SAVE THESE INSTRUCTIONS - This manual contains IMPORTANT SAFETY INSTRUCTIONS for The
Manager30 battery management system.
DO NOT OPERATE THE BATTERY CHARGER UNLESS YOU HAVE READ AND UNDERSTOOD THIS MANUAL
AND THE CHARGER IS INSTALLED AS PER THESE INSTALLATION INSTRUCTIONS. REDARC RECOMMENDS
THAT THE CHARGER BE INSTALLED BY A SUITABLY QUALIFIED PERSON.
RISK OF EXPLOSIVE GASES:
WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE
GASES DURING NORMAL OPERATION. FOR THIS REASON, IT IS OF UTMOST IMPORTANCE THAT YOU
FOLLOW THE INSTRUCTIONS EACH TIME YOU USE THE CHARGER.
1. The Battery Charger should not be used by persons (including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge, unless they are supervised or have been instructed
on how to use the appliance by a person responsible for their safety. Children should be supervised to ensure
that they do not play with the Battery Charger.
2. Do NOT alter or disassemble the Battery Charger under any circumstances. All services or repairs must be
returned to REDARC for repair. Incorrect handling or reassembly may result in a risk of electric shock or fire and
may void the unit warranty.
3. Use of an attachment not recommended or sold by REDARC may result in a risk of fire, electric shock, or injury
to persons.
4. The AC power connection must be connected to an earthed socket outlet. Do not use the AC input if the cord is
damaged. Use of a non-genuine or damaged AC input cord may result in a risk of fire, electric shock, or injury
to persons. (If the supply cord is damaged, it must be replaced by a special cord or assembly available from the
manufacturer or service agent).
5. Cable and fuse sizes are specified by various codes and standards which depend on the type of vehicle the
Battery Charger is installed into. Selecting the wrong cable or fuse size could result in harm to the installer
or user and/or damage to the Battery Charger or other equipment installed in the system. The installer is
responsible for ensuring that the correct cable and fuse sizes are used when installing this Battery Charger.
6. When charging a battery, make sure the settings at the Battery Setup menu on the Remote Monitor are correct
for the type of battery under charge. Charging a battery with the wrong profile may cause the Battery Charger
to indicate a fault or give misleading results and cause injury to persons, damage to the Battery Charger and/or
property. Noticeable oscillations between Boost and Absorption stages indicate the wrong choice of battery type.
Check and adjust battery type. If you are unsure of the battery type or settings to use, set to the Gel setting.
7. Only use the Battery Charger for charging Standard Automotive Lead Acid, Calcium Content, Gel, AGM, SLI,
Deep Cycle or Lithium Iron Phosphate type 12V batteries.

WARNINGS & SAFETY INSTRUCTIONS
8. When using the Battery Charger to charge a Lithium Iron Phosphate battery, only batteries that feature an inbuilt
battery management system featuring inbuilt under and over voltage protection and cell balancing are suitable.
9. NEVER smoke or allow a spark or flame in vicinity of battery. This may cause the battery to explode.
10. Be extra cautious so as to reduce the risk of dropping a metal tool onto a vehicle battery. Doing so might cause
the battery to spark or might short-circuit the battery or other electrical parts that may cause an explosion.
11. 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.
12. A SPARK NEAR A BATTERY MAY CAUSE THE BATTERY TO EXPLODE. TO REDUCE THE RISK OF A SPARK
NEAR A BATTERY WHEN CONNECTING THE BATTERY INSTALLED IN A VEHICLE TO THE BATTERY CHARGER,
ALWAYS DO THE FOLLOWING:
Always wire the Output Connector before connecting it to the Battery Charger. During connection of the unit,
the Battery Output (positive) must be connected first, followed by the Ground (chassis) terminal. The chassis
connection should be made away from the battery and fuel lines. DC Input (positive) should be connected
last. Once all connections are wired to the Output Connector, plug the connector into the Main Unit.
When disconnecting the Battery Charger, remove the AC Connector first, followed by the CAN connection then
the Output Connector from the Main Unit. The DC Input should be disconnected next, followed by the Ground
(chassis) connection, then the Battery Output connection if complete removal is necessary.
13. PERSONAL SAFETY PRECAUTIONS
To assist with the safe operation and use of the Battery Charger:
a) Consider having someone close by to come to your aid when you are using the Battery Charger.
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 a battery.
d) If battery acid contacts your skin or clothing, remove the affected clothing and wash the affected area of your
skin immediately with soap and water. If battery acid enters your eye, immediately flood the eye with running
cold water for at least 10 minutes and seek medical assistance immediately.
e) To improve user safety it is recommended to control the charger and monitor the charging process using the
remote away from the vicinity of the battery being charged.
1. Do NOT connect computers or IT equipment to the Charger front panel connector or remote. Damage may occur.
2. It is recommended to leave the remote connected at all times to the base unit.
3. The Main Unit must be fixed using suitable screw mounts. Failure to adequately mount the unit, such as using
adhesives to mount the unit will result in unreliable operation of the charger.
4. When using the charger in Storage mode, make sure that all loads are disconnected from the house battery
under charge. Failure to do so may cause the house battery to be under charged, give false readings on the
State of Charge indicator and possibly cause damage to any loads connected.
5. A partially shaded panel (or low-light conditions such as dawn or dusk) will increase the target solar panel
voltage level to match the maximum power point. In this situation solar will be selected as a source however
little or no current will be flowing into the battery.
6. Modification of the ‘Advanced Settings’ menu items affect the way the Battery Charger responds to charging situations.
Modification of these settings may result in the Battery Charger not functioning at 100% of its capacity. These settings
should only be modified if absolutely necessary and when the effects of the changes are 100% understood.
7. Touring mode will achieve it’s best charge level if a Storage mode charge has been recently performed.
8. It is the installers responsibility to ensure their installation complies with any applicable legal and regulatory
requirements. Within Australia, installers may wish to consult AS/NZS 3001 as one potentially relevant standard.

