1. Important Safety Warning

Please comply with all warnings and operating instructions in this manual strictly. Save this
manual properly and read carefully the following instructions before installing the unit. Do not
operate this unit before reading through all safety information and operating instructions
carefully.

1-1. Transportation

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

and impact.

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 near

heater.

 Do not block ventilation holes in the UPS housing.

1-3. Installation

 Do not connect appliances or devices which would overload the UPS system (e.g.

laser printers) to the UPS output sockets.

 Place cables in such a way that no one can step on or trip over them.
 Do not connect domestic appliances such as hair dryers to UPS output sockets.
 The UPS can be operated by any individuals with no previous experience.
 Connect the UPS system only to an earthed shockproof outlet which must be easily

accessible and close to the UPS system.

 Please use only VDE-tested, CE-marked (or UL-marked for 100/110/115/120/127 VAC

models) mains cable (e.g. the mains cable of your computer) to connect the UPS
system to the building wiring outlet (shockproof outlet).

 Please use only VDE-tested, CE-marked (or UL-marked for 100/110/115/120/127 VAC

models) power cables to connect the loads to the UPS system.

 When installing the equipment, it should ensure that the sum of the leakage current

of the UPS and the connected devices does not exceed 3.5mA.

 Temperature Rating - Units are considered acceptable for use in a maximum ambient

of 40°C (104°F).

 For Pluggable Equipment - The socket-outlet shall be installed near the equipment

and shall be easily accessible.

1-4. Operation

 Do not disconnect the mains cable on the UPS system or the building wiring outlet

(shockproof socket outlet) during operations since this would cancel the protective
earthing 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 terminals block 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/Enter button to

disconnect the mains.

 Prevent no fluids or other foreign objects from inside of the UPS system.

 The UPS system operates with hazardous voltages. Repairs may be carried out only

by qualified maintenance personnel.

 Caution - risk of electric shock. Even after the unit is disconnected from the mains

(building wiring outlet), components inside the UPS system are still connected to the
battery and electrically live and dangerous.

 Before carrying out any kind of service and/or maintenance, disconnect the batteries

and verify that no current is present and no hazardous voltage exists in the terminals
of high capability capacitor such as BUS-capacitors.

 Only persons are adequately familiar with batteries and with the required

precautionary measures may replace batteries and supervise operations.
Unauthorized persons must be kept well away from the batteries.

 Caution - risk of electric shock. The battery circuit is not isolated from the input

voltage. Hazardous voltages may occur between the battery terminals and the
ground. Before touching, please verify that no voltage is present!

 Caution - Do not dispose of batteries in a fire. The batteries may explode.
 Caution - Do not open or mutilate batteries. Released electrolyte is harmful to the

skin and eyes. It may be toxic.

 Batteries may cause electric shock and have a high short-circuit current. Please take

the precautionary measures specified below and any other measures necessary when
working with batteries:

a) Remove watches, rings, or other metal objects.
b) Use tools with insulated handles.
c) Wear rubber gloves and boots.
d) Do not lay tools or metal parts on top of batteries.
e) Disconnect charging source and load prior to installing or maintaining the

battery.

f) Remove battery grounds during installation and maintenance to reduce

likelihood of shock. Remove the connection from ground if any part of the
battery is determined to be grounded.

 When changing batteries, install the same number and same type of batteries or

battery packs.

 For UPS with internally mounted battery

a) Instructions shall carry sufficient information to enable the replacement of the

battery with a suitable manufacturer and catalogue number.

b) Safety instructions to allow access by Service Personnel shall be stated in the

installation/service handbook.

c) If batteries are to be installed by Service Personnel, instructions for

interconnections, including terminal torque, shall be provided.

 Do not attempt to dispose of batteries by burning them. This could cause battery

explosion.

 Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin

and eyes. It may be toxic.

 Please replace the fuse only with the same type and amperage in order to avoid fire

hazards.

 Do not dismantle the UPS system.
 WARNING: This is a category C2 UPS product. In a residential environment, this

product may cause radio interference, in which case the user many be required to
take additional measures. (only for 220/230/240 VAC system)

Only for 110/120 VAC system:

Tower Installation

2-4. Setup the UPS

Before installing the UPS, please read below to select proper location to install UPS.

1. UPS should be placed on the flat and clean surface. Place it in an area away from vibration,

dust, humidity, high temperature, flammable liquids, gases, corrosive and conductive
contaminants. Install the UPS indoors in a clean environment, where it is away from
window and door. Maintain minimum clearance of 100mm in the bottom of the UPS to
avoid dust and high temperature.

6

2. Maintain an ambient temperature range of 0ºC to 45ºC for UPS optimal operation. For

every 5ºC above 45ºC, the UPS will derate 12% of nominal capacity at full load. The
highest working temperature requirement for UPS operation is 50ºC.

3. It’s required to maintain maximum altitude of 1000m to keep UPS normal operation at full

load UPS. If it’s used in high altitude area, please reduce connected load. Altitude derating

power with connected loads for UPS normal operation is listed as below:

4. Place UPS:

It’s equipped with fan for cooling. Therefore, place the UPS in a

well-ventilated area. It’s required to maintain minimum clearance of 100mm in the
front of the UPS and 300mm in the back and two sides of the UPS for heat dissipation and
easy-maintenance.

5. Connect to External Battery Pack

When connecting external battery packs, please be sure to connect polarity correctly. Connect
positive pole of battery pack to positive pole of external battery connector in UPS and negative
pole of battery pack to negative pole of external battery connector in UPS. Polarity

misconnection will cause UPS internal fault. It’s recommended to add one breaker between

positive pole of battery pack and positive pole of external battery connector in UPS to prevent
damage to battery packs from internal fault.

The required specification of breaker: voltage ≧ 1.25 x battery voltage/set; current ≧ 50A
Please choose battery size and connected numbers according to backup time requirement and

UPS specifications. To extend battery lifecycle, it’s recommended to use them in the
temperature range of 15ºC to 25ºC.
