GC330 Instruction Manual GC330 Instruction Manual POWER LED 1 2 3 4 UL2464 16AWGx4C 1000±50mm Standard male plug(power supply side): AMP 1-480702-0 equivalent PIN NO. OUTPUT 1,2 +V 3,4 -V Female plug(customer side, not provide with the power supply): AMP 1-480703-0 equivalent WARNING : Please make sure the polarity of the battery is connected correctly! Assembly Procedure : 1.Make sure the charger is shut off and cho osing suitable wire s to connect the ch arger and ba tteries based on the rati ng of charging current. The po larity must be correct: charger output (+) sho uld be connected to the (+) term inal of batte ries and charger output (-) should be conne cted to the ( -) terminal. In no times should the (+) an d (-) be short toget her or the charger and batteries will b e damaged. 2.Connect the AC input and check whether the op eration of LE D is correct. (red : cha rging ; green : batte ry is full) Note s On Operation: 1.The charg er sho uld be assembled in the place with go od ventilatio n and low moisture . Exp osure to the rain or snow is strictly prohibite d. 2.Wires con nectin g between the cha rger and batteries should be as short as possible s ince the high voltage drop on th e wires will increase the time required to fully c harge the batteries. 3.Make sure the charging voltage an d char ging current are suitable for the batte ries you are using. 4.If th e batt eries n eed to connect in series for cha rging , old ba tterie s are not suggested to be used with ne w ones or th e lifeti me of bat teries may re duce because of the unbalance charg ing voltage distribution o n new and o ld batteries. 5.Please tu rn off the cha rger before conne cting or disconnecting the wires . 6.The charg er has a 2-year worldwide warranty, howev er, damages from misusin g the charge r will not be included in the cov erage of warranty. 1 Statu s Under General Opera tion: At the begin ning s tage of operation, the charger provides the largest current with 40.8V dc of output voltag e (for 36V batterie s) to charg e batt eries. The LED indicator will lighten in red. After a period of time (probably a coup le of hours, based on the capac ity of batte ries), the cha rging curren t will d ecrease gradually. After reaching 0.3A±0.1A of its maximum value, the charger will go into "floating-charge" stage. The LED ind icator will turn to green. The relationship between charg ing current and cha rging voltage for each opera tion s tage are shown in t he cur ves below : (V,I) Stage 1 Stage 2 Constant Current Area Constant Voltage Area V Fast Charging 0.3A±0.1A Float Charging Red Color of LED I TIME Green Ch argin g Curr ent An d Am bient Tempe rature 100 80 60 50 40 20 -3 0 0 10 20 30 40 50 60 7 0 (HORIZONTAL ) EXTERNAL CASE TEMPERATU RE (℃) Su ggested Ba ttery Capac ity: 1.It will n ot hav e any problem if the capacity of batteries larger than the sugges ted value.

CAREFULLY FOLLOW THESE INSTRUCTIONS. 1.Thi s manual contains important sa fety and operating instructions for battery c harger Models GC2 20A12,GC2 20A24 and GC220A48. 2. SAVE THESE IN STRUCTIONS - This ma nual contains important safety a nd op erating Instructions for battery charge r Models GC330A36 and GC330A48. 3.Before using ba ttery c harger, read all ins tructions an d cautionary markings on batter y char ger, battery, and product using battery. 4.CAUTION - To reduce risk of injury, cha rge on ly one, 12V L ead-Acid ty pe rec hargea ble ba tteries , which were conn ected in series, for Mode l GC3 30A36; charge only four, 12V L ead-Acid type rechargeable batteries, which were connected in series, for Model GC330A48. 5.Power Supply Cord: Power Su pply Cord - Cord Type SJT or SVT, rated min imum 105℃, No. 18AWG/3C,provided with a molded-on, groun ding type atta chme nt plug with a 15A, 125V(NEMA 5-15p ) configurati on and a molded-o n connector which mates with th e appliance inlet, minimum 1.8m and ma ximum 3m in length. 6. The equip ment was investigated under 20 amperes branch circuit in accordan ce with the National Electrical Code, ANSI/NFPA 70, to reduce th e risk of fire, connect only a circuit provided with 20 amperes maximum bra nch over current protectio n. 3
