1. Safety Instructions

1.1 Refer installation and servicing to qualified service personnel. High
voltage is present inside unit. Incorrect installation or use may result in
risk of electric shock or fire. No user serviceable parts in this unit.

1.2 Remove all sources of power , photovoltaic and battery before servicing
or installing.

1.3 WARNING - RISK OF EXPLOSIVE GASES

a) Working in the vicinity of lead-acid batteries is dangerous. Batteries produce explosive
gasses during normal battery operation.
b) To reduce risk of battery explosion, follow these instructions and those published by
battery manufacturer and manufacturer of any equipment you intend to use in vicinity of
battery.

1.4 PERSONAL PRECAUTIONS

a) Someone should be within range of your voice or close enough to come to your aid when
you work near a lead acid battery.
b) Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing
or eyes.
c) Wear complete eye protection and clothing protection. Avoid touching eyes while working
near battery.
d) If battery acid contacts skin or clothing, wash immediately with soap and water. If acid
enters eye, immediately flood eye with running cold water for at least 10 minutes and get
medical attention immediately.
e) NEVER smoke or allow a spark or flame in vicinity of battery.
f) Be extra cautious to reduce risk of dropping metal tool onto battery. It might spark or
short circuit battery or other electrical part that may cause explosion.
g) Remove personal metal items such as rings, bracelets, necklaces, and watches when
working with a lead-acid battery. A lead-acid battery can produce a short circuit current
high enough to weld a ring or the like to metal, causing a severe burn.

1.5 PREPARING TO CHARGE

a) Never charge a frozen battery.
b) Be sure battery is mounted in a well ventilated compartment.

1.6 CHARGER LOCATION & INSTALLATION

a) Controller employs components that tend to produce arcs or sparks. NEVER install in
battery compartment or in the presence of explosive gases.
b) Protect all wiring from physical damage, vibration and excessive heat.
c) Insure that the controller is properly setup for the battery being charged.
d) Do not expose controller to rain or snow.
e) Insure all terminating connections are clean and tight to prevent arcing and overheating.
f) Charging system must be properly installed as described in these instructions prior to
operation.
g) Do not connect to a PV array capable of producing greater than 24 amps of short circuit
current @ 25 °C.

1.7 Use the scope

This SHS050 is applicable to the family usually power supply, such as the saving lamp, the
direct current radio the small power of etc. solar cell outside, other equipments( such as:
Power box, battery) under the condition of have no protection measure, can install only
indoors.

2.2 Solar Charge Controller CA06-2

Please read the charge controller manual carefully taking special note of the safety and
Usage recommendations at the end. The manua l g i v e s im portant recommen d a t ions for
installing, using and programming as well as a troubleshooting guide for potential
problems with the controller.

WARNING :Do not use over 72W loads forever.

It is a new CA controller; you will own a state-of-the art device which was developed according to the latest
available technical standards. It comes with a number of outstanding features, such as:

z 3 LEDs for a clear, readable display of the state of charge
z 16 mm

2

connector clamps

z Temperature compensation
z Electronic protection without fuses

This manual gives important recommendations for installing, using and configuration as well as remedies in
case of problems with the controller. Read it carefully in your own interest. Please take note of the safety
and usage recommendations at the end of this manual.
Description of Functions
z The charge controller protects the battery from being overcharged by the solar array and from being

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

2

WARNING: If the battery is connected with reverse polarity, the charge
controller will also give the wrong polarity on the load terminals.
Never connect loads in this situation!

Connect the wires leading to the solar array with
correct polarity. To avoid any voltage on the
wires, first connect the controller, then the solar
array. Keep in mind the recommended wire size:

CA06-2: min. 2.5 mm

2

REMARK: place positive and negative wires leading to the solar
generator close to each other to minimize electromagnetic effects.

Connect the wires leading to the loads with correct
polarity. To avoid any voltage on the wires, first
connect the wire to the load, then to the
controller. Keep in mind the recommended wire size:

CA06-2: min. 2.5 mm

Starting up the Controller
System Voltage

The controller is intended for use at 12 V system voltage.

Battery Type

The controller does not generate an equalization charge, and is therefore suitable for use with lead acid
batteries with liquid electrolyte (vented battery) and lead acid batteries with solid electrolyte ('gel' or
'fleece' type).
Recommendations for Use
The controller warms up slightly during normal operation.

The controller does not need any maintenance or service. Remove dust with a dry tissue.
It is important that the battery gets fully charged frequently (at least monthly). Otherwise the battery

will be permanently damaged.
A battery can only be fully charged if not too much energy is drawn during charging. Keep that in mind,

especially if you install additional loads.
Display Functions in normal operation
The controller is equipped with 3 LEDs for display of the operating status.

Charge display

Battery voltage display

Load status display

In normal operation mode, the controller displays the charging status, the status of battery voltage and the
status of the load output.
