For Safe Use
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.
CAUTION
Install the controller, drive unit, motor and regenerative resistor on non-combustible material. Installation directly on
or near combustible materials could result in fires.
If any malfunction in the unit is observed, shut off the power at the unit’s power supply side. Continuous flow of
large current could result in fires.
Install an appropriate no fuse breaker (NFB) and contactor (MC) on the power input section of the drive unit and
configure the sequence that shuts the power off upon drive unit’s emergency stop or alarm.
When a breaker is shared for multiple power supply units, the breaker may not function upon short-circuit failure in
a small capacity unit. Do not share a breaker for multiple units as this is dangerous.
Incorrect wiring and connections could cause the devices to damage or burn.
