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.

Page 12 of 76

PSM PCM

56
3 42
17
56
3 42
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.
GPU 300 Installation instructions 4189341031 UK

Page 14 of 76

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.

For UL/cUL listing, the rack must be mounted on a flat surface of a type 1 enclosure. For UL/cUL listing, the rack must be
installed in accordance with the NEC (US) or the CEC (Canada). See the Data sheet for more details.

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.

Ventilation requirements
For ventilation, there must be a minimum of 20 mm (0.8 in) free space above and below the rack frame.
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.

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.

3.3.4 Rack cable strain relief
Use the cable strain relief plates or the cable tie slots to secure cables and wiring.
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.
