equipment (WEEE) in the trash. For proper disposal, contact your local recycling/reuse
or hazardous waste center.
Information, advice, help.
Refer to the user manual.

Safety of persons
RISK OF VOLTAGE BACKFEED. The system has its own power source (the battery). Isolate
the UPS and check for hazardous voltage upstream and downstream during lockout-
tagout operation. Terminal blocks may be energized even if the system is disconnected
from the AC power source.
Dangerous voltage levels are present within the system. It should be opened exclusively
by qualified service personnel.
The system must be properly grounded.
The battery supplied with the system contains small amounts of toxic materials. To avoid
accidents, the directives listed below must be observed:
- Servicing of batteries should be performed or supervised by personnel knowledgeable
about batteries and the required precautions.
- When replacing batteries, replace with the same type and number of batteries or
battery packs.
-Do not dispose of batteries in a fire. The batteries may explode.
- Batteries constitute a danger (electrical shock, burns). The short-circuit current may
be very high.
Precautions must be taken for all handling:
- Wear rubber gloves and boots.
- Do not lay tools or metal parts on top of batteries.
- Disconnect charging source prior to connecting or disconnecting battery terminals.
- Determine if battery is inadvertently grounded. If inadvertently grounded, remove
source from ground. Contact with any part of a grounded battery can result in
electrical shock. The likelihood of such shock can be reduced if such grounds are
removed during installation and maintenance (applicable to equipment and remote
battery supplies not having a grounded supply circuit).
Product safety
The UPS connection instructions and operation described in the manual must be followed
in the indicated order.
CAUTION - To reduce the risk of fire, the unit connects only to a circuit provided with
branch circuit overcurrent protection for :
63A rating, for 6kVA models,
100A rating, for 10kVA models
•The upstream circuit breaker for Normal AC/Bypass AC must be easily accessible. The unit
can be disconnected from AC power source by opening this circuit breaker.
An additional AC contactor is used for backfeed protection and must comply with IEC/EN
62040-1 (the creep age and clearance distances shall meet the basic insulation
requirements for pollution degree 2).

Disconnection and overcurrent protection devices shall be provided by others for
permanently connected AC input (Normal AC/Bypass AC) and AC output circuits.
Check that the indications on the rating plate correspond to your AC powered system and
to the actual electrical consumption of all the equipment to be connected to the system.
For PLUGGABLE EQUIPMENT, the socket-outlet shall be installed near the equipment and
shall be easily accessible
Never install the system near liquids or in an excessively damp environment.
Never let a foreign body penetrate inside the system.
Never block the ventilation grates of the system.
Never expose the system to direct sunlight or source of heat.
If the system must be stored prior to installation, storage must be in a dry place.
The admissible storage temperature range is -25°C to +60°C with battery(-15°C to +40°C
without battery).
Special precautions
The unit is heavy: wear safety shoes and use vacuum lifter preferentially for handling
operations.
All handling operations will require at least two people (unpacking, lifting, installation).
Before and after the installation, if the UPS remains de-energized for a long period, the
UPS must be energized for a period of 24 hours, at least once every 6 months (for a normal
storage temperature less than 25°C). This charges the battery, thus avoiding possible
irreversible damage.
During the replacement of the Battery Module, it is imperative to use the same type and
number of element as the original Battery Module provided with the UPS to maintain an
identical level of performance and safety.

1.2 Electronic equipment protection
The uninterruptible power system (UPS) protects your sensitive electronic equipment
from the most common power problems, including power failures, power sags, power
surges, brownouts, line noise, high voltage spikes, frequency variations, switching
transients, and harmonic distortion.
Power outages may occur unexpected, and the power quality will be erratic. These power
problems have the potential to corrupt critical data, destroy unsaved work sessions, and
damage hardware - causing hours of lost productivity and expensive repairs.
With the UPS, you can safely eliminate the effects of power disturbances and guard the

7
integrity of your equipment. Providing outstanding performance and reliability, UPS’s
unique benefits include:
True online double-conversion technology with high power density, utility
frequency independence, and generator compatibility.
Selectable High Efficiency mode of operation.
Standard communication options: one RS232 communication port, one USB
communication port, one dry in port and dry out port.
Optional connectivity cards with enhanced communication capabilities.
Firmware that is easily upgradable without a service call.

AC Contactor: 208-240V, 63A (6 kVA)
208-240V, 100A (10 kVA)
3.4.2 Wiring for AC Cable (AC source to UPS)
High leakage current:
Earth connection essential before connecting supply.
Common input/output sources connection.
This type of connection must be carried out by qualified electrical person.
Before carrying out any connection, check that the upstream protection devices
(Normal AC source and Bypass AC source) are open "O" (Off).
Always connect the ground wire first.

16
Layout of terminal block(TB) of the UPS:
Note:
1. AC INPUT: UPS input TB (L/N, PE is screw)
2. AC OUTPUT: UPS output TB (L1/L2/N1/N2, PE is screw)
3. PARA JUMPER: For UPS’s parallel installation (JP1/JP2)
Below will introduce 3 modes (Default is ‘LV mode-1’) of wiring application for UPS
input/output, please select one mode for your actual application.
LV mode-1
Short UPS output terminal ‘L1/L2’ and ‘N1/N2’ with ‘busbar’, then connect AC cable.

17
LV mode-2
Each 120V output only can take half an UPS rating.
HV mode
Short UPS input terminal ‘L2/N1’ with ‘busbar’, then connect AC cable.
For the cable well fixed, it is recommended to tie these cables to the convex of rear-
panel.

18
3.4.3 Wiring with external battery modular (EBM) (DC source to UPS)
1. Be sure to disconnect the battery cable from the EBM before connecting the battery
terminals of the UPS
2. Make sure the UPS is completely off before connecting or disconnecting the EBM.
3. Before connecting the EBM, make sure that the number of battery sections and
capacity are the same as LCD setting.
4. Do not reverse the polarity of the external battery.
•Connect with user’s own EBM:
Connect EBM to UPS with ‘Battery cable’ (optional configured).
Note:
1. If additional battery cable needed for installation, it must follow cable specification
and the maximum length of battery cable 10 meters for application.
2. If a length of battery cable over 10 meters requests, please contact
distributors/agents for details.

19
•Connect with the configured EBM:
Note:
1. Extended runtime with up to 6 Extended Battery Modules (EBMs) per UPS.
2. Extend more than 2 EBMs, additional ground wires 10mm^2 cross-sectional area)
are require.

20
4Parallel system Installation and Operation(Optional)
If your UPS is configured with parallel function, up to 3 UPSs can be connected in parallel to
configure a sharing and redundant output power.
In parallel system, the mechanical installation for each modular is same as the single system.
Details please refer to Chapter 3.3.
Parallel system AC cable diagram:
4.1 Wiring for AC Cable
1. Wiring length requirement:
When the distance between the load and the parallel UPS is less than 10 meters, the
length difference between the input/output lines between the UPSs in the parallel
system is less than 20%.
When the distance between the load and the parallel UPS is greater than 20 meters,
the length difference between the input/output lines between the UPSs in the
parallel system is less than 5%.
2. In the parallel system, common battery application is not supported. independent
EBM connect to each UPS, please refer to chapter 3.4.3.
3. Professional installation is required, please set the parallel system in the restricted
area!
