1. Items related to prevention of electric shocks
WARNING
Do not open or remove 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 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, drive unit and motor 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, drive unit and motor 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.
