8.0 MAINTENANCE AND INSPECTION Warning Be sure to disconnect AC power and ensure that the internal capacitors have fully discharged before performing the maintenance and inspection.

Warning Do not touch any internal or exposed parts of servo drive and servo motor as electrical shock may result. Do not remove the operation panel while the drive is connected to an electrical power source otherwise electrical shock may result. Wait at least 10 minutes after power has been removed before touching any drive or motor terminals or performing any wiring and/or inspection as an electrical charge may still remain in the servo drive and servo motor with hazardous voltages even after power has been removed. Do not disassemble the servo drive or motor as electric shock may result. Do not connect or disconnect wires or connectors while power is applied to the drive and motor. Only qualified personnel who have electrical 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/or damaged. Do not disassemble or damage any mechanical part when performing maintenance. Clean off any dust and dirt with a vacuum cleaner. Place special emphasis on cleaning the ventilation ports and PCBs. Always keep these areas clean, as accumulation of dust and dirt can cause unforeseen failures.
