Operation and Safety
The PDU is intended for indoor use only. Do not use the device outdoors. If the product has an exposed circuit board, never touch it while the unit is powered. The circuit breaker acts as a master switch for all power; if a surge occurs, the breaker will trip. To reset, push the breaker button. The Protection Present LED should remain solid green during normal operation; if it is off, the surge protection may be damaged.
Maintenance and Disposal
Ensure all screws are properly tightened during periodic inspections. The product is backed by a two-year warranty. For disposal, follow local regulations regarding electronic waste, as the unit contains components that should be recycled appropriately.