1 INTRODUCTION
1.5 Multi-stage Charging Process
The Manager30 incorporates two different multi-stage charging profiles – Touring
(3-stage) and Storage (8-stage) – which can be selected in the Battery Mode
menu on the Remote Monitor.
Touring Mode
Touring mode is designed for use when ‘on the road’. Touring mode offers a
3-stage charging profile consisting of Boost, Absorption and Float stages (see
Figure1.4.1). In Touring mode, the house battery is monitored to detect only a
limited number of faults such as short circuit, over current and over voltage. This
allows The Manager30 to operate correctly even when loads are connected to the
house battery. This mode will always produce an output (unless a fault condition
is detected) and will cycle through the three stages as required to maintain the
house battery as outlined in Figure 1.4.1.
Touring mode will achieve its best charge level if a Storage mode charge has been
recently performed.

1 INTRODUCTION
Storage Mode
Storage mode is designed to charge the house battery to its optimal level and
maintain that level while your caravan is in storage. This mode requires all loads
to be switched off or disconnected from the house battery before charging. It
uses a 8-stage* charging profile consisting of Desulphation*, Soft Start, Boost,
Absorption,BatteryTest,Equalise*,Floatand Maintenance stages (seeFigure1.4.2).
Storage mode is designed to detect a wide range of battery fault conditions, for
more information on these fault conditions, please refer to the Troubleshooting
section of this manual. Unlike Touring mode, Storage mode does not cycle. This
means that when the charging process is completed, The Manager30 will always
remain in either Float or Maintenance stages. Float stage will provide the house
battery with a ‘trickle’ charge whenever the house battery voltage drops below a
predetermined threshold to ensure the battery stays charged. Maintenance stage
turns The Manager30 output off, but continues to monitor the house battery and
will revert to Float stage when necessary.
NOTE: If The Manager30 is set to Storage mode and the vehicle is started
The Manager30 will automatically switch to Touring mode once it senses an
increase in input voltage from the alternator.
When using the charger in Storage mode, make sure that all loads are disconnected from
the house battery under charge. Failure to do so may cause the house battery to be under
charged, give false readings on the State of Charge indicator and possibly cause damage
to any loads connected.

1 INTRODUCTION
IMPORTANT
When The Manager30 is set to ‘Storage’ mode and no valid charging sources are
connected, it will enter a ‘Sleep’ mode 30 seconds after the last user interaction.
The sleep mode is designed to limit the amount of current drawn from the output
battery by the system whilst in Storage mode and does this by switching the
screen and all non-essential functions off. The Manager30 will ‘wake-up’ from
its Sleep mode if a button is pushed or if any valid input source is sensed, though
this may take 30-60 seconds to occur after the source is connected.
1.6 Maximum Charge Current Setting
The Manager30 allows the user to set the maximum charge current for their
battery, making it suitable for charging batteries as small as 40Ah in capacity.
When the charge current is set below the maximum 30Amps, the current supplied
to charge the battery is restricted to the user setting. Any excess current is used
to power loads running from the battery under charge.
If no loads are running from the battery, total current from The Manager30 will be
restricted to the level set by the user.
1.7 Green Power Priority
The Manager30 is designed to charge from multiple sources simultaneously
to charge the auxiliary/house battery. If the Solar power input is available the
maximum available solar power will be used before topping up the output
charging current from another source if available (e.g. mains). Priority is given to
Solar then to AC Mains power, then to DC Vehicle power.

