External Battery Cabinet Connection Precautions

Battery
1. Charge Voltage
2. Charge Current
Only use the same type of batteries from the same supplier. Never use old, new and differ-
ent Ah batteries at the same time.
The number of batteries must meet UPS requirements.
Do not connect the batteries in reverse.
Use the voltage meter to measure whether the total voltage, after the external battery cabi-
net connection, is around 12.5Vdc × the total number of batteries.
To extend battery backup time, you can connect several external battery cabinets to the
UPS. Please note that the number of the batteries in each paralleled external battery cabi-
net must be the same.
