General Precautins Befre using it, read all instructins and markings: (1) inverter (2) battery (3) user manual CAUTION: 1. T reduce risk f injury, charge nly lead-acid rechargeable batteries. If custmer use flded batteries, batteries must be maintained regularly. Other battery types may cause damage and injury. 2. D nt expse it t rain, snw r any type liquids. Inverters are designed fr indr use. 3. D nt disassemble it. Take it t qualified service center when service r repair is needed. 4. T prevent the risk f electric shck, discnnect all wiring befre attempting any maintenance r cleaning. Only turning ff the unit will nt reduce the risk. WARNING: 1. Prvide ventilatin frm the battery cmpartment t utdrs. The battery enclsure shuld be designed t prevent accumulatin and cncentratin f hydrgen gas at the tp f the cmpartment. 2. NEVER charge a frzen battery and cnnect such 12V/24V/48V batteries t inverter. 3. Input/utput AC wiring mustn t be less than 12AWG and nt rated fr 75 C r higher. Battery cable mustn t be rated fr 75 C r higher and shuld be n less than 4AWG /6AWG gauge. 4. Pay special attentin when wrking with metal tls arund batteries. Batteries shrt-circuiting culd cause an explsin. 5. Read the battery installatin and maintenance instructins carefully befre perating. Persnnel Precautins 1. Better t prepare plenty f fresh water and sap nearby in case battery acid cntacts skin, clthing r eyes. 2. Avid tuching eyes while wrking near batteries. 3. NEVER smke r allw a spark r flame near batteries. 4. Remve persnal metal items such as rings, bracelets, necklaces, and watches when wrking with batteries. Batteries may prvide heavy shrt-circuit current, which wuld be enugh t make metal melt and causes severe burn. 5. If a remte r autmatic generatr start system is used, disable the autmatic starting circuit r discnnect the generatr t prevent accident during servicing -1- -16-
