IMPORTANT SAFETY WARNING

Please read the following instructions carefully before installing the unit and strictly comply with all the warnings and operating instructions herein. Save this manual for future reference and do not operate this unit before reading through all safety information and operating instructions carefully.

Transportation

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

Preparation

• Condensation may occur if the UPS system is moved directly from a 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 acclimatize 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 near a 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.
• Do not place cables in such a way that 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 individual with no previous experience.
• Connect the UPS system to an earthed shock-proof outlet which must be easily accessible and close to the UPS system.
• Use only VDE-tested, CE-marked, ISI-marked mains cable (e.g. the mains cable of your computer) to connect the UPS system to the building wiring outlet (shock-proof outlet).
• Use only VDE-tested, CE-marked, ISI-marked 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 3.5 mA.
• UPS is designed for linear load, worst case inductive resistive load.

Operation

• Do not disconnect the mains cable on the UPS system or the building wiring outlet (shock-proof socket outlet) during operations since this would cancel the protective earthing of the UPS system and 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 fluids or other foreign objects from entering the UPS system.

Maintenance, service and faults

• 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.
  They might be 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 exist in the terminals of high-capability capacitor such as BUS capacitors.

• Only people adequately familiar with batteries and with the required precautionary measures may replace batteries and supervise operations. Unauthorized persons must be kept 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 specified below and any other measures necessary when working with batteries:

• Remove wristwatches, rings and other metal object

• 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 the batteries to explode.

• Do not open or destroy batteries. Escaping electrolytes can be toxic and cause injury to the skin and eyes.

• Replace the fuse with the same type and amperage in order to avoid fire hazards.

• Do not dismantle the UPS system.

• Connect UPS to short-circuit-protected building wiring.

• The UPS system has internal fuses on both DC & AC inputs. Those devices do not protect the upstream cables connected to DC & AC inputs and upstream breakers or fuses shall be set up in accordance with AC & DC wires ratings to meet the local national electrical code standard.

INSTALLATION AND SETUP

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

2. Input circuit breaker
3. USB communication port
4. RS-232 communication port
5. SNMP intelligent slot (optional)
6. External battery connection
7. Output receptacles
8. Output terminal

Setting up the UPS

Step 1: UPS input connection
Plug the UPS into a 2-pole, 3-wire, grounded receptacle only. Please use recommended cable and breaker for input.

Mode| Wire size in sq. mm./No. of runs| Recommended input breaker
---|---|---
1 kVA – FM/FMI| 2.5/3| 16 A AC (C Curve)
2 kVA – FM/FMI| 6.0/3| 32 A AC (C Curve)
3 kVA – FM/FMI| 10.0/3| 40 A AC (C Curve)

Step 2: UPS output connection

• For socket-type outputs, simply connect the devices to the outlets.
• For terminal-type input or outputs, please follow the steps below, for the wiring configuration:
  • Remove the small cover of the terminal block.
  • Use AWG14 or 2.1 mm2 power cords.
  • Upon completion of the wiring configuration, please check whether the wires are securely affixed.
  • Put the small cover back to the rear panel.

Communication port:

Step 3: Communication connection
To allow for unattended UPS shutdown/start-up and status monitoring, connect one end of then communication cable 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 a PC.
The UPS is equipped with intelligent slot for either SNMP or AS400 card. Installing either SNMP or AS400 card in the UPS, will provide advanced communication and monitoring options.

Note: USB port and RS-232 port can’t work at the same time.

Step 4: Turn on the UPS
Press the ON/Mute button on the front panel for two seconds to power on the UPS.

Note: The battery charges fully during the first five hours of normal operation. Do not expect full battery run capability during this initial charge period.

Step 5: Install software
You may insert the CD provided into the CD-ROM to install the monitoring software.
If not, please follow the on screen instructions to install the software. When your computer restarts, the monitoring software will appear as an orange plug icon located in the system tray near the clock.

Step 6: External battery connection
This UPS series is not including batteries. Batteries are connected in a separate cabinet with protection.
Please connect external batteries as below chart.

STORAGE AND MAINTENANCE

Operation
The UPS system contains no user-serviceable parts. If the battery service life (3~5 years at 25°C ambient temperature) has been exceeded, the batteries must be replaced. In this case,please contact your dealer.
Be sure to deliver the used battery to a recycling facility or ship it to your dealer in the replacement battery packing material.

Storage
Before storing, charge the UPS for 5 hours. Store the UPS covered and upright in a cool, dry location.
During storage, recharge the battery in accordance with the following table:

Disposal
Ref. standard: ISO 14001:2015

• After unpacking the UPS and Battery, the removed packaging materials like polythene paper, thermocole/polyethylene, carton box, Nylon belt, nylon thread shall be collected and disposed through authorized recycler.
• Batteries when found faulty/damaged must be handed over to identified authorized recycler or to NUMERIC, where it is disposed properly.
• Battery contains harmful metals and chemicals such as nickel-cadmium, alkaline, mercury, nickel-metal hydride and lead acid, which contaminates if it is not disposed properly.
• When batteries containing cadmium is used in fills, they will eventually dissolve and release the toxic substance than can seep into water supplies posing serious health hazards for the population/society. Hence, recycling of batteries will prevent pollution and also saves resource.
