User’s Manual
If an extension cord is necessary, it must be a 3-conductor, No. 14 AWG minimum, heavy-duty cord with
ground. It must also be in good electrical condition and as short as possible, 50 ft (15m) maximum. Make
sure that the pins on the plug of the extension cord are the same number, size, and shape as the AC power
cord plug on the charger. The use of an improper extension cord could result in a risk of fire or electrical
shock.
Locate all cords so that they will not be stepped on, tripped over, or otherwise subjected to damage, stress, or
accidentally disconnected.
CAUTION: VERIFY THAT THE AC POWER CORD IS FULLY ENGAGED IN THE IEC INLET AND
CANNOT BE PULLED LOOSE BEFORE USING THE CHARGER.
DANGER: RISK OF ELECTRIC SHOCK! CONNECT THE AC SUPPLY CORD DIRECTLY TO A
GROUNDED, 3-WIRE OUTLET. DO NOT TOUCH UNINSULATED PORTION OF DC OUTPUT TERMINALS
OR BATTERY TERMINALS. REPLACE DEFECTIVE CORDS, WIRES, OR CONNECTORS IMMEDIATELY.
7. DC OUTPUT
WARNING: LEAD-ACID BATTERIES GENERATE EXPLOSIVE GAS. CHARGE ONLY IN WELL
VENTILATED AREAS. TO PREVENT ARCING OR BURNING NEAR BATTERIES, DO NOT DISCONNECT
THE DC CHARGING CONNECTOR(S) FROM THE BATTERIES WHEN THE CHARGER IS OPERATING.
IF THE CHARGE CYCLE MUST BE INTERRUPTED, UNPLUG THE AC POWER CORD BEFORE
DISCONNECTING THE DC OUTPUT CONNECTOR(S) FROM THE BATTERIES. KEEP SPARKS, FLAME,
AND SMOKING MATERIALS AWAY FROM BATTERIES. TO REDUCE THE RISK OF FIRE, DO NOT USE
THE CHARGER NEAR FLAMMABLE MATERIALS OR VAPORS.
Only charge batteries of the same type, voltage, number of cells, and amp-hour capacities listed on the
charger ratings label.
The charger includes externally accessible screw terminals for the DC output (see Figure 5-1). When
connecting a cordset or wire assembly to the DC output screw terminals, ensure that the other end of the
cordset or wire assembly is disconnected. The screw terminals should be torqued to 8.8 in-lbs.
The “+”
marked screw terminal must be connected to battery positive (+). The “-“ marked screw terminal must be
connected to battery negative (-). The charger will not operate if the polarity is reversed.
If the charger had a DC output cordset installed in the factory, the DC output cordset includes a commonly-
used connector/plug. The polarity of the charger DC output connector/plug must be the same as the battery
connector. The BLACK DC cable must be connected to the battery negative (-), and the WHITE or RED DC
cable must be connected to the battery positive (+). The charger will not operate if the polarity is reversed.
