure on inverters, motors and
equipment for prevention of accidents in advance.
When retry function is selected (inverter)
Warning
Mandatory
• Stand clear of motors and equipment.
If the motor and equipment stop when the alarm is given, selection of the retry function will restart them
suddenly after the specified time has elapsed. This could result in unexpected injury.
• Attach warnings about sudden restart in retry function on inverters, motors and equipment for
prevention of accidents in advance.
Maintenance and inspection
Danger
Prohibited
• Do not replace parts.
This could be a cause of electric shock, fire and bodily injury. To replace parts, call the local sales
agency.
Mandatory
• The equipment must be inspected every day.
If the equipment is not inspected and maintained, errors and malfunctions may not be discovered and
that could result in accidents.
• Before inspection, perform the following steps.
(1) Turn off all input power to the inverter.
(2) Wait at least ten minutes and check to make sure that the charge lamp is no longer lit.
(3) Use a tester that can measure DC voltages (800VDC or more), and check to make sure that the
voltage to the DC main circuits (across PA-PC) is 45V or less.
If inspection is performed without performing these steps first, it could lead to electric shock.
