12. MAINTENANCE
WARNING!
The UPS generates HAZARDOUS INTERNAL VOLTAGES. All maintenance operations should be carried out by
AUTHORISED SERVICE ENGINEERS ONLY.
• The unit will operate to its maximum capability if kept powered round the clock (24/7); this ensures that the batteries will
always be properly charged.
• If the appliance is not to be used for any length of time wait until the batteries are fully charged (connection to mains
power supply for 8 hours continuous) before shutting the UPS down.
• Recharge the batteries for a duration of 24 hours at least every 4 weeks when the unit is not in use.
12.1. Storage
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 spent battery to a recycling facility or ship it to your dealer in the replacement
battery packing material.
Before storing, charge the UPS 5 hours. Store the UPS covered and upright in a cool, dry location. During storage,
recharge the battery in accordance with the following table:
Storage temperature Recharge frequency Charging duration
-25°C to 40°C Every 3 months 1-2 hours
40°C to 45°C Every 2 months 1-2 hours
