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).
