is danger of gas or dust explosion or area in which ignition-protected equipment is required.
Warnings regarding the use of batteries
1 Someone should be within range of your voice or close enough to come to your aid when you
work near a battery.
2 Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or
eyes.
3 Wear complete eye protection and clothing protection. Avoid touching eyes while working near
battery.
4 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.
5 NEVER smoke or allow a spark or flame in vicinity of battery or engine.
6 Do not short circuit batteries, as this may result in explosion and fire hazard! Be extra cautious
to reduce risk of dropping a metal tool onto battery. It might spark or short-circuit battery or
other electrical part that may cause explosion.
7 Remove personal metal items such as rings, bracelets, necklaces, and watches when working
with a battery. A battery can produce a short-circuit current high enough to weld a ring or the
like to metal, causing a severe burn.

Mac Plus –User and Installation Manual
Remote switch input
The remote switch input (pin 4 of the Accessories connector) can be used to enable and disable the
battery charger. In a vehicle application, it is recommended to connect the engine run signal. This
way, the charger is used when the engine is running and the alternator is charging. The engine run
signal can be provided in different ways. For details contact your vehicle distributor.
The remote input accepts two different enable levels:
•active low, connect to ground (between 0 and 0.5 V)
•active high, connect to + battery voltage (between 3 and 32 V)
Active low means active when input is low. Active high means active when input is high.
The remote switch input configuration can be done by DIP switch (see chapter 7) or by MasterBus
(see chapter 9 and 10).
Battery temperature sensor (included)
By installing the Mastervolt temperature sensor, the charge voltages are automatically adapted for
deviating temperatures.
Figure 1. Temperature compensated charging
When the battery temperature is low, the charge voltage increases. In case the battery temperature
is high, the charge voltage is decreased. Over charge and gassing are prevented this way. This will
extend the life of your battery.
Voltage drop compensation
The Mac Plus can compensate the voltage drop occurring over the output cables. For this purpose,
the Mac Plus is equipped with terminals for voltage sense wires. Use 0,75 mm2 [AWG 18], preferably
red and black wire and protect these with a 2 A fuses slow blow. Pay good attention to the polarity
of the wires.
In order to accurately measure the battery voltage, connect the voltage sense wires as close to the
battery poles as possible. The positive and negative voltage sense wires must be connected. Cable
losses will be compensated up to a maximum of 2.5 V.

7. Configuration –DIP switches
The Mac Plus settings can be adjusted in two ways:
•By means of DIP switches;
•Via the MasterBus network (with a remote-control panel, or a PC with MasterAdjust software
connected via a USB Interface); see chapter 9 and 10.
This chapter only describes the DIP switch settings.
Note: DIP switch settings overrule MasterBus settings. If DIP switches are not in their default
setting, the corresponding MasterBus setting is grayed out.
CAUTION!
Incorrect settings of the Mac Plus can cause serious damage to your batteries and/or the
connected load! Adjustments of settings may be undertaken by authorized personnel only!
Use a small screwdriver to carefully set the required
settings. You may need to remove the MasterBus
cables (or Terminator) to be able to access the DIP
switches.
For an overview of the various DIP switch settings,

9. MasterBus
What is MasterBus
All devices that are suitable for MasterBus are marked by the MasterBus symbol
MasterBus is a fully decentralized data network for communication between the
different Mastervolt system devices. It is a CAN-bus based communication network
which has proven itself as a reliable bus-system in automotive applications. MasterBus is used as
power management system for all connected devices, such as the inverter, battery charger,
generator and many more. This gives the possibility for communication between the connected
devices, for instance to start the generator when the batteries are low.
MasterBus reduces complexity of electrical systems by using UTP patch cables. All system
components are simply chained together. Therefore, each device is equipped with two MasterBus
data ports. When two or more devices are connected to each other through these data ports, they
form a local data network, called the MasterBus. The results are a reduction of material costs as
only a few electrical cables are needed and less installation time.
For central monitoring and control of the connected devices Mastervolt offers a wide range of panels
which show full status information of your electrical system at a glance and a push of a button. See
www.mastervolt.com for all available options.
New devices can be added to the existing network in a very easy way by just extending the network.
This gives the MasterBus network a high degree of flexibility for extended system configuration, not
only today, but in the future as well!
Mastervolt also offers several interfaces, making even non-MasterBus devices suitable to operate in
the MasterBus network.
How to set up a MasterBus network
Each device that is suitable for the MasterBus network is equipped with two data ports. When two or
more devices are connected to each other through these ports, they form a local data network,
called the MasterBus. Keep the following rules in mind:
˗Connections between the devices are made by standard MasterBus cables (straight UTP).
Mastervolt can supply these cables.
˗As with all high-speed data networks, MasterBus needs a terminating device on both ends of
the network.
˗Up to 63 MasterBus devices can be connected together.
˗The electric power for the network comes from the connected devices. At least one device in
the network should have powering capabilities (see specifications). One powering device can
power up to three non-powering devices. As all powering devices are galvanically isolated,
multiple powering devices are allowed. Spread the powering devices over the network.
˗Do not make ring networks.
˗Do not make T-connections in the network.
For more details on networks, please contact your Mastervolt supplier.