2.2.1 Mounting the Main Unit
Do NOT expose the Main Unit to rain, snow, spray or bilge water. For optimum
operation,The Manager30 should be mounted where the temperature is nominally
below 35°C and does not exceed a maximum of 60°C.
The Main Unit must not be installed in a location with any less than 10cm
clearance at the top of the Main Unit, to allow for airflow across the heatsink fins.
The Main Unit should be installed as close as possible to the house battery. The
cable length should be less than 2m.
The Main Unit must be mounted to a flat, solid support using M6 sized screws or
bolts, using all four mounting holes.
The Main Unit must be fixed using suitable screw mounts. Failure to adequately mount
the unit, such as using adhesives to mount the unit will result in unreliable operation of
the charger.
REDARC recommends that the Main Unit be mounted to optimise airflow past the
heatsink. Mounting the unit horizontally (see Figure 2.2.1.1) is recommended and
mounting vertically (see Figure 2.2.1.2) is still acceptable. Do NOT mount the unit

2 INSTALLATION GUIDE
2.2.3 Mounting the Battery Sensor
The length of cables on the Battery Sensor to connect to the Main Unit and the
House Battery will dictate the allowable mounting distance from the battery
however REDARC recommend mounting the Battery Sensor as close to the Main
Unit as possible.
The Battery Sensor should be mounted to a solid surface using two suitably sized
screws for attachment.
Figure 2.2.3.1 illustrates how to mount the Battery Sensor.
2.3 DC Cable Size Requirements
Cable and fuse sizes are specified by various codes and standards which depend on the
type of vehicle the Battery Charger is installed into. Selecting the wrong cable or fuse
size could result in harm to the installer or user and/or damage to The Manager30 or
other equipment installed in the system. The installer is responsible for ensuring that the
correct cable and fuse sizes are used when installing the Battery Charger.
The Manager30 is capable of drawing up to 50A from the Vehicle Battery (which
may be several metres from its installation location) and is limited to 30A output
to the House Battery. The installer needs to ensure the appropriate cable is used
to connect the positive and negative connections of The Manager30 to both the
Vehicle Battery and the House Battery. The Manager30 will operate with less
efficient cabling however for best performance, high-quality cable connections
should be used to minimise voltage drop and efficiency losses.

2 INSTALLATION GUIDE
2.4 The Manager30 Wiring Connections
REDARC recommends that this unit be installed by a suitably qualified person.
The AC power connection must be connected to an earthed socket outlet. Do not use
The Manager30 AC input if the cord is damaged. Use of a non-genuine or damaged AC
input cord may result in a risk of fire, electric shock, or injury to persons. (If the supply
cord is damaged, it must be replaced by a special cord or assembly available from the
manufacturer or service agent).
Always wire the Output Connector before connecting it to the Main Unit. During
connection of the unit, the Battery Output (positive) must be connected first, followed by
the Ground (chassis) terminal. The chassis connection should be made away from the
battery and fuel lines. DC Input (positive) should be connected last. Once all connections
are wired to the Output Connector, plug the connector into the Main Unit.
When disconnecting remove the Output Connector from the Main Unit first. The DC Input
should be disconnected next, followed by the Ground (chassis) connection, then the
Battery Output connection.
2.4.1 Load Disconnect Feature
The Load Disconnect wire is a ground switch to activate a relay for disconnection
of any loads running from the house battery. The relay must be 12V with a
maximum coil current of 1A and resistor or diode suppresion is recommended.
The Load Disconnect feature must be activated in the User Menu as explained in
section 3.3 of this manual.
2.4.2 Ignition Trigger Feature
The Ignition Trigger wire is used to turn the DC charging source on with ignition.
In most circumstances this wire does not need to be connected. This feature is
designed to allow vehicle with Variable Voltage alternators to trigger the DC Input.
Figure 2.4.2 shows how to wire the Ignition Trigger wire.
The Ignition Trigger feature must be activated in the User Menu as explained in
section 3.3 of this manual. 18
