Improper Use; Battery Care; Device Elements - Truma SDC 10 Operating Instructions & Installation Instructions

Improper use

The device is not suitable for charging
– 6 V batteries or 6 V lead accumulators
– non-chargeable batteries
– nickel-cadmium batteries.
If batteries with a rated voltage of 6 V are charged with the
device, gassing occurs immediately. An explosive gas can be
created.
The device is only suitable for regulating solar modules. Do
not connect any other voltage sources (e.g. main voltage
230 V) to the device. This may destroy the device and/or
sources. If any other voltage sources are used together with
the device, please ask your dealer.

Battery care

(also maintenance-free batteries)
The following points should be observed to extend the
battery life:
– Batteries should be fully charged before and after being
used.
– In the case of longer standstills (without sunshine), discon-
nect the battery and charge for 24 hours at the latest every
12 weeks.
Store fully charged batteries in a cool but frost-free place
during the winter and recharge regularly (every 12 weeks).
