2General Safety
This manual supports safe handling of the device. Use the device solely in
accordance with its intended use:
The LEAB CDR enables virtually loss-free charging of two batteries from one
source, such as an alternator or charger. The CDR is installed between the
starter and auxiliary batteries and serves as a current distributor. The LEAB
CDR is bidirectional, charging takes place in both directions.
Any modifications to the device or its components are prohibited and do not
conform to its intended use.
Observe the following safety instructions:
Danger from damaged, frozen or deformed batteries: Before charging,
make sure that the battery is undamaged and the electrolyte is not
frozen.
Only charge batteries in well-ventilated rooms and away from ignition
sources.
When handling batteries, wear acid-proof clothing.

6Mounting
To mount the device, perform the following steps:
Do not mount the device directly next to or above batteries.
To allow adequate cooling, ensure an unimpeded supply of
cooling air.
Fasten the device to the 4 lateral holes (6 mm Ø).

The device is mounted.
In vehicles with generator management, additional batteries are
not sufficiently charged by conventional cut-off relays or current
distributors.
We recommend the LEAB charge booster (part number):

Installation Instructions Optional Functions
Page 5 of 6
Connect the positive terminal of the starter battery to the screw
terminal 1 (input).
Connect the positive terminal of the additional battery to the screw
terminal 2 (output).
Connect the connection cable GND to a ground.
Connect the negative terminal of the starter battery and the negative
terminal of the additional battery to a shared ground.
Should the battery connected to the alternator or charger exceed a
voltage of 13.5 V or 27 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.
The LED integrated in the CDR lights up when current (> 1 A) is
connected through.
Optional: To connect an external LED, connect the blue connecting cable
to an LED.
Optional: To connect a bypass button, connect the blue connecting
cable to a button.
The CDR is installed.
8Optional Functions
Bypass Function
The bypass function is used to charge the starter battery with the additional
battery if the voltage of the starter battery is too low.
To use this function, connect a button with the connection cable for the
bypass button.
LED Remote Display
An external LED can be connected and used as a remote display to detect
whether the CDR is conducting current.
To use this function, connect an LED (output 5 V, max. 5 mA) to the
connecting cable for the LED.
