Safety Instructions
Before connecting and running your Sterling alternator-to-
battery charger, read the complete instructions and all
cautionary labels on the unit and on the batteries. Only a
correct installation according to these instructions will let
you take full advantage of your alternator-to-battery
charger.
General Precautions
Always install the unit in a dry, cool and well-ventilated place.
Any contact with water and heavy humidity has to be avoided.
Do not cover the fans to prevent the unit from overheating.
Make sure all cables have the appropriate size and are in good
condition. Do not run the unit with cables that are damaged or
otherwise inappropriate.
Precautions against Gas Explosions
The alternator-to-battery charger contains electrical
components which may produce sparks. In order to avoid the
risk of fire or explosion, do not install the unit in rooms
containing batteries or highly inflammable materials or in any
place requiring explosion-proof equipment. This includes any
room with petrol, gas or diesel driven engines or with tanks or
piping used for any such substance.
Before starting to install the charger please ensure that there is
sufficient ventilation. In order to prevent the formation of
explosive gases make sure that the batteries have not been
charged for at least 4 hours prior to installation.
Precautions when Handling Batteries
Someone should be within earshot, i.e. close enough to come
to your aid when working near a lead-acid battery. Have plenty
of water and soap nearby in case battery acid comes in
contact with skin, clothes or eyes. Wear complete eye
protection and protective clothing. Avoid touching the eyes
while working with a battery.
If battery acid contacts skin or clothing, wash immediately with
soap and water. If acid enters the eye(s), flood eye(s) with
running cold water for at least 10 minutes and seek medical
attention immediately.
Never smoke or allow a spark or flame in the vicinity of a
battery or the engine.
Work with extra caution to reduce the risk of dropping a metal
tool onto a battery. It may create sparks or short-circuit the
battery or other electrical parts that may cause an explosion.
Remove all personal metal items such as rings, bracelets,
necklaces, watches and jewellery when working near a battery.
A battery can produce a short-circuit current high enough to
weld a ring or any other metal which will lead to serious burns.
Never charge a frozen battery.
General Overview
The Sterling alternator-to-battery charger is a fully automatic,
electronic multi-stage split-charge system which charges two
banks of batteries from one or more alternators. It combines an
advanced split charge diode system with a powerful voltage
amplifier. The unit has one input to connect to one or more
alternators and two outputs to charge two different battery
banks.
The output marked "starter battery" is a straight channel
through a diode; this is the channel that is connected to the
boat / vehicle engine system. In order to avoid any conflicts
with an electronic engine management system, there is no
boost function on this channel.

The output marked "domestic battery" comprises an intelligent,
software-controlled boost function which charges the domestic
battery bank up to five times faster and much more efficient than a
standard alternator could do. In addition, the batteries will take in up
to 50% more charge current, allowing you to utilise their full capacity.
While the alternator-to-battery charger greatly improves the charging
of the domestic battery bank, the starter battery has always priority,
ensuring that the engine can be started at any time. Under no
circumstances will the system allow the starter battery to drop below
13V.
Additional functions protect your electrical system and your batteries
from possible faults such as overcharging or overtemperature. Any
fault on the system will be indicated by a number of LEDs or on the
optional remote control unit.
How it works
In order to maximise the alternator output current, the alternator-to-
battery charger pulls the alternator output voltage down to about
13V. Then this low voltage is amplified to a higher voltage suitable
for effective battery charging, i.e. 14.1V to 14.8V. The unit's
intelligent software automatically calculates the optimum charge
cycle and absorption time. When the batteries have been fully
charged, the voltage is reduced to float voltage (appr. 13.5V to
13.8V).
Easy installation: It could not be easier. For the basic system only
4 connections are required: one from the alternator(s), one to each
battery bank and one to the common negative. Apart from the
additional negative connection most of these cables will be on board
anyway.
Advanced charging technology: Intelligent, software-controlled,
4step charging of the domestic battery including temperature
compensation.
No interference with engine electronics: Because the system
does not increase the voltage of the starter battery there is no risk of
problems with the electronic engine management system.
No work on the alternator required: Absolutely no changes to the
alternator are required. As a result no warranty conflicts can arise.
Suitable for multiple alternators: Unlike other systems the
alternator-to-battery charger can be used simultaneously on more
than one alternator, saving even more installation work and money.
Starter battery priority: The system ensures that the starter battery
is always kept in operational condition.
Intelligent fault protection: The unit comprises multiple safety
features and fault indicators. Even in the unlikely event of a
complete failure, the unit will still work as a split charge diode.
Enhanced installation options: The unit comes with temperature
sensors for the battery and the alternator. It can be enhanced by an
optional remote control.
Important: These guidelines refer to the connections that have
to be made for the correct installation of the Sterling Alternator-
to-Battery Charger. On an existing system you may also be
required to remove some of the connections that were used to
charge the batteries prior to the installation of the unit.
Install the unit in a cool and well-ventilated position close to the
alternator(s). Also, the installation point has to be dry and free from
heavy condensation since the unit is not waterproof. Do not fit it in a
closed box as this might lead to overheating of the unit and reduced
performance.
The unit has three temperature-controlled fans. Therefore they will
