Important Safety Warning
Please comply with all warnings and operating instructions in this manual strictly. Save this manual prop-
erly 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.
Transportation
• Please transport the UPS system only in the original package to protect against shock and impact.
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.
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 power 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 power 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.
• Check if there is a protection device against over current and short circuit in the upstream of the
UPS system. The recommended protection spec is 11A for 800VA, 1100VA, 15A for 1500VA,
20A for 2000VA, 2200VA and 30A for 3000VA with a B or C trip curve.
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.

CPI User Manual for Lead Acid Line Interactive UPS 04/22v.1 Page 5
VL-Series (800VA-5000VA)Chatsworth Products (CPI)
• In order to fully disconnect the UPS system, rst press the OFF/Enter button to disconnect
• the mains.
• Prevent no uids or other foreign objects from inside of the UPS system.
• The EPO, RS-232 and USB circuits are an IEC 60950 safety extra low voltage (SELV) circuit. This
circuit must be separated from any hazardous voltage circuits by reinforced insulation.
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 capability
• 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 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!
• Batteries may cause electric shock and have a high short-circuit current. Please take the
• precautionary measures specied below and any other measures necessary when working
• with batteries:
»Remove wristwatches, rings and other metal objects
»Use only tools with insulated grips and handles.
• When changing batteries, install the same number and same type of batteries.
• 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.
• When replacing batteries, replace with the same type and number of batteries or battery packs.
• Do not dismantle the UPS system.
• A battery can present a risk of electrical shock and high short-circuit current. The following
• precautions should be observed when working on batteries:
»Remove watches, rings, or other metal objects.
»Use tools with insulated handles.
»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.

Setup the UPS
UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension cords.
UPS output connection
There are two kinds of outputs: programmable outlets and general outlets. Please connect non-critical
devices to the programmable outlets and critical devices to the general outlets. During power failure, you
may extend the backup time to critical devices by setting shorter backup time for non-critical devices.
Communication connection
Communication ports:
USB port RS-232 port Intelligent slot
To allow for unattended UPS shutdown/start-up and status monitoring, connect the communication
cable one end to the USB/RS-232 port and the other to the communication port of your PC. With
the monitoring software installed, you can schedule UPS shutdown/start-up and monitor UPS status
through PC.
The UPS is equipped with intelligent slot perfect for either SNMP or Dry Contact/Relay card. When in-
stalling either SNMP or Dry Contact/Relay card in the UPS, it will provide advanced communication and
monitoring options.
USB port and RS-232 port can’t work at the same time.
Surge Protection
Fax/Phone surge port
Connect a single modem/phone/fax line into surge-protected “IN” outlet on the back panel of the UPS
unit. Connect from “OUT” outlet to the equipment with another modem/fax/phone line cable.
