Use the device solely in accordance with its intended use. Observe the safety instructions. WARNING Risk of injury from damaged, frozen or deformed batteries Damaged, frozen or deformed batteries can cause injuries. 1. Before using the battery, make sure that the battery is undamaged and the electrolyte is not frozen. WARNING Risk of fire from overheated battery Flammable gases can escape if the battery overheats. 1. Always charge batteries in well-ventilated rooms and away from ignition sources. 4 LEAB Automotive GmbH Thorshammer 6 24866 Busdorf LEAB Automotive GmbH 2 General Safety WARNING Burns from escaping acid Acid can leak out when handling batteries. 1. Wear acid-proof clothing when handling batteries. WARNING Danger from short circuits Contact of the screw terminals with metallic and/or conductive vehicle parts can cause short circuits that can lead to serious injuries. 1. Avoid contact of the screw terminals with metallic and/or conductive vehicle parts. 2.1 Intended Use The CDR 12/24 V can be installed between the starter and auxiliary battery as an electronic charging current distributor. The charging current can be distributed both bi-directionally and unidirectionally. The batteries 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. 2.2 Foreseeable Misuse Use the insulating caps supplied. Protect supply lines with a suitable fuse. Only use appropriate electrical cables with a suitable cross-section. Only use suitable ring cable lugs and tools intended for this purpose. Install the CDR in such a way that cooling is made possible by air supply.

Maximum torque: 10 Nm To assemble the device, perform the following steps: ü Choose a cool, dry and well-ventilated assembly site. ü Do not mount the device directly next to or above batteries. ü Guarantee adequate cooling for an unimpeded supply of cooling air. 1 Fasten the device to the 4 holes on the side (Ø 6 mm). ð The device is assembled. 8 LEAB Automotive GmbH Thorshammer 6 24866 Busdorf LEAB Automotive GmbH 7 Installation 7 Installation TIP In vehicles with generator management, auxiliary batteries are not sufficiently charged by conventional cut-off relays or current distributors. LEAB recommends installing the charge booster BPC 12-12/40 (part no.: 1041003001). To install the device, perform the following steps: NOTE! Maximum screw terminal torque: 20 Nm 1 Connect the positive terminal of the starter battery to screw terminal 1 (in- put). 2 Connect the positive terminal of the auxiliary battery to screw terminal 2 (output). 3 Connect the plug contact PIN 5 (connection for GND) to a ground. 4 Connect the negative terminal of the starter battery and the negative terminal of the auxiliary battery to a common ground. ð The device is installed. TIP Various optional functions can be installed via the plug contacts PIN 1-5. Use 6.3 mm flat plugs. LEAB Automotive GmbH Thorshammer 6 24866 Busdorf 9 7 Installation LEAB Automotive GmbH 7.1 Optional: Activate bypass function The bypass function (permanently ON) is used to charge the starter battery with the auxiliary battery if the voltage of the starter battery is too low. The voltage detection through PIN 5 (GND) is deactivated so that the CDR distributes charging current at any voltage. To use the function, carry out the following step: 1 Switch the plug contact PIN 4 to ground. ð The function is activated. 7.2 Optional: Connect remote LED display An external LED can be connected and used as a remote display to detect whether the device is conducting current. To install the function, perform the following step: NOTE! External LED: Output 5 V, max. 5 mA. Not included in the scope of delivery. 1 Connect the plug contact PIN 1 to the input of an external LED. 2 Connect the other terminal of the external LED to ground. ð The function is installed. 7.3 Optional: Change the charging current distribution The CDR can distribute the charging current both bidirectionally and unidirectionally. The factory default setting is bidirectional charging current distribution in two directions. To change the direction of the charging current distribution to unidirectional, carry out the following step: 1 Switch the plug contact PIN 2 to ground. ð The charging current distribution is unidirectional from screw terminal 1 to screw terminal 2. 10 LEAB Automotive GmbH Thorshammer 6 24866 Busdorf LEAB Automotive GmbH 7 Installation To change the direction of the charging current distribution to bidirectional, carry out the following step: 2 Disconnect the connection cable from plug contact PIN 2. ð The charging current distribution is bidirectional from screw terminal 1 to screw terminal 2 or vice versa, depending on where a higher voltage is present. 7.4 Optional: Activate switch-off function The CDR can be switched off manually (permanently OFF) to prevent overcharging of a fully charged lithium-ion battery. The device can therefore be used as an automatic cut-off relay to connect/disconnect a consumer or an onboard supply system. NOTE! The disconnection is independent of the direction of the charging current selected. To activate the function, perform the following step: 1 Switch the plug contact PIN 3 to ground. ð The function is activated. The device is switched off. LEAB Automotive GmbH Thorshammer 6 24866 Busdorf 11 8 Operation LEAB Automotive GmbH 8 Operation Should the battery connected to the alternator or charger exceed a voltage of 13.5 V or 27.5 V, the CDR will switch on the auxiliary battery for charging. Should the voltage drop below 12.8 V or 25.6 V, the CDR will disconnect the batteries to prevent mutual discharge.
