7 Maintenance

The PROTECT B. consists of advanced and resistant components. To guarantee a continuous and high availability it is recommended to check the unit (especially the batteries and the fans) in regular intervals (at least every 6 months).

CAUTION:

Follow safety and security regulations unconditionally!

Visual control

When going through the visual control check whether:

♦mechanical defects or foreign matter is visible in the system

♦conducting dirt or dust sediments are in the unit and

♦dust sediments prevent optimal ventilation in and out the unit.

CAUTION:

Before going through the next step disconnect the PROTECT B. from the mains.

If the unit is very dusty it is recommended to clean the UPS with compressed air to enable optimal ventilation.

The time intervals for the visual control depend mainly on the local situation at the deployment site.

Battery control

The aging process can be detected by regular capacity probes. Make comparison measurements every 12 month e.g. by simulating a power failure and check how long the standby time lasts. The load should always be the same for each simulation. Dramatic changes compared to the last measurements require a change of batteries. Contact your local dealer or call our hotline (see page 4).
