deeply discharged by the loads. The charging takes place through multiple stages which include
automatic adaptation to the ambient temperature for optimal charging of the battery.
z The controller is intended for use at 12 V system voltages.
z The charge controller has a number of safety and display functions.
Mounting and Connecting
The controller is intended for indoor use only. Protect it from direct sunlight and place it in a dry
environment. Never install it in humid rooms (like bathrooms).
The controller measures the ambient temperature to determine the charging voltage. Controller and battery
must be installed in the same room.
The controller warms up during operation, and should therefore be installed on a non flammable surface only.
REMARK: Connect the controller by following the steps described below
to avoid installation faults.
When mounting the controller with screws, make sure
to use screws that suit the attachment material
(use screws with 4 mm shaft and max. 8 mm head
diameter, no counter sunk). Keep in mind that the
screws also have to carry the force applied by the
wiring.
Make sure that the ventilator slits on the sides
are unobstructed.
A DIN Rail mounting plate is available as an accessory (CX-DR2). This
allows mounting the controller on a standard 35mm DIN rail. Place the
controller on the mounting plate, and use the screws supplied with the
mounting plate to fix it to the controller.
Connect the wires leading to the battery with
correct polarity. To avoid any voltage on the
wires, first connect the controller, then the
battery. Keep in mind the recommended wire length
(min. 30 to max approx. 100 cm) and the wire size:
CA06-2: min. 2.5 mm
