1. Items related to prevention of electric shocks
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.
Completely turn off the all lines of the power supply externally before wiring. Not completely turning off all
power could result in electric shock or damage to the product.
When turning on the power supply or operating the module after wiring, be sure that the module's terminal
covers are correctly attached.
Not attaching the terminal cover could result in electric shock.
