Maintenance & Testing

6.0 Maintenance & Testing

UPS maintenance should be carried out by trained service engineers only. Service and maintenance contract is recommended.

6.1Fan

It is recommended to replace fans every 3 years.

6.2Battery Monitoring Test

Systems with built-in batteries have a standard battery monitoring feature (optional in other systems).

Battery Test Results:

1.Battery OK. Back-up time normal.

2.Reduced battery capacity - “Battery weak” .

3.Battery capacity too low - “Battery defective”

Carry out battery monitoring test by discharging max. 25% of battery energy. For systems with no battery monitor/no excess back-up time, a battery capacity test is recommended every 6 months.

Carry out battery tests when load is least affected.

Allow 16 hours to restore full back-up time after battery capacity tests
