1.2 Warnings and safety

1.2.1 Safety during installation and operation

Installing and operating the equipment may require work with dangerous currents and voltages. The installation must only be
carried out by authorised personnel who understand the risks involved in working with electrical equipment.

DANGER!
Hazardous live currents and voltages. Do not touch any terminals, especially the AC measurement inputs
and the relay terminals. Touching the terminals could lead to injury or death.

1.2.2 Metal fragments and other objects

Do not allow metal fragments or other objects to fall into the controller rack or display unit. Be especially careful during
installation, for example, when shortening wires.

To prevent metal fragments from falling into the controller rack, it is recommended to place a cover over the top ventilation
holes of the controller rack. The controller is supplied with a disposable cover to protect it from metal fragments and other
objects during the first installation.

CAUTION

Keep metal fragments out of the controller. Metal fragments can damage the controller.

CAUTION

Remember to remove the cover for the controller rack ventilation holes after work has been completed. Failure to do
so can damage the controller.

1.2.3 Electrostatic discharge

You must protect the equipment terminals from static discharge during handling, including installation and dismounting. Once
the equipment is correctly installed and the frame ground is connected, it is no longer necessary to protect the terminals from
static discharge.

1.2.4 Controller power supply

If the controller has no power supply, it is OFF and does not provide any protection to the system. The controller cannot
enforce any trip, block, or latch when it is off. All the controller relays de-energise.

The controller must have a reliable power supply, which must include a backup power supply. In addition, the switchboard
design must ensure that the system is sufficiently protected if the controller power supply fails.

1.2.5 Factory settings

The controller is delivered pre-programmed from the factory with a set of default settings. These settings are based on typical
values and may not be correct for your system. You must therefore check all parameters before using the controller.

1.2.6

Do not use unsupported hardware modules

CAUTION

Only use the hardware modules that are listed in the controller data sheet. Unsupported hardware modules can
make the controller malfunction.

3. Mounting the equipment

3.1 Introduction

3.1.1 Introduction to mounting the equipment

The controller rack should be delivered from the factory with all the required hardware modules. However, if you need to
mount an additional hardware module, or to replace a hardware module, read this chapter.

INFO

Hardware modules are standardised, replaceable printed circuit boards that are mounted in the rack. For example,
PSM3.1 is a hardware module that supplies power to the rest of the rack.

The controller rack is mounted in an enclosure, while the display unit is mounted in a panel.

This chapter describes how to mount or replace hardware modules, as well as mount the rack and display unit.

Deviating from the default configuration

You can mount the hardware modules in a different order from that recommended in these instructions. If you choose to do
this, DEIF recommends that you document where you have chosen to deviate from the default configuration and ensure that
this information is included in the system documentation. Record the following for each hardware module:

• Module name

• Module's rack slot number in the default configuration

• Module's rack slot number in your customised configuration

INFO

CAD drawings for both the controller rack and display unit can be download from the DEIF homepage. The
download is available as either an AutoCAD file or a stp file.

3.2 Mounting modules

3.2.1 Rack slots and their requirements

The following diagram shows the slot numbering in the rack. The power supply module (PSM) is always mounted in slot 1. If
a processor and communication module (PCM) is present, it is always mounted in slot 7.

1 432 5 6 7

The controller hardware modules can be arranged in any order in the rack, as long as they comply with these requirements:

• Apart from PSM and PCM, the hardware modules are slotted into the rack from slot 2 onwards, without leaving any empty
slots between the hardware modules.

• If a PCM is not present, slot 7 may be used for other hardware modules.

• "Blind" modules (these consist of the module faceplates only) must be installed over empty slots, to protect the controller
electronics.

INFO

If there are one or more empty slots between the hardware modules in the rack, the hardware modules after the
empty slot(s) cannot communicate with the PCM module. The software will not recognise or communicate with
these hardware modules either.

INFO

If you rearrange the order of the hardware modules, you may lose some/all of the module configuration information.
You should therefore always make a backup of the configuration before rearranging the hardware modules.

3.2.2

Mounting hardware modules in the rack

The controller will normally be supplied with the hardware modules already mounted. However, it may occasionally be
necessary for you to add or replace a hardware module. If you need to add a hardware module, you can use the first empty
slot from the left of the rack.

Legal

INFO

The manufacturer's warranty will not apply if the rack has been opened by unauthorised persons. However, you are
allowed to replace or add hardware modules (dedicated printed circuit boards) supplied by DEIF. To retain the
warranty, each hardware module must be mounted by a qualified person, in accordance with these written
instructions.

