WARNING
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.
CAUTION
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. GROUNDING AND AC POWER CORD CONNECTION
INSTRUCTIONS — Charger shall be grounded to reduce risk
of electric shock. Charger is equipped with an electric cord
having an equipment-grounding conductor and a grounding
plug. The plug is to be plugged into an outlet that is properly
installed and grounded in accordance with all local codes
and ordinances.
DANGER — Do not alter AC cord or plug provided — where
it does not fit outlet, have proper outlet installed by a
qualified electrician. Improper connection increases the
risk of an electric shock. (If the supply cord is damaged, it
must be replaced by the genuine REDARC part 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. The fuse must be UL Listed / UL
Recognized.
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 Sealed Lead Acid (SLA), Lead Crystal, Calcium
Content, Gel, Absorbent Glass Mat (AGM), Start Lighting
Ignition (SLI), Deep-Cycle or Lithium Iron Phosphate type
12V batteries.
8. Do NOT try to charge non-rechargeable batteries.
9. 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.
10. NEVER smoke or allow a spark or flame in vicinity of a
battery. This may cause the battery to explode.
11. Be extra cautious so as to reduce the risk of dropping a
metal tool onto a vehicle battery. Doing so might cause the

3
battery to spark or might short-circuit the battery or other
electrical parts that may cause an explosion.
12. Remove personal metal items such as rings, bracelets,
necklaces, and watches when working with batteries. A
battery can produce a short-circuit current high enough to
weld a ring or the like to metal, causing a severe burn.
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.
NOTICE
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 to the
base unit at all times.
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
there is a valid charging source and that all loads are
disconnected from the house battery. 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 its 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.

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 Figure 1.5.1). 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 1.5.1.
NOTICE
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 travel trailer or RV 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, Battery Test, Equalize**, Float and Maintenance stages (see Figure 1.5.2).
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 (3.7) of this manual.
Unlike Touring mode, Storage mode does not continue to cycle through charge profiles. This means that
when the charging process is completed, The Manager30 in Storage mode will always remain in either
Float or Maintenance stages. Float stage provides the house battery with a ‘trickle’ charge whenever the
house battery voltage drops below a predetermined threshold, to ensure that 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.
Valid charging sources for The Manager30 while in Storage mode include AC Shore Power and Solar.
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.
NOTICE
When using the charger in Storage mode, make sure that there is a valid charging source and that all
loads are disconnected from the house battery. 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 nonessential 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 40Ah in capacity. When the charge current is set below the maximum
30 Amps, the current supplied to charge the battery is restricted to the user setting. Any excess current is
available 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. AC Mains/Shore Power,).
Priority is given to Solar then to AC Mains 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 95 °F (35 °C) and does not exceed a
maximum of 140 °F (60 °C). The Manager30 must not be mounted in the vehicle engine bay.
The Main Unit must not be installed in a location with any less than 4" (100mm) 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 6 ½ feet (2m).
The Main Unit must be mounted to a flat, solid support using ¼" (M6) sized screws or bolts, using all four
mounting holes.
NOTICE
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 optimize airflow past the heatsink. Mounting the

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.
The Battery Sensor should be mounted to a solid surface using two suitably sized screws (¼" or M6
recommended) for attachment. Figure 2.2.3.1 illustrates how to mount the Battery Sensor.
FIGURE 2.2.3.1: Mounting the Battery Sensor
2.3 DC Cable Size Requirements
CAUTION
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 50A from the Vehicle Battery (which may be several feet/
meters from its installation location) and is limited to 30A 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
minimize voltage drop and efficiency losses.

The AC/Shore Power power connection must be connected to a grounded 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
the genuine REDARC part or assembly available from the manufacturer or service agent).
CAUTION
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 (i.e. switches the Load Disconnect input to ground when
active and is open circuit when inactive) to activate a relay for disconnection of any loads running from
the house battery. The relay must be 12V with a maximum coil current of 1A and resistor or diode
suppression is recommended. The Load Disconnect feature must be activated in the User Menu as
explained in Section 3.5 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 vehicles with Variable Voltage
alternators to trigger the DC Input. Figure 2.4.4.2 shows how to wire the Ignition Trigger wire.
The Ignition Trigger feature must be activated in the User Menu as explained in Section 3.5 of this
manual.
