1. Important Safety Warning
SAVE THESE INSTRUCTIONS - This manual contains important instructions that should be followed
during installation and maintenance of the UPS and batteries. Please comply with all warnings and
operating instructions in this manual strictly. Do not operate this unit before reading through all safety
information and operating instructions carefully.
1.1 Transportation and Storage
• 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 environments.
The UPS system must be absolutely dry before being installed. Please allow at least two hours
for the UPS system to acclimate to 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 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 cables approved by regulatory agencies (e.g. the mains cable of your computer)
to connect the UPS system to the building wiring outlet (shockproof outlet).
• Please use cables approved by regulatory agencies 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.
• CAUTION: The unit is heavy. Lifting the unit requires a minimum of two people.
• Batteries with minimum case ame rating V-2 are intended for use in a computer room as dened
in the Standard for the Protection of Information Technology Equipment, ANSI/NFAP 75.
Batteries with case ame rating HB are not intended for use in a computer room.
(US installations only.)
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, rst press the OFF/Enter button to turn off the unit.

VD-Series (1000VA-3000VA)Chatsworth Products (CPI)
• Prevent uids or other foreign objects from inside of the UPS system.
• The EPO and USB circuits are an IEC 60950-1 safety extra low voltage (SELV) circuit. This
circuit must be separated from any hazardous voltage circuits by reinforced insulation.
1.5 Maintenance, service and faults
• The UPS system operates with hazardous voltages. Repairs may be carried out only by qualied
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 capabili
capacitor such as BUS-capacitors.
• To avoid electrical shock, turn off the unit and unplug it form the AC power source before
servicing the battery
• Only persons adequately familiar with batteries and with the required precautionary measures
may replace batteries and supervise operations. Unauthorized persons must be kept well awa
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 re. The batteries may explode.
• Caution - Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes.
It may be toxic.
• A battery can may cause a risk of electrical shock and high short-circuit current
The following precautions should be observed when working on 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 prior to connecting or disconnecting battery terminals.
f) 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
• When changing batteries, install the same number and same type of batteries or battery packs.
• Please replace the fuse only with the same type and amperage in order to avoid re hazards.
• Do not dismantle the UPS system.

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, gas, corrosive and conductive contaminants.
Install the UPS indoors in a clean environment, where it is away from window and door. Maintain
minimum clearance of 4” (100mm) in the bottom of the UPS to avoid dust and high temperature.
2.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 4” (100mm) in the front of the UPS and 12” (300mm) in the back
and two sides of the UPS for heat dissipation and easy-maintenance.
Step 1: External battery connection
For safety consideration, the UPS is shipped out from factory without connecting battery wires. Before
connecting to external batteries, it’s required to have the internal battery wire disconnected. Follow the
below steps to make external battery connection.
1. Turn off UPS and remove power plug from the mains.
2. Remove front panel and disconnect internal battery wire.
