5. Connecting the Batteries
NOTE: Ensure battery breaker is turned open / off.
Connect four 12VDC batteries in series for a total of 48VDC.
6. Install and Connect the Temperature Probe
NOTE: Batteries are adversely affected by heat; the Temperature
Probe provides feedback to control the cooling system. The Battery
Temp Probe connector must be plugged into the UPS for it to function.
IMPORTANT: Because it is easy to overlook, an unconnected
Temperature Probe is the main reason that the red Alarm LED comes
ON when power is applied.
1. Attach the Temperature Probe to the battery that you expect will be
exposed to the most heat—for example, the battery next to the wall of
the cabinet where you expect to have the most exposure to the sun.
NOTE: Connect the ring lug connector of the Temperature Probe to
the battery terminal.
2. Connect the supplied 10-foot extension cable to the Temperature
Probe and route it to the UPS.
