14) If it is necessary to connect the inductance load such as a
monitor or a laser printer to the UPS, the start-up power should
be used for calculating the capacity of the UPS, as its start-up
power consumption is too big to make the UPS which capacity
is small fail easily.
4.4 Operating Procedure For Connecting with The External
Battery (Only for “S” model)
1. The nominal DC voltage of external battery pack is 240VDC. Each
battery pack consists of 20 pieces of 12V maintenance free
batteries in series. To achieve longer backup time, it is possible to
connect multi-battery packs, but the principle of “same voltage,
same type” should be strictly followed.
2. For PowerWalker VFI 6000T LCD, select the UL1015
8AWG/6mm
2
respectively or other insulated wire which complies
with AWG Standard for the UPS battery wirings.
3. For PowerWalker VFI 10000T LCD, select the UL1015
6AWG/10mm
2
respectively or other insulated wire which complies
with AWG Standard for the UPS battery wirings.
4. The external battery pack must be independent for each UPS. It is
forbidden that two UPSs use same external battery pack.
5. The procedure of installing battery pack should be complied with
strictly. Otherwise it may encounter the hazardous of electric
shock.
1) Ensure the UPS is not powered on and the mains input
breaker is set in the “OFF” position.
2) A DC breaker must be installed between the external battery
pack and the UPS. The capacity of breaker must be not less
than the data specified in the general specification.
