⚫ A usermanual
⚫ A communicationcable
⚫ A battery cable (for Plus III-6KLRB/PlusIII-10KLRBonly)
2) Inspect the appearance of the UPS to see if there is any damage during
transportation. Do not turn on the unit and notify the carrier and dealer
immediately if there is any damage or lacking of some parts.

3.4 Input and output power cords and protective earth ground installation
1. Notes for installation
1) The UPS must be installed in a location with good ventilation, far away from water,
inflammable gas and corrosive agents.
2) Ensure the air vents on the front and rear of the UPS are notblocked. Allow at least
0.5m of space on each side.
3) Condensation to water drops may occur if the UPS is unpacked in a very low
temperature environment. In this case it is necessary to wait until t he UPS is fully dried
inside out before proceeding installation and use. Otherwise there are hazards of
electric shock.
2. Installation
Installation and wiring must be performed in accordance with the local electric code and
the following instructions by professional personnel.
For safety, please cut off the mains power switch before installation. The battery breaker
also needs to be cut off if it is a long backup time model.
1) Open the terminal block cover located on the rear panel of theUPS, please refer
to the appearance diagram.
2) For Plus III-6KLRB UPS, it is recommended to select the UL1015 10AWG(6mm2)
wire or other insulated wire which complies with AWG Standard for the UPS input
and output wirings.
3) For PlusIII-10KLRB, it is recommended to select the UL1015 8AWG(10mm2) wireor
other insulated wire which complies with AWG Standard for the UPS input and output
wirings
Note: Do not use the wall receptacle as the input power source for the UPS, as its
rated current is less than the UPS’s maximum input current. Otherwise the
receptacle may be burned and destroyed.
4) Connect the input and output wires to the corresponding input and output
terminals according to the following diagram.

I) Input/Output: 1P2W+G 220V or 230V or 240V
II) Input: 1P2W+G 220V or 230V or 240V, Output: 1P3W+G 110/220V or 115/230V
or 120/240V, With Isolation Transformer
‧Connection for dual Output: 110/220V or 115/230V or 120/240V
•Connection for single output 110V or 115V or 120V
Note: you must make sure that the input and output wires and the input and output
terminals are connected tightly.

5) The protective earthground wire refers tothe wire connectionbetween the equipment which
consumes electric equipmentand the ground wire. The wire diameterof protective earthground
wire should be at least as above mentioned for each model and green wire or green wire with
yellow ribbonwire is used.
6) After having completed the installation, make sure the wiring is correct.
7) Please install the leak current protective breaker at the output power distributionpanelof the
UPS if necessary.
8) To connect the load with the UPS, please turn off all the loads first, then perform the
connection and finally turn on the loads one by one.
9) No matter the UPS is connected to the utility power or not, the output of the UPS may have
electricity. The parts inside the unit may still havehazardous voltage after turning off the UPS.
To make the UPS have nooutput, power off the UPS, and then disconnect the utility power
supply.
10 )Suggest charging the batteries for 8 hours before use. After connection, turn the
inputbreaker in the “ON” position, the UPS will charge the batteries automatically. You
can also use the UPS immediately without charging the batteries first, but the backup
time may be less than the standard value.
11)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 when it is started.
•Important notes: If the UPS is used in single mode, JPI and JP2 must be connected
by 10AWG(6mm2). If the UPS is used in parallel mode, the Jumper between JP1 and
JP2 mustbe removed.
3.5 Operating procedure for connecting the long backup time model UPS with the
external battery
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 theprinciple of “same voltage, same type”

should be strictly followed.
2. The connector of the external battery cable is used to plug into the externalbattery socket
of the UPS, the other end of the external battery cable is madeof three open wires with ring
terminals to connect with the external battery pack(s). The procedure of installing battery
bank should be complied with strictly.Otherwise you may encounter the hazardous of
electric shock.
1) A DC breaker must be connected between the battery pack and theUPS. The capacity
of breaker must be not less than the data specified in the general specification.
2) Set the battery pack breaker in “OFF” position and connect the 20 pieces of batteries
in series.
3) Youmust connect the external battery cable to the battery first, if you connect the cable
to the UPS first, you may encounter the hazardous of electric shock. The positive pole
of the battery is connected to the 10KE in parallel with blue and brown wires; the
negative pole of the battery is connected to the 10KE in parallel with black and white
wires; thegreenand yellowribbon wire is connected tothe ground of the batterycabinet.
3. To complete the connection by plugging the connector of the external battery cable into
the external battery socket of the UPS. Do not attempt to connect any loads to the UPS
now. You should connect the input power wire to the right position first. And then set the
breaker of the battery pack in the ON position. After that set the input breaker in the ON
position.
The UPS begins to charge the battery packs at the time.
3.6 EPO Connection
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.
2. The connection
Normally the EPO connector is closed with a wire on the rear panel, which is supplied
in the accessory. Once the connector is open, the UPS would stop the output and
enter EPO status.
