1. Items related to prevention of electric shocks.
Do not open/close the front cover while the power is ON or during operation. The high voltage
terminals and charged sections will be exposed, and this could result in electric shocks.
Do not remove the front cover even when the power is OFF, except for the wiring works or periodic
inspections. The inside of the controller and servo drive unit are charged, and this could result in
electric shocks.
Always wait at least 15 minutes after turning the power OFF. Then, check the voltage with a tester,
etc., before wiring works, inspections or connecting with peripheral devices. Failure to observe this
could result in electric shocks.
Earth ground the controller, servo drive unit and servomotor according to the local laws. (In Japan,
ground the 200V Series input products with Class C or higher protective grounding and the 400V
Series input with Class D or higher protective grounding.)
All wiring works, maintenance and inspections must be carried out by a qualified technician. Failure
to observe this could result in electric shocks. Contact your nearby Service Center or Service
Station for replacing parts and servicing.
Wire the controller, servo drive unit and servomotor after installation. Failure to observe this could
result in electric shocks.
Do not operate the switches with wet hands. Failure to observe this could result in electric shocks.
Do not damage, apply excessive stress, place heavy things on or sandwich the cables. Failure to
observe this could result in electric shocks.
Insulate the power lead using a fixed terminal block. Failure to observe this could result in electric
shocks.