Safety: Hazardous live currents and voltages

DANGER!
Hazardous live currents and voltages may be present in a rack that is already installed. Contact with these
could kill you. Only authorised personnel, who understand the precautions needed and the risks involved
in working with live electrical equipment, may do this work.

Safety: Disrupting control

DANGER!
Working on the rack may disrupt the control of the generator, busbar or connection. Take the necessary
precautions.

Protecting equipment: No hot swapping

CAUTION

Disconnect all power supplies before removing or adding a hardware module. The hardware modules are not
designed for hot swapping.

Electrostatic precautions when mounting hardware modules

CAUTION

Protect the hardware modules against static discharge during installation. Protect the rack against static discharge if
it has not yet been mounted and the frame ground has not yet been connected.

Caution: No unsupported hardware modules

CAUTION

Only use the hardware modules that are listed in the controller data sheet. Unsupported hardware modules can
make the controller malfunction.

Physical mounting of hardware modules

1. Disconnect all power supplies (that is, the PSM and, if present, other modules with independent power supplies), to

protect the hardware modules and personnel.

2. Test the resistance of the wrist strap and the resistance of the wrist strap connection. Do not continue if the wrist strap

connection is faulty. Use the wrist strap at all times while installing or uninstalling the hardware modules to protect them
against static discharge.

3. If applicable, remove the hardware module to be replaced from the rack:

a. Remove the terminal blocks, and make sure that there are no wires in the way of removing the hardware module.

• Where relevant, disconnect the Ethernet cables from the top and bottom of the hardware module.

b. Loosen the hardware module faceplate screws using a screwdriver with a TX20 bit.

• Do not force the screws to unscrew completely. The screws are built-in and therefore normally remain attached to
the faceplate.

c. Use pliers or your fingers to pull the faceplate screws, and carefully slide the hardware module out of the rack.

• Only pull the screws. Do not pull any other part of the faceplate.

d. If you want to re-use the hardware module, or send it in for testing, be careful to only handle it by its faceplate. Put the

hardware module in ESD protective packaging after removing it.

4. To install the new hardware module:
a. Open the ESD protective packaging, and remove the new hardware module, holding it only by its faceplate.
b. Make sure that the hardware module is the right way up, and slide it into the correct slot. The hardware module

should slide in easily.

c. Tighten the screws on the hardware module faceplate using a screwdriver with a TX20 bit, and 0.5 N·m (4.4 lb-in) of

torque.

d. Replace all the terminal blocks, including any Ethernet cables to the module.

5. If the rack has not yet been mounted, return the rack to its protective packaging.

CAUTION

Dust accumulation may damage the controller or cause overheating. DEIF recommends mounting the rack in a
cabinet with a filter on the air supply.

CAUTION

Protect the controller terminals from static discharge during installation, especially while the frame ground is not
connected.

Cable requirements

Ensure that there is enough space in front of, above and below the rack for the cables.

INFO

DEIF recommends that you always follow the cable manufacturer's bend radius requirements. As a guideline,
Ethernet cables may require a minimum bend radius of around 40 mm (1.6 in). Load sharing and CAN bus cables
may require a minimum bend radius of around five times the cable diameter.

Ethernet cables

Allow enough space for the Ethernet cable plug and the Ethernet cable minimum bend radius. In addition, allow enough
working space above and below the rack to connect the Ethernet cables.

Fasteners for mounting the rack

Fasteners for mounting the rack are not supplied with the rack. The rack fasteners must be able to support the weight of the
rack and the wiring.

You can, for example, mount the rack using four Ø6 mm (1/4 in) bolts, four nuts and eight Ø6 mm (1/4 in) washers.

GPU 300 Installation instructions 4189341031 UK

www.deif.com

Page 18 of 76

Calculating minimum bolt length example

For bolts, the minimum length is 12 mm (0.47 in) for the rack mounting loop. Length is also needed for the washer
thickness (typically 1.5 mm), the nut (typically 4 mm) and the cabinet back plate thickness.

If the cabinet back plate is 2.5 mm (0.10 in) thick, then the minimum bolt length is 20 mm (0.79 in). For grounding, a
slightly longer bolt is required.

Mounting the rack

To mount the rack (using bolts, nuts and washers):

1. Check the rack orientation.

2. Check that the free space required for ventilation and cables is available.

3. Drill the holes required in the vertical surface on which the rack will be mounted. The rack must be mounted with its back

vertical, and its long axis horizontal. The writing on the modules must be horizontal.

