1 IMPORTANT SAFETY INSTRUCTIONS
(SAVE THESE INSTRUCTIONS)
Before attempting to unpack, install, or operate the product, please read and follow all instructions carefully.
CAUTION! To prevent the risk of fire or electric shock, install in a temperature and humidity controlled indoor area free of conductive contaminants. (Please see Technical Specifications section for acceptable temperature and humidity range.)
CAUTION! The product must be installed in a protected environment away from heat-emitting appliances such as a radiator or heat register. The location should provide adequate air flow around the product for proper ventilation.
CAUTION! To reduce the risk of injury, use cables come with the product. Use appropriate and certified external battery cables.
CAUTION! To reduce risk of damage and injury, use batteries with good quality.
CAUTION! Risk of electric shock. DO NOT remove the cover. No user serviceable parts inside.
CAUTION! Provide adequate ventilation for the battery compartment. The battery enclosure should be designed to prevent accumulation and concentration of hydrogen gas at the top of the compartment.
CAUTION! A battery can present a risk of electrical shock and high short circuit current. When working on batteries, remove watches, rings, or other metal objects. Use tools with insulated handles.
CAUTION! Hazardous live parts inside can be energized by the battery even when the AC input power is disconnected.
CAUTION! To avoid electrical shock, turn off the unit and unplug it from the AC power source before installing equipment or servicing the battery. Servicing the battery can only be performed by trained personnel.
DO NOT USE FOR MEDICAL OR LIFE SUPPORT EQUIPMENT! Do not use in any circumstance that would affect the operation and safety of life support equipment, medical applications, or patient care.
DO NOT USE WITH OR NEAR AQUARIUMS! To reduce the risk of fire or electric shock, do not use with or near an aquarium. Condensation from the aquarium can cause the unit to short out.
DO NOT USE THE PRODUCT ON ANY TRANSPORTATION! To reduce the risk of fire or electric shock, do not use the unit on any transportation such as airplanes or ships. The effect of shock or vibration caused during transit and the damp environment can cause the unit to short out.

2-3 Power Requirements of Your Equipment
-
Ensure that the equipment plugged into the AC outlet does not exceed the product's rated capacity (1200VA/900W for CPD1200EILCD). If rated unit capacities are exceeded, an overload condition may occur and cause the unit to shut down or the circuit breaker trip.
-
There are many factors that can affect the amount of power that your appliances will require. For optimal system performance keep the load below 80% of the unit's rated capacity.
2-4 Hardware Installation Guide
Step 1 Connect the Battery
For optimal battery life and reasonable recharging time, make sure the batteries capacity no less than 100Ah. Use batteries with same brand, type, and capacity.
Connect DC input cables of this product to external batteries:
Red “+” cable to the battery's Positive “+” polarity
Black “-” cable to the battery’s Negative “-” polarity
Single Battery Connection
Single battery voltage must be equal to DC voltage of the unit.

DC BreakerMultiple Batteries Connection – in Series
Connect two batteries in series can double the voltage. Sum of voltages must be equal to DC voltage of the unit.

Connect the product to a wall outlet. Charging the battery for at least 8 hours is recommended to ensure that the battery's maximum charge capacity is achieved. To recharge the battery and maintain optimal battery charge, simply leave the unit plugged into a wall outlet at all times. The battery can be charged whether the unit is turned on or off.
DO NOT connect Neutral of the Power Distribution Box to (a) the OUTPUT Neutral of this product, or (b) the INPUT Neutral of connected equipment. Otherwise, reversed polarity will damage the product and connected equipment.
