1. Introduction
You chose PowerPlex®, a comprehensive, future-oriented on-board system which combines safety, user
convenience and reliability. It is a decentralised power distribution and control system, regulating, controlling and
monitoring various loads, switches and sensors and connecting them via CAN. All PowerPlex®modules ensure
reliable control and monitoring of the electrical installations on board, either alone or in combination with other
PowerPlex®components. Besides the protection against overcurrent, they allow readout of data of the connected
level sensors and temperature sensors as well as of shunts.
By means of the PowerPlex®configuration software, the application-specific logics for power distribution, power
control and power monitoring will be defined, stored or adjusted. Communication takes place via the PowerPlex®
CAN, based on SAE J1939.
Thanks to its system properties PowerPlex®is the perfect solution for smart electrical networks on boats and in
vehicles. Typical applications include:
•Buses, special vehicles, mobile homes etc.
•Watercraft, e.g. leisure boats, workboats
Benefits for the OEM
The E-T-A PowerPlex®system allows switching and controlling of various loads, timer functions, real load status
indication, overcurrent protection and wire break detection. Each function can be configured separately to meet
the requirements of the loads.
Based on the CAN communication the PowerPlex®system allows to make individual wiring between load and
control unit a thing of the past. The transmission of switch commands and status information is based on the peer-
to-peer CANbus communication. A direct cable connection between the actuator, e.g. a light switch, and the load,
e.g. a lamp, isno longer required. The obvious advantages for the OEM include thereduced wiring and production
costs as well as a convenient system setup by means of a Windows based configuration software. All control
functions of the system are freelyconfigurable with regard to complexity and size of the system. Changeor system
extension at a later date are also extremely easy.
PowerPlex®Scope of operation –PowerPlex®takes over the following tasks:
•Distributes the DC 12 V or DC 24 V power supply to all spots of the boat where loads are installed, such
as lighting and heating control, bilge and water pumps, windscreen wiper motors etc.
•Collects all status information of all sensors and actuators everywhere in the vehicle, such temperature
and tank level measuring points, ON/OFF status signals of the actuators.
•Switches devices and equipment ON and OFF, according to selectable, pre-set scenarios, at the touch
of a button.
•Monitors devices and equipment regarding their out-of-range conditions, indicates possible failures and
responds by reversing the pertinent control unit, as e.g. switching on a pump, if the water tank level falls
below a certain limit.
•Protects devices and equipment against hazardous overcurrent and short circuit by isolating the faulty
load from the system and failure indication to the system.
•Offers back-up protection and switching in the improbable case of a PowerPlex®system or component
failures.

2. System components: Overview
The PowerPlex®system of E-T-A is a comprehensive on-board system combining safety, convenience and
reliability. PowerPlex®allows individual and flexible concepts of switching the illumination, acoustic and special
signals and lots more. It automatically switches loads and immediately indicates undesired conditions of the
devices or of the entire electrical installation. Thus it is ensured, that everything works precisely - which is
reassuring, asthe loadsoften are not inplain sight.E-T-A PowerPlex®is adecentralised power distribution system
with electronic protection –clearly reflecting trends of the future.
Fig. 1 and Fig. 2 show typically PowerPlex®solutions with an application-specific number of PowerPlex®
components - modules and control units –installed at various positions.

PowerPlex®communication is based on the CAN bus principle by means of “nodes”, which communicate with
each other via a serial 2-wire connection. Hence the key components of a PowerPlex®system are these nodes
distributed over the vehicle or boat. The overall PowerPlex®term for these interconnected nodes is “module".
Various hardware components are required for installation and start-up of a PowerPlex®system:
Please check the delivered components upon receipt about completeness. You require the following hardware
components for installation and start-up of a PowerPlex®system:
•one or more PowerPlex® modules (e.g. DC Power Module, DC Mini Module) that meet application-specific
requirements
•USB-CAN converters (cable and driver) for transferring the configuration
•USB cables for the USB service interface for transferring application-specific user interfaces onto
PowerPlex®Touch Panels.
In addition, you require a CAN bus cable for connecting the PowerPlex®components to the bus. Many
manufacturers offer standard cables for thispurpose. For more information on the required cable properties please
see chapter 0 of the manual.
PowerPlex®reliably and precisely connects, regulates, controls and monitors electrical loads, switches and
sensors via CAN. It controls status indications, operating conditions and execution of commands. Perfectly
matched software and hardware components offer a comprehensive total solution with maximum potential of
individualisation.
Each module protects the loads and cable harnesses against overcurrent. In addition the modules collect data of
level sensors and temperature sensors as well as of shunts. Usually a PowerPlex®system consists of several
modules of different kinds. The selection depends on the size of the electrical system to be monitored and
controlled as well as of the current ratings of the loads.
Use our PowerPlex®Configuration Software to “programme” various control configurations. As requested, you
can store them on the computer and load them into various PowerPlex®control systems. As soon as a
PowerPlex®configuration has been completed, it will be transferred to the PowerPlex®modules (”nodes”) via the
CAN bus interface. Via this CAN bus interface you also connect the PowerPlex®software for testing, analysing
and debugging purposes of the PowerPlex®installation.

3. PowerPlex®System: General
3.1.PowerPlex®Modules
PowerPlex®modules are the key components of a PowerPlex®network. According to the CAN bus terminology
they are the “nodes” of the network and form the points of switching, transmission and control.
PowerPlex®for DCsystem include high-end power semi-conductors with integral protective elements for switching
and protection of electrical loads. The modules are free of mechanical components and thus insusceptible to wear
and shock and vibration resistant.
E-T-A offers various PowerPlex®modules for DC 12 V and DC 24 V systems. gives an example of the difference
between two modules.

