8.1 UPS

UPS Cleaning

Regularly clean the UPS, especially the slits and openings, to ensure that the

air freely flows into the UPS to avoid overheating. If necessary, use an air-gun

to clean the slits and openings to prevent any object from blocking or covering

these areas.

UPS Regular Inspection

Regularly check the UPS every half year and inspect:

1. Whether the UPS, LEDs, and alarm function are operating normally.

2. Whether battery voltage is normal. If battery voltage is too high or too low,

find the root cause.

8.2 Batteries

The M series UPS uses sealed lead-acid batteries. Though the typical battery life

cycle is 3 years, the battery life depends on the temperature, the usage, and the

charging/ discharging frequency. High temperature environments and high charging/

discharging frequency will quickly shorten the battery life. The UPS does not require

maintenance by the user; however, the batteries should be checked periodically.

Please follow the suggestions below to ensure a normal battery lifetime.

Keep usage temperature at 25°C.

When the UPS needs to be stored for an extended period of time, the batteries

must be recharged once every three months and the charging time must not be

less than 6 hours each time. If a Delta external battery pack is connected, the

charging time should not be less than 12 hours.

NOTE:

tact qualified service personnel. During battery replacement, the loads

attached to the UPS will not be protected if input power fails.
