CAUTION: Risk of electric shock.
When the power is on, DO NOT touch the AC terminals, an electric shock may
occur. Make sure the power is disconnected when you check the input power supply.
1. Prevent dust or metallic debris from falling into the controller and causing malfunctions. DO
NOT modify the controller.
2. The PXU is an open-type device. Make sure it is installed in an enclosure free of dust and
humidity in case of an electric shock.
3. Wait for one minute after the power is switched off to allow the unit to discharge. DO NOT touch
the internal wiring within this period of time.
