9.2 Illuminated switch function
• The illumination of the illuminated switch indicates that the electrical consumers con-
nected to the sonnenProtect are causing excessive power consumption.
• Backup operation is stopped when an overload is detected until there is no more over-
load and the illuminated switch has been pressed for approx. 2 seconds.
When the illuminated switch lights up:
„
Switch off electrical consumers in the backup circuit or do not connect any electrical
consumers to the backup circuit if their power consumption exceeds the nominal
power or (when switching on) the maximum power of the sonnenProtect.
„
Press the illuminated switch for approx. 2 seconds.
ð
Backup operation has started successfully when the illuminated switch no longer lights
up.
„
Further information for specific situations can be found in section Troubleshooting
[P. 84].
9.3 Type plate
The type plate is located on the outer surface of the sonnenProtect. The type plate can be
used to uniquely identify the sonnenProtect. The information on the type plate is required
for the safe use of the system and for service matters.
The following information is specified on the type plate:
• Item designation
• Item number
• Technical data of the storage system
A duplicate of the type label for the sonnenProtect 4000 must be affixed by the installer
to the storage system (see Attaching type label to storage system [P. 73]).
