10 Maintenance
The PROTECT 1. consists of state-of-the-art, non-wearing
components. We do, however, recommend visual checks
(above all battery and fan checks) at regular intervals (at least
every 6 months) to maintain continuous availability and
operational reliability.
CAUTION!
Ensure that the work area is cordoned off and
always observe the safety instructions!
10.1 Charging the Battery
The battery is automatically charged when the mains is
connected, irrespective of the operating mode. This is signalled
by the Load LED’s lighting up (see also chapter 4.4.2).
The complete charging time of the battery after a long
discharge time depends especially on the number of additional
external battery units (see chapter 2.3).
10.2 Checks
The following maintenance work should be performed:
