10 Maintenance
The PROTECT D. is constructed using modern, low-wear
components. Nevertheless, in order to maintain constant
availability and operating reliability, it is advisable to make visual
checks (of the battery and the vents in particular) at regular
intervals (but at least every 6 months).
CAUTION!
Always make sure to secure the working area and
carefully follow all safety instructions!
10.1 Charging the battery
The battery is always charged automatically when connected to
the mains power supply, regardless of the operating mode.
IMPORTANT: The battery charging module must be activated
(presetting, also see Chapter 7.3.6 on pg. 49ff).
The total charging time for the battery after it has been
discharged for a long period of time can depend on the number
of additional external battery units (see Chapter 2.3).
