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!

10.1Charging 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).
