General Safety
This manual will help you to handle the device safely. Use the device
solely in accordance with its intended use:
The CDR 12/24 V can be installed between the starter and auxiliary bat-
tery as an electronic charging current distributor. The charging current
can be distributed both bi-directionally and unidirectionally. The batter-
ies are charged almost loss-free and the plastic housing protects against
short circuits.
Thanks to a switch-off function, it can also be used as an automatic cut-
off relay to switch a consumer or an on-board supply system on or off.
The device is designed for an operating temperature of -40 °C ... +60 °C.
Observe the safety instructions.
WARNING!
Risk of injury from damaged, frozen or deformed bat-
teries. Before using the battery, make sure that the battery is undamaged
and the electrolyte is not frozen.
WARNING!
Risk of fire from overheated battery. Only charge bat-
teries in well-ventilated rooms and away from ignition sources.
WARNING!
Danger of burns from escaping acid. Wear acid-proof
clothing when handling batteries.
WARNING!
Danger from short circuits. Avoid contact of the screw
terminals with metallic and/or conductive vehicle parts.
