Controller Handling Notes
WARNING
DO NOT touch fins. Their hot surfaces may cause severe burns.
DO NOT insert fingers or foreign objects into openings. Doing so may cause
bodily injury.
Before opening the controller cover and accessing the inside of the controller
for maintenance, be sure to turn off the power switch, disconnect the power
cable, and wait 3 minutes or more. This is for protecting you from electric
shock.
DO NOT connect or disconnect connectors to/from the controller when the AC
power or the 24 VDC power for I/O is being supplied. Doing so may cause
electric shock or controller failure.
CAUTION IN INSTALLATION
This controller is not designed to be dust-proof, splash-proof, or
explosion-proof.
Read operation manuals before installation.
Do not place anything on the controller.
CAUTION
The controller connectors are of a screw-lock type or ring-lock type. Lock the
connectors securely. If even one of the connectors is not locked, weak contact
