1. SAFETY
>>Battery
DANGER! - Beware, lead-acid batteries generate explosive gases during normal battery operation.

 Wash with soap and water immediately if battery acid contacts skin or clothing. If acid enters eye, flush immediately with cool,clean running
water for at least 15 minutes and seek immediate medical attention.
 DO NOT smoke or allow a spark or flame in the vicinity of the battery or engine.
 If the battery terminals are corroded or dirty, clean them before attaching the leads.
WARNING! To prevent the risk of sparking, short circuit and possible explosion DO NOT drop metal tools in the battery area, or allow them to

touch the battery terminals.
 Before attaching to battery, remove personal metallic items such as rings, bracelets, necklaces and watches. A lead acid battery can produce
a short-circuit current which is high enough to weld such items and cause severe burns.
>>Inverter/Charger
DO NOT expose inverter to rain, snow, spray, bilge or dust. DO NOT cover or obstruct ventilations.

MAKE SURE at least 10CM of clearance on DC terminal side and rear heat dissipation side, and 3CM of clearance on body side for air flow.

MAKE SURE existing wiring is in good electrical condition. DO NOT operate inverter charger with damaged or substandard wiring.

DO NOT install in compartments containing batteries or flammable materials or in locations which require ignition protected equipment.

DO NOT disassemble this inverter charger. Internal capacitors remain charged after all power is disconnected. Attempting to service this

inverter charger by yourself may cause electrical shock or fire.
WARNING! Disconnect both AC and DC power from the inverter charger before any maintenance. Turning off controls will not reduce risk.

DANGER! The output side of inverter's AC wiring at no time be no connected to public power or a generator. Beware the wiring connection.

2. INTRODUCTION
>>General Information
This pure sine wave inverter charger is the combination of inverter, battery charger and AC autotranser switch. This complete system with a peak
conversion efficiency of 88%.
CPT is a inverter charger with backup UPS function. When utility AC power cuts off, the transfer relay is de-enegizered and the load is transferred
to inverter ouput. Once the qualified AC utility power is restored, the relay will be energized and the load is automatically reconnected to AC utility.
This inverter charger unit is easily customized to battery priority via a DIP switch which helps extract maximum power from battery in renewable
energy systems. Therefore this inverter charger is suitable for renewable energy system, RV, marnine and emergency appliances.
3. SPECIFICATION
