IMPORTANT SAFETY INSTRUCTIONSSAVE THESE INSTRUCTIONS
This manual contains important instructions for the HTUPS that should be followed during
installation and maintenance of the HTUPS.
Please read and observe the following safety points at all times.
CAUTION: When the On/Off switch is on, the Battery Power supplied outlets are energized, even when
the unit is not plugged in.
CAUTION: To reduce the risk of electric shock, use only indoors and in dry locations. Do not allow the device
to be exposed to moisture, rain, dust, excessive heat or direct sunlight.
CAUTION: Connect this device to a 3-prong-grounded outlet. Make sure the circuit branch is protected and not
servicing equipment requiring heavy electricity.
CAUTION: Never plug the device into itself; this will short-circuit the unit.
CAUTION: This device may be damaged if connected to a motor-powered AC generator with voltage and frequency
output beyond nominal accepted ranges.
CAUTION: Risk of Electrical Shock! The battery circuit is not isolated from AC input. Hazardous voltage may exist
between the terminal and ground. Disconnect the power cord from the wall receptacle before servicing the battery.
CAUTION: The output of this device is not sinusoidal. It has a total harmonic distortion of 49% and maximum single
harmonic distortion of 32%, to be used with home theater equipment and computer loads only.
