1.1 Save these instructions

This manual contains important instructions for the UPS that should be followed during installation and maintenance of the UPS and the batteries.

Before attempting to install and start up the UPS, carefully read this manual. Keep this manual next to the UPS for future references. All servicing must be done by qualified personnel. Do not attempt to service the UPS unless you have had proper training.

WARNING: By opening or removing covers you run the risk of

exposure to dangerous voltages!

While every care has been taken to ensure the completeness and accuracy of this manual, GE accepts no responsibility or liability for any loss or damage resulting from the use of the information contained in this document. This document shall not be copied nor reproduced without the permission of GE. Due to technical improvements, some of the information contained in this manual may be changed without notice.

1.2 General

1.3 Installation

• CAUTION: RISK OF ELECTRIC SHOCK.

• The UPS has an internal battery supply, with a nominal voltage of (UPS rating /

voltage): 1kVA / 36Vdc, 1.5kVA / 48Vdc, 3kVA / 72Vdc.

• The appliance outlets may be electrically live, even when the UPS is disconnected from the utility supply. Dangerous voltages may be present during battery operation.

• The batteries must be disconnected during maintenance or service work.

• The UPS contains potentially hazardous voltages.

• The unit should be installed by service personnel.

• To reduce the risk of electric shock, install this UPS in a temperature and humidity

controlled indoor area free of conductive contaminants.

• Ambient temperature must not exceed 40°C (104°F). Optimal battery lifetime is obtained if the ambient temperature does not exceed 30°C (86°F).

• It is important that the unit has adequate ventilation. Maintain air movement around and through the unit. Do not block the air vents.

• Avoid placing the unit in direct sunlight or near heat sources.

• The UPS should only be powered from a 2-pole 3-wire grounded wall outlet. This

outlet must be easily accessible and located near the UPS.

• Do not use extension cords when connecting the UPS to the utility power supply.

• The AC output of the UPS needs a disconnecting switch such as a breaker, which

has to be provided by others.

The over current protection for the output AC circuit has to be provided by others. All

•

of our UPS have an electronic protection of AC output short circuit.

• Avoid spilling liquids on or dropping any foreign object into the UPS.

• Do not plug a laser printer or household appliances such as electric heaters or

vacuum cleaners into the UPS. The UPS output is intended to be used only for electronic loads such as computers and telecommunications equipment.

• Upon installation, it should be ensured that the sum of the leakage currents of the UPS and the connected loads does not exceed 3.5mA.

• Properly trained personnel should operate the unit.

- 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 the battery is inadvertently grounded. If inadvertently grounded,

1.6 FCCIS Interference Statements

1kVA MODEL

Federal Communications Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures:

• Reorient or relocate the receiving antenna

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the

receiver is connected.

• Consult the dealer or an experienced radio/TV technician for help.

FCC Caution: To assure continued compliance, use only shielded interface cables

when connecting to computer or peripheral devices. Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

1.5 and 3kVA MODELS Federal Communications Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at their own expense.

FCC Caution: To assure continued compliance use only shielded interface cables
