4.4 Operation procedure of external battery
Use the battery pack with voltage: 36VDC for 1kVA (12V
3
batteries), 48VDC for
C400R-020-B (C) (12V
4 batteries),
72VDC for C400R-030-B(C) (12V
6

Connection of batteries with more or less than the required cell
quantity will cause abnormal operation or permanent damage. One hard wiring
type battery terminal on the rear panel is used for connecting the battery pack.
The battery connection procedure is very important, any deviation from the
correct procedure may result in the risk of electric shock. Therefore the following
steps must be strictly complied with.
Make sure the mains input is off, if there is a battery breaker then turn it off first.
Remove the front panel, connect the battery via the Anderson PP45 connectors.
Prepare the battery cable which should be able to carry the current of >50A for
all models, the cross section area should be greater than 4 mm
2
for all model. And
battery wire colour is recommended as following:
+
GND
-
Red wire
Green/Yellow wire
Black wire
The red wire is connected to the "+" terminal of the battery. The black wire is
connected to the "-" terminal of the battery. (Note: the green/yellow wire is
grounded for protection purpose.)
Make sure the wires are fastened securely then install the terminal block cover
on the rear panel of the UPS.
Connect the UPS to the load. Then, turn on the mains switch or connect the power
cord of the UPS to utility power supply, the battery would start to be charged.
Caution:
A DC breaker must be connected between the UPS and external battery.
Caution:
