1. Safety and EMC instructions

Please read carefully the following user manual and the safety instructions before installing the unit or using
the unit!

1-1. Transportation and Storage

Please transport the UPS system only in the original package to protect against shock and

impact.

The UPS must be stored in the room where it is ventilated and dry.

1-2. Preparation

Condensation may occur if the UPS system is moved directly from cold to warm environment.
The UPS system must be absolutely dry before being installed. Please allow at least two hours for the
UPS system to acclimate the environment.

Do not install the UPS system near water or in moist environments.

Do not install the UPS system where it would be exposed to direct sunlight or nearby heater.

Do not block ventilation holes in the UPS housing.

1-3. Installation

Do not connect appliances or devices which would overload the UPS (e.g. big motor-type
equipment)) to the UPS output sockets or terminal.

Place cables in such a way that no one can step on or trip over them.

Do not block air vents in the housing of UPS. The UPS must be installed in a location with good
ventilation. Ensure enough space on each side for ventilation.

UPS has provided earthed terminal, in the final installed system configuration, equipotential
earth bonding to the external UPS battery cabinets.

The UPS can be installed only by qualified maintenance personnel.

An appropriate disconnect device as short-circuit backup protection should be provided in the
building wiring installation.

An integral single emergency switching device which prevents further supply to the load by the
UPS in any mode of operation should be provided in the building wiring installation.

Connect the earth before connecting to the building wiring terminal.

Installation and Wiring must be performed in accordance with the local electrical laws and
regulations.

1-4. Operation

Do not disconnect the earth conductor cable on the UPS or the building wiring terminals in any
time since this would cancel the protective earth of the UPS system and of all connected loads.

The UPS system features its own, internal current source (batteries). The UPS output sockets or
output terminal blocks may be electrically live even if the UPS system is not connected to the building
wiring outlet.

In order to fully disconnect the UPS system, first press the “OFF” button and then disconnect
the mains.

Ensure that no liquid or other foreign objects can enter into the UPS system.

The UPS can be operated by any individuals with no previous experience.

2. Installation and Operation

There are two kinds of case: Tower and Rack. “6K” means 6K tower model and “6KRM” means 6K rack
model. Parallel function is also available for these two types and related installation and operation of Parallel
function will be described in detail in the following content.

2-1. Unpacking and Inspection

Unpack the package and check the package contents. The shipping package contains:

 One UPS
 One user manual
 One monitoring software CD
 One RS-232 cable (option)
 One USB cable
 One parallel cable (only available for parallel model)
 One share current cable (only available for parallel model)
 One battery cable (option)

NOTE: Before installation, please inspect the unit. Be sure that nothing inside the package is damaged
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. Please keep the original package in a safe place for future use.

2-3. Single UPS Installation

Installation and wiring must be performed in accordance with the local electric laws/regulations and execute
the following instructions by professional personnel.

1) Make sure the mains wire and breakers in the building are enough for the rated capacity of UPS to
avoid the hazards of electric shock or fire.

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.

2) Switch off the mains switch in the building before installation.

3) Turn off all the connected devices before connecting to the UPS.

4) Prepare wires based on the following table:

NOTE 1: The cable for 6K/6KL should be able to withstand over 40A current. It is recommended to
use 10AWG or thicker wire for safety and efficiency.

NOTE 2: The cable for 10K/10KL should be able to withstand over 63A current. It is recommended to
use 8AWG or thicker wire for safety and efficiency.

NOTE 3: The selections for color of wires should be followed by the local electrical laws and
regulations.

5) Remove the terminal block cover on the rear panel of UPS. Then connect the wires according to the
following terminal block diagrams: (Connect the earth wire first when making wire connection. Disconnect
the earth wire last when making wire disconnection!)

Terminal Block wiring diagram for rack models

NOTE 1: Make sure that the wires are connected tightly with the terminals.

NOTE 2: There are two kinds of outputs: output terminal/outlets and programmable terminal. Please

connect non-critical devices to the programmable terminal and critical devices to the output terminal/outlets.
During power failure, you may extend the backup time to critical devices by setting shorter backup time for
non-critical devices.

NOTE 3: Please install the output breaker between the output terminal and the load, and the breaker
should be qualified with leakage current protective function if necessary.

6) Put the terminal block cover back to the rear panel of the UPS.

Warning: (Only for standard model)

 Make sure the UPS is not turned on before installation. The UPS should not be turned on during wiring

connection.

Particularly, do not try to connect the standard internal battery to the external battery. The battery type

and voltage may be different. If you connect them together, it maybe causes the hazard of electric
shock or fire!

Warning:

 For standard battery pack, there are one DC breaker to disconnect the battery pack and the UPS. But

for other external battery pack, make sure a DC breaker or other protection device between UPS and
external battery pack is installed. If not, please install it carefully. Switch off the battery breaker before
installation.

NOTE: Set the battery pack breaker in “OFF” position and then install the battery pack.

 Pay highly attention to the rated battery voltage marked on the rear panel. If you want to change the

numbers of the battery pack, please make sure you modify the setting simultaneously. The connection
with wrong battery voltage may cause permanent damage of the UPS. Make sure the voltage of the
battery pack is correct.

 Pay highly attention to the polarity marking on external battery terminal block, and make sure the

correct battery polarity is connected. Wrong connection may cause permanent damage of the UPS.

 Make sure the protective earth ground wiring is correct. The wire current spec, color, position,

connection and conductance reliability should be checked carefully.

 Make sure the utility input & output wiring is correct. The wire current spec, color, position, connection

and conductance reliability should be checked carefully. Make sure the L/N site is correct, not reverse
and short-circuited.
