Connections
For correct connection - see drawings "INSTALLATION".
• Use reliable cord end terminals to fix the wires to the
DC-input and –output.
• See specifications for the recommended wire size.
• To minimize any EMC-interference we advise to
connect the negative pole of the supplying battery to
the ground.
Connect a momentary switch between the "switch"-
connection and the DC-output ground if you want to use
the remote switch function and/or the light dimmer
function (see drawing 1B, 2B, 3B).
Alarm contact
The alarm contact, right side connection on the back
(see drawings "DIMENSIONS"), is connected to the
contact. The contact is activated and connected to the
output ground in a normal situation, and will be
deactivated if the input voltage is too low (default 10.0V
or 20.0V), if the input voltage is too high (default 16.0V
or 32.0V), in case of overload or short-circuit. The
contact is also deactivated when the MAGIC is switched
off.
Operation
The converter operates automatically. Under normal
circumstances, there is no need for operation. Despite
its low no-load consumption, the converter should be
disconnected from the supplying battery when it is not in
use to protect the battery from discharging.
Refer to table "SWITCH OPERATION" for explanation of
the remote switch function / dimmer operation.
