Notes: 1) If the UPS is used in single mode, JP1 and JP2 must be
connected. If the UPS is used in parallel mode, the Jumper between
JP1 and JP2 must be removed.
2) Battery+/- connection is only for “S”model.
10) Install an output breaker between the output terminal of UPS
and the load, and the breaker should with leakage current
protective function if necessary.
11) Turn off all the loads first before connecting the load with the
UPS, then perform the connection and finally turn on the loads
one by one.
12) After completing the installation, check all the wires is
connected correctly and tightly.
13) Suggest charging the batteries for 8 hours before use. After
installation, turn on the mains power switch and turn the input
breaker in the “ON” position, the UPS will charge the batteries
automatically. It can also use the UPS immediately without
charging the batteries, but the backup time may be less than the
standard value.

16
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/6mm2respectively or other insulated wire which complies
with AWG Standard for the UPS battery wirings.
3. For PowerWalker VFI 10000T LCD, select the UL1015
6AWG/10mm2respectively 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.

17
3) Set the external battery pack breaker in “OFF” position and
connect the 20 pieces of batteries in series.
4) Connect the external battery pack to the battery terminals.
Check the polarity of connection is correct.
5) Set the breaker of the battery pack in the “ON” position.
6) Set the mains input breaker in the “ON” position, the UPS
would power on and start to charge the battery pack.
4.5 EPO Connection
4.5.1 Introduction
Emergency power off function which the UPS supplies is, when the
emergency occurs, such as the failure of load, the UPS can cut off
the output at once by operating the EPO port manually.
4.5.2 The connection
Normally the EPO connector is opened without any connection on
the rear panel. Once the connector is closed with a wire, the UPS
would stop the output and enter EPO status.
Enable the EPO status Disable the EPO status
Fig. 4-8 Default EPO status
To recover to normal status, first EPO connector should be opened,
and enter LCD menu (illustrated in the chapter of 5.4.5) to clear
EPO status, then UPS would stop alarm and recover to Bypass
model.And UPS needs be turned on by manual operation.
The polarity of connector could be inversed by setting in LCD menu
in the chapter of 5.4.7. Contact your local distributor for further
information before modifying the settings.
