UPS MAINTENANCE
UPS CARE
For the best preventive maintenance:
Keep the area around the equipment clean
Keep the equipment free from dust
Ensure the equipment is positioned in a well-ventilated area
For maximum battery life keep the equipment at an ambient temperature of 20-25°C (77°F max)
Carry out regular environmental and battery checks
The batteries are rated for a 3–5-year service life. The service life varies depending on the frequency of usage
and ambient temperature. Batteries used beyond expected service life will often have severely reduced
runtimes. Replace batteries at least every 4 years to keep units running at peak efficiency and prevent failure.
7.1
TRANSPORTING THE UPS
The following procedure should be performed or supervised by personnel knowledgeable about batteries
and the required precautions. Keep unauthorised personnel away from batteries. If the UPS requires any type
of transportation, the batteries must be disconnected (but not removed) before the unit is transported:
Verify that the UPS is off and disconnected from mains power
Place the UPS on a flat stable surface with the front of the cabinet facing you
Remove the UPS front cover
Disconnect the internal battery connectors
Replace the UPS front cover
To avoid damage and to prevent DOA’s always use a reputable courier for all equipment transportation.
7.2
STORING THE UPS
Where UPS equipment is stored for a long period, the batteries must be recharged every six months. The optimal
storage VDC for VLRA batteries, depending on the environment is between 20-40%. This can be achieved by
connecting the UPS to mains power.
DO NOT
Store the equipment in a warm, damp, dusty environment
DO NOT
Use the equipment if the batteries have not been recharged/if the recharge date exceeds six months
DO NOT
Expose the UPS to direct sunlight or source of heat
DO
Store the equipment in a cool, dry, clean environment
DO
Ensure the batteries are recharged every six months for a minimum of 48 hours
DO
Ensure EBMs are recharged every six months for a minimum of 3 hours
ADOPTING A PREVENTATIVE MAINTENANCE SCHEDULE IS CRITICAL TO ACHIEVING OPTIMUM UPS PERFORMANCE
THE INTERNAL UPS BATTERIES MUST BE DISCONNECTED BEFORE TRANSPORT
UPS BATTERIES MUST BE RECHARGED EVERY SIX MONTHS. ALWAYS CHECK THE BATTERY RECHARGE DATE ON THE
SHIPPING CARTON BEFORE USE.
