Warning

Be sure to disconnect AC power and ensure that the internalcapacitors have fully discharged before performing the maintenance

and inspection.

Warning

Do not touch any internal or exposed parts of servo drive and servomotor as electrical shock may result. Do not remove the operationpanel while the drive is connected to an electrical power sourceotherwise electrical shock may result. Wait at least 10 minutes afterpower has been removed before touching any drive or motor

terminals or performing any wiring and/or inspection as an electricalcharge may still remain in the servo drive and servo motor withhazardous voltages even after power has been removed. Do notdisassemble the servo drive or motor as electric shock may result.Do not connect or disconnect wires or connectors while power isapplied to the drive and motor. Only qualified personnel who haveelectrical knowledge should conduct maintenance and inspection.

MAINTENANCE & INSPECTION

Use and store the product in a proper and normal environment.Periodically clean the surface and panel of servo drive and motor.Make sure the conductors or insulators are corroded and/ordamaged. Do not disassemble or damage any mechanical part whenperforming maintenance.Clean off any dust and dirt with a vacuum cleaner. Place specialemphasis on cleaning the ventilation ports and PCBs. Always keepthese areas clean, as accumulation of dust and dirt can causeunforeseen failures.
