This accumulator saver protects your car battery from total discharge by switching off consumers such as ice boxes, heaters, etc

This accumulator saver protects your car battery from total discharge by switching off
consumers such as ice boxes, heaters, radios + television sets, etc. in time. It switches
on again automatically after return of the normal voltage. The interrupting voltage is
adjustable: approx. 10.413.3 V, max. 20 A.



The module is installed in such a manner that it is not exposed to humidity, strong vibrations or great heat. The connections are linked
with the battery and consumer according to the drawing. Please use cables with a sufficient cross section (if possible > 1.5 mm²), so that a too
high loss of voltage in the cable is avoided.
It is absolutely necessary to superpose a safety fuse according to the drawing!
Attention: Short-circuits or overload on the consumer side of the module may cause that the module will be damaged and then does not switch
off any longer! Due to the fact that the function of each module has been tested thoroughly before dispatch, replacement at our expense is not
possible in such cases or in case of damage due to too high voltage (> 15 V)!
The metal base plate of the module may heat up depending on the load. No additional cooling is required for load currents up to approx. 10 A.
The module should, however, be installed well ventilated so that any heat that may possibly occur is carried off from the metal plate through
circulation of air. In case of higher currents 10...20 A the module has to be mounted with a metal plate planely on another larger metal plate so
that the heat will be carried off. We recommend a plate of approx. 10 x 15 x 0.5 cm or the like with a similar cooling effect. The base plate of the
module must not heat up to more than 70° C during continuous operation.
The interrupting voltage may be adjusted with the small adjustable capacitor next to the plug-in connections. If the controller is turned completely
to the left stop, the module disconnects at approx. 10.4 V (± 0.3 V) and at the right stop at approx. 13.3 V (± 0.3 V). Voltages lying in between can
be adjusted continuously. We recommend to set the controller to a middle position. The module then disconnects at approx. 11.7 V (± 0.3 V) and
this is optimal for the lifetime of the accumulator. When choosing a lower adjustment the capacity of the accumulator is indeed utilized to a
higher extent but the lifetime reduces considerably. Note: a full new 12 V-accumulator has a voltage of approx. 13.514 V.
Important: The module always connects with a time delay at first so that it does not disconnect and connect again due to short-term voltage fluctuations
because of short-term current increases. At this adjustment please always wait a couple of minutes until the module reacts.
Check list for troubleshooting: The usage of cables which are too thin or too long may cause a loss of voltage in the cable and thus the module
switches off continuously!
Intended use: Protection of a car battery against total discharge through connected consumers in summer houses, camping tents, parking caravans
etc.
Important information: The connections of the connected load must not be connected with earth (chassis). Reason: The module switches the
negative pole on or off. If these connections are connected with earth in each case, the module would be bypassed through the earth connection
and would be ineffective.
