Installation & Safety Installation • A wire loop provides for selection of battery types: flooded (Wet) type (do not cut the wire loop), sealed (AGM, Dry) and gel type (cut the wire loop and tape the wire ends back with electricians tape). •... - Page 6 Installation & Safety - cont. rating of the extension cable and meet all national and local electrical code • requirements. When attaching leads to battery terminals, be careful that tools do not short between battery terminals. Shorting between battery terminals may cause extreme arcing resulting in explosion or extreme heat that can cause burns.

Operation (1) Make sure the yellow wire loop is prepared for the correct battery type. Flooded (wire loop not cut), sealed AGM and Gel (wire loop cut) (2) Connect the charger AC cable into a single phase AC socket with a nominal voltage rating of 100V, 110V, 115V, 120V, 220V, 230V, or 240V and a frequency rating of 50 or 60Hz. -
Page 8: Maintenance
Maintenance WARNING: Disconnect from AC voltage before doing any service. When plugged-in the AC wiring is an electric shock hazard. Disconnecting the DC output (connection to battery) near the batteries when the charger is ON may cause the batteries to explode resulting in serious injury or death. WARNING: Risk of an electric shock causing serious injury or death. - Page 9 LED Table for Troubleshooting Yellow Green #1 Green #2 Status Case 1 Normal Condition: AC Power is not connected to the charger.

Troubleshooting - cont. BATTERIES DO NOT FULLY CHARGE If the batteries are charged overnight, make sure the AC supply is not being switched- off at night with other building items. NEW BATTERIES If batteries are new they sometimes need 20 to 30 charge/discharge cycles before they charge normally due to a process called plate formation.
