1. Brief Introduction
The Online EX Series is an uninterruptible power supply incorporating
double-conversion technology, optional EPO and maintenance switch,
parallel redundancy. It provides perfect protection specifically for computer
equipment, communication systems and computerized instruments.
Its true online double-conversion design eliminates all mains power
disturbances. A rectifier converts the alternating current from the utility
power to direct current. This direct current charges the batteries and
powers the inverter. On the basis of this DC voltage, the inverter
generates a pure sinusoidal AC voltage, which is constantly powering the
loads.
In the event of power failure, the maintenance-free batteries power the
inverter. If overload or inverter failure, UPS will work on bypass mode to
power with mains power. After load become normal, it will still work on
battery mode.

2. Set the battery pack breaker in “OFF” position and connect the 16
pieces of batteries in series, select proper battery wire to connect batteries
and UPS (refer to 2.2 wiring table).
Dangerous: You must connect the external battery cable to the battery
first, if you connect the cable to the UPS first, you may encounter the

13
hazardous of electric shock.
3. To complete the connection by connecting the external battery cable
with corresponding terminal on terminal block of the UPS. Do not attempt
to connect any load 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 mains input protective breaker in
the “ON” position. The UPS begins to charge the battery packs at the time.
Note: The battery protective earth ground of UPS is case ground on
the right of terminal block of UPS, The symbol is .
2.5 Connect to Computer interface

2.6 Parallel Card (Optional Accessory)
1. Brief introduction of the redundancy
N+X is currently the most reliable power supply structure. N represents
the minimum UPS number that the total load needs; X represents the
redundant UPS number. The bigger the X is, the higher reliability of the
power system is. For occasions where reliability is highly depended on,
N+X is the optimal mode.
2. Parallel installation
Parallel function is a selectable function, user can buy parallel
function component (consist of parallel card and parallel cable)
then install by professional service person, the maximum
parallel quantity is 3 pieces, N UPS should be supplied by N
battery packs respectively,
1) Take down the parallel cover, connect the parallel cable:
Parallel card is the communication interface between UPSs
in parallel, connect parallel cable between UPSs in parallel
through parallel card

2) Connect the output wires of each UPS to an output breaker panel,
and then connect from output breaker panel to load.
Note:
The requirement of the output wiring is as following:
When the distance between the UPSs in parallel and the breaker panel
is less than 20 meters, the difference between the wires of input & output
of the UPSs is required to be less than 20%;
When the distance between the UPSs in parallel and the breaker panel
is greater than 20 meters, the difference between the wires of input &
output of the UPSs is required to be less than 10%.
3) UPS in parallel wiring diagram shows as below, the wiring of every