4. Mount the four bolts on the vertical surface that the rack will be mounted on, and put a washer on each bolt.

5. Slide the rack onto the bolts, and put a washer on three of the bolts.

6. Screw the nuts onto the three bolts, and tighten them, using 5 N·m (44 lb-in) of torque.

7. Put a toothed lock washer on the remaining bolt, teeth facing the rack mounting loop. The washer must cut into the rack

mounting loop, to ensure there is a good galvanic connection.

8. Put one end of the grounding wire on the bolt.

9. Screw the nut onto the bolt, and tighten it, using 5 N·m (44 lb-in) of torque.

10. Galvanically connect the other end of the grounding wire to the cabinet.

Cable strain relief

You can use the cable strain relief plates mounted at the top and bottom of the front of the rack to hold cables in place.
Thread cable ties through the slots in the plates and secure cables to these.

The rack is delivered with cable strain relief plates already mounted.

• You can remove a cable strain relief plate by unscrewing the three 3 mm screws using TX 10 screwdriver.

• You can remount the cable strain relief plate using the three 3 mm TX 10 screws and 0.5 N·m (4.4 lb-in) of torque.

Cable tie slots

There are six cable tie slots at the top of the rack, and six cable tie slots at the bottom of the rack, as shown in the figures
below.
The maximum cable tie width that can be used in the slots is 2.5 mm (0.1 in).

The cable ties and cable routing must not block more than 20 % of the ventilation holes.

INFO

Before the cable tie slots at the top of the rack are used, the foil cover must be removed completely.

4. Default wiring for the controller

4.1 Introduction

4.1.1 Introduction to default wiring

The default terminal connections are shown using a *. Other connections that you might want to use are listed in the tables
for each unit. Note that these other connections are optional and/or configurable. Some of the default terminal connections
are also optional, configurable, or the function may be achieved using other terminals.

Wiring

The Wiring for the hardware modules chapter contains detailed information for each terminal of the hardware modules,
including examples of how these terminals can be connected to external hardware.

DANGER!
Only use the terminal blocks supplied by DEIF. Do not use substitutes.

CAUTION

Remove the foil cover placed over the top of the controller as close to the end of the installation as possible. Failing
to remove the foil cover before the controller is operational will damage the controller.

Specifications

The Data sheet contains the authoritative list of technical specifications for each set of terminals. For ease of use, some
simplified specifications are listed in this chapter.

Default configuration

This section also provides drawings of the default wiring for the relevant hardware modules for each unit. The drawing
symbols are included in the glossary. Drawings are not given for the hardware modules with no default wiring.

Custom configurations

You can connect the inputs and outputs to terminals other than the terminals specified in the default configuration. DEIF
recommends that you keep a record of where the wiring deviates from the default configuration.

In addition to the default wiring, the designer may specify inputs and outputs, according to the specific system's
requirements. These may use the available configurable connections in the basic unit's hardware, and/or the additional
connections made available by installing additional modules. These additional connections are not included in these default
wiring drawings, since they are specific to the system. These connections must be shown on the designer's drawings for the
system.

If there is space in the rack, you can mount additional modules for additional inputs and outputs. These inputs and outputs
are not described in these Installation instructions. The details of these connections are specific to the installation, and
must be included in the system designer's drawings.

Wire up the controller rack from right to left

DEIF recommends that you wire up the controller rack from right to left, because of the 45º terminal blocks.

**These two sets of voltage measurements must not be swapped around. The controller uses the second set of voltage
measurements together with the current measurements in a number of very important calculations.

GPU 300 Installation instructions 4189341031 UK

www.deif.com Page 31 of 76

DANGER!
The current measurement terminal block MUST always be screwed onto the module. Do not connect or
disconnect any current transformer (CT) while there is current in the line.

CAUTION

Only wire the neutral terminal if it is available on both the Busbar and Generator. If neutral is only wired on one side
of the equipment it causes a difference in the reference of a star connection. The difference causes an error during
synchronisation.

CAUTION

To prevent the voltage measurements from being swapped around, DEIF recommends that the voltage
measurement terminals are fitted with voltage encoding pins. Check that the wiring to the terminals has not been
swapped around during installation if voltage encoding pins are used.

4.4.2 Mounting voltage encoding pins

Voltage encoding pins are provided with the controller to prevent voltage terminal blocks from being mounted in incorrect
positions. Using the voltage encoding pins is not mandatory.

CAUTION

Swapping the voltage measurement terminals around can lead to dangerous situations. Check that the wiring to the
terminals has not been swapped around during installation if voltage encoding pins are used.

