11 MAINTENANCE
All maintenance and service works must be performed by QUALIFIED SERVICE
PERSON.
11.1 GENERAL MAINTENANCE
When used properly, the LP 33 UPS is virtually maintenance free.
Take care of proper environmental conditions (see Section 4.5 – Ventilation & Cooling) and keep
air inlets/outlets free from dust and any other obstacle.
11.2 COOLING FAN MAINTENANCE
The expected operational life of the cooling fans is approximately 40.000 hours of continuous
operation.
A high ambient temperature will shorten this operational life.
11.3 BATTERY MAINTENANCE
The service life of the battery is from 3 to 6 years, depending on the operating temperature and on
the number of discharge cycles.
The UPS LP 33 offers the possibility of SBM (Superior Battery Management).
The function SBM can be activated through a service Parameter.
The functionality of SBM reduces the Battery recharging time together with improved lifetime of the
Battery.
As a healthy battery is essential to the performance of the UPS, an automatic or manual battery
test can be performed regularly to ensure failsafe operation, in order to check if the battery can
provide the expected backup time in case of mains failure.
We recommend the battery test be performed at least every 1 month, especially if the battery is
not sufficiently discharged during normal operation.
Since the parameter enabling the battery test protected by user password, please contact your
Service Centre for more information.
Please consider that, if you did a full battery test to verify the full runtime of the battery, the charger
needs at least 8 hours to recharge the battery up to 90% of its capacity.
To guarantee that the battery is fully charged, the UPS system should be in operation for at least
12 hours every 3 months.
When the condition of the battery is critical, the warning signal will be activated (general alarm,
buzzer and alarm message “4118 - Battery fault”).
In this case the battery must be replaced as soon as possible.
Please contact your Centre Service.