Table 3: Different PowerPlex® Modules
3.2.PowerPlex®CAN Bus
A PowerPlex® network can embrace up to 30 different PowerPlex® modules. The smallest PowerPlex®system
would consist of two modules communicating via the CAN bus cable (see Fig. 4).
The loads controlled by the modules - in this case a light and bilge pump - are normally installed at some place in
the vehicle which may not be necessarily close to the input signal. The decentralised control structure of
PowerPlex®allows monitoring and switching of the devices anywhere on the vehicle or boat from any chosen
installation site.
A level sensor monitors the bilge and supplies the analog information on module 1. From there the information is
transferred to module 2 via the CAN bus. As soon as the measured analog input value (i.e. the “pumping level”)
has exceeded a pre-set limit value, module 2 will send a switch command to the load (i.e. the “bilge pump”) so as
to switch on the pump and to reduce the water level of the bilge back to an acceptable level. The status information
of the bilge pump will be sent back to module 1 to switch on the display “bilge pump running”.
In addition, module 2 monitors the position of a light switch –ON or OFF –at one of the digital inputs and sends
the switching signal to module 1, which switches the light ON or OFF depending on the switching status.

12
Fig. 4: Two PowerPlex® modules connected via CAN bus cable
An example demonstrates the principle of using the sensor and switching signal information at the module inputs
as well as the sending, switching or the display of commands to the outputs of the same or a different module.
A typical PowerPlex®control system will of course connect a much higher number of modules and their inputs
and outputs which will be distributed over the entire vehicle. Fig. 5 shows the electrical connection of several
PowerPlex®modules in a serial CAN bus topology. Each module must be connected to the DC voltage supply
and the CAN bus.
Fig. 5: Various PowerPlex® modules connected via serial CAN bus topology
Note
The firstand last Modules of the CANbustopology mustbe connected with a 120 Ω terminating resistor
between the CAN high and CAN low signals. This helps avoiding interferences on the bus.

13
3.3.Put down the serial number
Each PowerPlex®component has a unique serial number. Before mounting the PowerPlex®modules, we
recommend to prepare a list. This list should include: PowerPlex®component (module type), pertinent serial
number and installation area.
You find the serial number of the PowerPlex®Mini Module on the label attached to the housing. The serial number
consists of 7 letters and numbers. It is used as an identification for new, not yetprojected modules which have the
CAN bus address “0” for a start. The serial numbers are required for system set-up. By means of the PowerPlex®
configuration software the pertinent CAN bus addresses will be assigned.
Note
Please note the7-digit serial number of each PowerPlex®component. It isrequired for the subsequent
system configuration with the PowerPlex®configuration software.
Later, when you start configuring the modules and when you define their roles in the CAN network, the assignment
between serial number, CAN bus address and installation area must be made.
The use of CAN bus address labels helps keeping an overview for module identification, above all in the event of
comprehensive projects.
3.4.The CAN bus address
Any PowerPlex®component within a PowerPlex®network has its own, unique CAN bus address in a range of 1
to 30 for a clear identification. Assignment of the CAN bus addresses is during the system set-up by means of the
PowerPlex®Configuration Software (cf. PowerPlex®Manual Volume 3: System set-up and configuration).
We recommend to mark the modules in the PowerPlex®system with the corresponding CAN bus addresses so
as to be able to keep track.
4. General: PowerPlex®Mini Module MM500
Growing demands regarding safety and convenience lead to the installation of more and more electrical loads in
vehicles and boats. The PowerPlex®Mini Module (Fig. 6) is a multifunctional module that perfectly complements
the PowerPlex®product range. Like all the other PowerPlex®components it meets the special requirements of
marine and recreational vehicles applications.

Please ensure sufficient ventilation by leaving enough space at all sides of the device and ensure that
the vent holes are not blocked. Leave enough space between the devices.
Installation area
Ensure a tight installation on the mounting area. Please consider the vehicle-specific properties and
do not mount components in places where might affect the safety features of the vehicle. In addition,
make sure that the mounting surface is flat and even and not too rough so as to ensure the requested
protection degree.
Cable bushing
Ensure installation at a site where the cables can be laid and connected properly.
Electrical noise pulses
The installation site should provide sufficient distance to any devices that might emit noise pulses.
Table 7: General requirement of the installation site

18
5.3. General notes on wiring
The selection of the correct cable types is important for the reliable power distribution, control and monitoring by
means of a PowerPlex®system. Please ensure to use cables of superior quality with the suitable cross sections
to avoid voltage drops. Please also so the separate chapter 0 concerning the integration of the device into the
CAN bus network.
The cables should be laid very carefully to achieve the maximum performance of the PowerPlex®installation.
Table 8 gives general hints which must be observed regarding wiring of a PowerPlex®system and the connected
loads.
Item
Note
1
The cables should not be kinked or bent sharply. Please provide sufficient bending radii.
2
Cables mustbe protected against damages and heat. Avoid the proximity to moveable or hot parts and
to machines.
3
Cables should be secured by means of brackets or cable clips. Excessive cable lengths should be
disposed of appropriately.
4
Depending on the site of the cables, waterproof bushings might be useful.
5
Ensure a suitable strain relief.
6
Check cables about intact insulation, above all after cable laying.
Table 8: General notes on wiring
If AC and DC current is used for installation, an adequate insulation must be ensured.
Note
Please do not forget the 120 Ω terminating resistor when the PowerPlex®Mini Module is connected
as first and/or last participant on the CAN bus.