Optional installation equipment

Tool Function

Long nose pliers Improves the handling and placement of the voltage encoding pins.

Installing voltage encoding pins

Follow the procedure described below to install the voltage encoding pins.

INFO

For safety reasons the voltage encoding pins are not designed for reuse. Once they are installed it is difficult to
remove the pins without damaging the equipment. Ensure the voltage encoding pins are installed in the correct
positions the first time.

1. Identify the terminals where you want to place the encoding pins.
a. For example, terminal 1 in terminal group 1-2-3-4 and terminal 5 in terminal group 5-6-7-8 on the ACM3.1 module.

2. Remove the terminal blocks from the module.

3. Place the J-shaped encoding pin in one of the slots next to a terminal pin on the module. The encoding pin is secured
when you hear it click into position.
a. For example, next to the pin for terminal 1 on the ACM3.1 module.

4. Slide the flat encoding pin into the groove on the terminal block of second terminal group that matches the position of the
encoding pin placed in step 3.
a. For example, the groove at terminal 5 of the terminal block for terminal group 5-6-7-8 for the ACM3.1 module.

to the port. You therefore do not have to follow the list above. However, we recommend that you use the default connections
to simplify testing and troubleshooting.

See Wiring the controller hardware modules, Processor and communication module PCM3.1, Ethernet

connections for more information.

INFO

The Ethernet lines must not be longer than 100 metres, point-to-point.

5. Wiring for the hardware modules

5.1 Introduction

5.1.1 Introduction

This chapter describes the wiring for each of the controller hardware modules in detail. Each terminal's wiring is described,
with examples. However, wiring the system communication (including the connection to the display unit) is described in
another chapter.

The Data sheet contains all the technical specifications for all the terminals.

The default wiring is described in the chapter Default wiring for the unit.

DANGER!
You must only use the terminal blocks supplied with the controller and display unit. Do not use substitutes.

CAUTION

Only wire the neutral terminal if it is available on both the [Busbar] and [Controlled equipment]. If neutral is only
wired on one side of the equipment it causes a difference in the reference of a star connection. The difference
causes an error during synchronisation.

5.3.2

Voltage measurements wiring

See Default wiring for unit, ACM3.1 terminal connections and default wiring for more information about the
default wiring for voltage measurements.

DANGER!
DEIF recommends that you install fuses (2 A rating) on the voltage measurement lines, as close to the
busbar as possible. These fuses protect the voltage measurement lines.

5.3.3 Current measurements wiring

See Default wiring for unit, ACM3.1 teminal connections and default wiring for more information about the
default wiring for current measurements.

INFO

The current inputs are galvanically separated.

INFO

Mount each current transformer and connect it to the controller terminals so that each measurement current flows
through the controller in the correct direction. Incorrect mounting and wiring will result in incorrect current
measurements. See the controller wiring diagrams for the correct mounting direction and wiring.

DANGER!
Do not connect or disconnect any current transformer (CT) while there is current in the line. If a CT is
disconnected when there is current in the line, a high voltage is generated across the secondary of the CT.
This can cause arcing, personal injury or death, or damage to the controller.

DANGER!
The current measurement terminal block MUST always be screwed onto the module. If for some reason the
terminal block is unscrewed, secure it using a 0.5 N·m (4.4 lb-in) torque screwdriver with a 3.5 mm (0.14 in)
flat-bladed bit.

Relay output wiring

This relay has three terminals: normally closed, common and normally open (changeover relay). You can connect wiring to all
three terminals. Alternatively, you can connect wiring to only the common and normally open terminals, or only the common
and normally closed terminals.

For example, you can connect equipment to the normally closed terminal and the common. The following diagram shows an
example of a relay output where the normally open relay terminal is connected to an 230 V AC contactor. For this example,
the terminal connections can be swapped around without affecting the performance.

Similarly, you can connect equipment to the normally closed terminal and the common.

You can also connect equipment to both the normally open and the normally closed terminals, as shown in the following
diagram. For this configuration, current will flow through the equipment connected to the normally closed terminal when the
relay is de-energised. The current will flow through the equipment connected to the normally open terminal when the relay is
energised.

5.4.3

Digital inputs wiring

The digital inputs are bi-directional inputs. This means that wiring to the input and common terminals may be swapped
around without affecting their operation.

However, all the digital inputs on a module share a common terminal. The digital input common for a module may be either
low (connected to 0 V), or high (connected to 12 or 24 V). If the common is low, all the digital input signals connected to the
module must be high (connected to 12 or 24 V). Similarly, if the common is high, all the digital input signals connected to the
module must all be low (connected to 0 V).

