CAUTION
• Never install an MxC that is damaged or has missing components.
Failure to do so may result in injury.
CAUTION
• Always hold the case when carrying the MxC.
If the MxC is held by the front cover, the main body of the MxC may fall, possibly resulting in injury.
• Attach the MxC to a noncombustible material, such as a metallic surface.
Attaching the MxC to combustible material may cause a fire.
• Install a cooling fan or other cooling device when installing more than one MxC in the same enclo-
sure so that the temperature of the air entering the MxCs is below 45 °C.
Fire or other damage may result if the MxC overheats.
WARNING
• Always turn off the input power supply before wiring terminals.
Failure to do so may result in electric shock or fire.
• Wiring must be performed by an authorized person qualified in electrical work.
Electric shock or fire may result if an untrained individual attempts to wire the MxC.
• Be sure that the ground terminal is properly grounded.
200 V class: Ground to 100 Ω or less 400 V class: Ground to 10 Ω or less
Failure to do so may result in electric shock or fire.
• Always check emergency stop circuits after they are wired.
Failure to verify that all emergency stops are working properly may result in serious injury. The user is responsible for
properly wiring the product.
• Never touch the output terminals directly with your hands or allow the output lines to come into con-
tact with the MxC case. Never short the output circuits.
Failure to do so may result in a ground short or electric shock.
• Before turning the power on, make sure that the power LED is off. If the unit is switched on while
the power LED is lit, the motor will start automatically.
Failure to check the power LED may result in injury.
• If the MxC is set up for a 3-wire sequence, then be sure that the multi-function input terminals have
been set properly before wiring the control circuit.
Failure to do so will cause the motor to rotate unexpectedly, and may result in damage or personal injury.
