10 Service
The Protect B. PRO is comprised of state-of-the-art, low-wearing
parts. We recommend, however, that you carry out visual checks
(especially of the battery and fan) at regular intervals (at least
every 6 months, however) to maintain continual availability and
operating reliability.
CAUTION!
Working area protection and the safety regula-
tions must be complied with!
10.1 Charging the battery
The battery is automatically charged via the mains connection,
regardless of the operating mode (standby, ECO, AVR).
The full charging time of the battery after a longer discharging
period should be at least 8 hours, in conjunction with an external
additional battery unit at least 24 hours.
