11. If there is breaker on battery cabinet, switch it “ON”.
12. Check if there is appropriate battery voltages to the battery input terminals by proper
measuring device.

External battery cable selection is determined by application. Fuses which are recommended for
UPS and battery cabinet are given. To connect to these type fuses, the lowest diameter cables are
suggested. Please, refer to standard called EN 50525-2-31(VDE 0100-430) in this subject. The
selection should be such that the cable will allow at most 0.5 Vdc decreasing.

"External Battery Temperature Measurement Kit" is used for optimization according to battery
temperatures, batteries use is optimized according to temperature.

The external battery connection diagram is given below.
