Series 4G/8G/16G
Temperature/Process Controllers
DANGER! Caution! Electric Shock! When the power is on, DO NOT touch the AC terminals in case an electric
shock may occur. Make sure the power is disconnected when you check the input power supply.
Prevent dust or metallic debris from falling into the controller and causeing malfunctions. DO NOT modify or
uninstall the controller.
Series 4G/8G/16G is an open-type device. Make sure it is installed in an enclosure free of dust and humidity to
limit the potential for electric shock.
Wait for one minute after the power is switched off to allow the capacitor to discharge. DO NOT touch the internal
wiring within this period of time.