The digital input common does not act as the common for any of the other terminals on the same module. The digital input
common is also not affected by the digital input commons on other modules.

The digital inputs are designed for a nominal voltage of 12 to 24 V DC.

7. Wiring the communication

7.1 DEIF Ethernet network communícation

7.1.1 Communication

An Ethernet network allows the controllers to communicate.

Table 7.1

DEIF network characteristics

Category Details

Specifications • Supports Internet Protocol version 6 (IPv6) and Internet Protocol version 4 (IPv4)

Functions

• Connects the controller(s) to:
◦ Controller display unit
◦ PICUS
◦ Modbus

• Password protection
◦ Customisable permission levels

7.1.2 Connecting the communication

Restrictions

• The Ethernet lines must not be longer than 100 metres, point-to-point.

• The Ethernet lines must meet or exceed the SF/UTP CAT5e specification.

CAUTION

The internal communication ports on the PSM must not to be used for the DEIF Ethernet network communication.
They are for future use for connecting extension racks together. Do not use either of the internal communication
ports in your communication setup. These are marked in red.

INFO

For marine applications, a marine-approved managed switch should be used to connect the DEIF network to your
own network. (An ordinary Ethernet switch is not recommended).

CAUTION

The switch must support Rapid Spanning Tree Protocol (RSTP) and RSTP must be enabled to prevent a broadcast
storm.

Ethernet port connections

The Ethernet ports on the controllers are not assigned to a particular service. The controllers detect the equipment connected
to the port. You can therefore use any port for any service.

However, the recommended default connection of the controllers is as follows:

Ethernet port protectors

The controllers are provided with two Ethernet port protectors that can be used as blanks for the Ethernet ports on the top of
the controller.

INFO

DEIF recommends that the Ethernet port protectors remain installed in the top Ethernet ports (connection 1 and 2)
when these are not in use. The Ethernet port protectors protects the ports from dust and foreign objects.

GPU 300 Installation instructions 4189341031 UK

www.deif.com

Page 62 of 76

Cable bend radius

Bends in the Ethernet cables must not be tighter than the minimum bend radius specified by the cable manufacturers.

INFO

DEIF recommends that you always follow the cable manufacturer's bend radius requirements. As a guideline,
Ethernet cables may require a minimum bend radius of 40 mm (1.6 in).

Redundancy and routing

Each controller can be connected so that there is redundant communication (that is, two independent Ethernet connections)
to other controllers. If you need redundant communication, you should route the Ethernet cables for redundancy. A single
failure (for example, damage to a cable rack) should not damage both of the Ethernet connections to the other controllers.

Wiring the Ethernet cable

The controllers and display units use any type of Ethernet cable, provided it meets or exceeds SF/UTP CAT5e specification.

CAUTION

Modifying Ethernet cables improperly may cause loss of network connectivity and EMC problems.

by using Modbus TCP/IP communication.

Alternating current AC

Alternating current
module 3.1

ACM3.1

A replaceable PCB with voltage and current measurement inputs. Used in the
DEIF controller.

Breaker

A mechanical switching device that closes to connect power sources to the
busbar, or to connect busbar sections. The breaker opens to disconnect the power
sources or to split the busbar.

Busbar

The copper conductors which connect the power sources to the power consumers.
Represented on the single-line diagram as the line that connects all the power
sources and power consumers. If the bus tie breaker is open, there are two
separate and independent busbar sections. Similarly, if the bus tie breaker is
closed, there is only one busbar.

Commissioning

The careful and systematic process that takes place after installation and before
the system is handed over to the operator. Commissioning must include checking
and adjusting the controller.

Common terminal COM

This is generally connected to either a power source, or the supply return. See the
wiring examples for more information.

Configuration

Assigning input and output functions to terminals, and setting parameters, so that
the controller is suitable for the application where it is installed.

Connected

A generator is connected to the system if it is running, synchronised with the
busbar, and its breaker is closed.

Controller GPU GPU 300, DEIF's Generator Protection Unit.

Current transformer CT

Digital input DI

Terminals on a controller hardware module that the controller uses to measure a
digital input. A pre-configured digital input function or alarm can be assigned to the
input.

Electrostatic discharge ESD

Generator breaker GB

The breaker between a genset and the busbar. The controller can control a
generator breaker.

Ground

A connection between the equipment and earth. For marine applications, a ground
is a connection to the ship's frame.

Hot swapping

NOT recommended. Changing hardware modules while the equipment is
powered, which may damage the equipment.

Input output module
