Check to ensure that the external batteries you |
|
| |||||
are connecting match the voltage listed on your |
|
| |||||
UPS’s battery connector. Plug either end of the |
|
| |||||
battery connection cable (supplied with the |
|
| |||||
battery pack) into the UPS’s External Battery |
|
| |||||
Connector and the other end into the Battery |
| 48V/26A | |||||
|
| ||||||
Output Connector on the rear panel of the |
|
| |||||
external battery pack. |
|
|
|
| |||
Since your UPS has internal batteries, external |
|
| |||||
batteries are only needed to extend runtime. |
|
| |||||
Adding | external | batteries | will | increase | 2 | SU2200RTXL2U shown | |
recharge time as well as runtime. Make sure | |||||||
|
| ||||||
that each end of the cable is fully inserted into |
|
| |||||
its connector. Several small sparks may result |
|
| |||||
during battery connection; this is normal. |
