CONNECTING THE BACKUP BATTERY
The G4LC32ISA-LT uses a RAM backup battery. This 3.6-volt lithium battery features a shelf life of up
to 10 years and an operational life of two to five years.
To maintain operational life, the battery is not connected at the factory. Attach the battery connector
to the battery terminal labeled J1. The connection is keyed and will attach in one direction only, with
the red wire connecting to the positive lead. Refer to Figure 3-6 for the battery connection locations.
(Execute the following steps only after setting the configuration jumpers. Refer to the next section on
the following page for G4LC32ISA-LT installation instructions.) After installing the G4LC32ISA-LT in
the PC, attach the Velcro strip to a convenient location inside the computer. Secure the battery to the
Velcro strip.
Figure 3-6: G4LC32ISA-LT Backup Battery
The Battery Service Record stamp should be placed in a convenient place in the computer. It includes
the Opto 22 part number of the battery (G4BATT32), the date the battery was installed, and the date
the battery should be replaced (five years after installation). If the G4LC32ISA-LT is subjected to
temperature extremes, the battery may require replacement after as little as two years.
