Digital Energy™ LP Series

8 - Maintenance

8.1General

When used properly, the UPS is virtually maintenance free other than keeping the air inlets/outlets free from dust.

8.2Cooling fan

The expected operational life of the cooling fans is approximately 20,000 to 40,000 hours of continuous operation. A high ambient temperature will shorten this operational life.

8.3Batteries

The service life of the battery is from 3 to 6 years, depending on the operating temperature and on the number of discharge cycles.

As a healthy battery is essential to the performance of the UPS, an automatic battery test is performed regularly to ensure failsafe operation (see section 5.4.1). When the condition of the battery is critical, the warning signal will be activated (buzzer 1x per 8 secs, and alarm message 'Replace battery', see 5.3.2). The batteries must be replaced as soon as possible. Please contact your dealer. Use only UL recognised batteries (BAZR2), valve

regulated types.

NOTE: under certain circumstances a manual battery test can result in a false alarm: please see section 5.4.2

'QUICK BATTERY TEST'.

Regular deep battery tests are advised in order to re-calibrate the capacity of aging batteries. See section 5.4.3 for more information.

NOTE: All maintenance and service work, including battery replacement, should be performed by qualified service personnel.

For authorized service personnel only:

Never short the battery terminals. Shorting may cause the battery to burn. Avoid charging in a sealed container. Proper disposal of batteries is required: refer to your local codes for disposal requirements. Never dispose of batteries in a fire: they may explode. Never disassemble or reassemble batteries; their contents (electrolyte) may be extremely toxic. If exposed to electrolyte, wash immediately with plenty of water, if eye contact occurs flush with water and contact a physician.

8.4Safety

CAUTION:

When the LP-U UPS is operating, all parts of the electronics are directly connected to the utility and high voltages are present on all internal parts, including the battery. Even after disconnection from the utility, all parts inside the UPS, including the battery, conduct dangerous voltages (except the RS232 output).

For your safety, only authorized service personnel may remove the cabinet cover.

8.5Storage

Always store the UPS in a dry location with the batteries in a fully charged state, storage temperature must be within -20 and +45° C. Storing the unit for a period exceeding 3 months can reduce the life of the batteries. To maintain their normal life expectancy, the batteries must be recharged periodically:

-if the storage temperature is within -20 and +30°C (-4°F and 86° F): every 6 months, for 24 hours,

-if the storage temperature is within -20 and +45°C (-4°F and 113° F): every 4 months, for 24 hours.

8.6Recycling the UPS at the end of service life

NOTE: This product has been designed to respect the environment, using materials and components respecting eco-design rules. It does not contain CFCs (Carbon Fluorine Chloride) of HCFCs (Halogen Carbon Fluorine Chloride).

GE Digital Energy, in compliance with environment protection recommends that the UPS equipment, at the end of its service life, must be recycled conforming to the local applicable regulations.

WARNING

The batteries contain lead, which is a dangerous substance for the environment. Therefore the batteries must be recycled correctly by specialized companies.
