FUNCTIONAL DESCRIPTION
The SPD3i is designed to protect 3-phase power
systems against damage from surges and spikes
caused by lightning and other electrical sources. The
unit is intended for point-of-entry or sub-board
protection and is connected in parallel with the power
system via HRC fuses. This unit is available in
various models for different voltages and
applications. Check that the model you have
purchased is rated correctly for your power system.
.
This model (SPD3Gi/A) is designed for TN-S and
TT power systems in the range of 220-300V(380-
520V). If your power system is TN-C, TNC-S or IT,
or of a different voltage, this model is NOT
suitable.
Please contact your supplier for a suitable model to
suit your application.
OPERATION
Two lamps on the front panel indicate the operation
status of the unit. The ‘OK’ lamp indicates that power
is applied to the unit and the ‘FAULT’ lamp indicates
reduced protection. If the ‘FAULT’ lamp is lit it is likely
that the unit is damaged and must be replaced. If the
breaker/fuse is intact and power is definitely being
supplied through the unit (check with meter) but the
‘OK’ lamp doesn’t light then the unit is faulty and
must be replaced.
WARRANTY
Eaton Power Quality warrants this unit against faulty
parts and workmanship for a period of 12 months
from the date of purchase. If this product fails to
operate correctly, please contact your Eaton
representative. This warranty doesn’t cover neglect
or intentional misuse. As this product is intended for
use in electrically harsh environments no claim is
made of suitability for purpose. This unit is designed
to reduce the likelihood of damage, not prevent it.
Please also note that an excessive surge, such as
from a direct lightning strike to the site or a power
system fault, may cause damage to the unit and
render it inoperable. A unit that has been damaged in
this way is not warrantable.

WARNING – OBSERVE THE SUPPLY VOLTAGE LIMITATIONS
OF THIS UNIT. FAILURE TO OBSERVE THIS WARNING WILL
RESULT IN DAMAGE TO THE UNIT. DAMAGE FROM
EXCESSIVE SUPPLY VOLTAGE IS NOT WARRANTABLE.
INSTALLATION
Refer to the procedure and diagram shown to connect the
SPD3Gi/A.
PROCEDURE:
1. CHECK
• Always work safely – disconnect power before making
connections.
• All wiring must be carried out by suitably qualified
personnel according to the applicable standards.
• Check for correct operating voltage and power system.
This model (SPD3Gi/A) is designed for TN-S and TT
power systems in the range of 220-300V(380-520V). If
your power system is TN-C, TNC-S or IT, or of a
different voltage, this model is not suitable. Please
contact your supplier for a suitable model to suit your
application.
• Always use the correct size HRC fuses.
• For services >125A, use 125A fuses. For services
<125A, use one step below service fuses (i.e. 80A
service = 63A fuses). DO NOT USE A 3-PHASE MCB.
• Always use Gg or Gl-rated fuses. Do not use delay types
or ‘semiconductor’ fuses.
• Consider fitting a fuse-switch or a separate isolation
switch to facilitate safe maintenance in the future.
2. INSTALL
• Locate a fuse position as close as possible to the Main
Switch.
• Install fuseholders or fuse-switch.
• Locate a suitable position for the SPD3, ensuring
adequate space for cables. Do not install above heat-
generating objects or in any position that is exposed to
weather.
• Install unit to DIN-rail in switchboard or cabinet.
3. CONNECT
• Connect wiring - refer to connection diagram. If using
stranded cable, always use wire ferrules for lowest
resistance and to prevent damage to the wire.
• Use a suitably-rated cable for power connections. Cable
should be rated for operation at the system voltage and
should be 4mm2to 16mm2.
• Use short cables for phase, neutral and earth
connections or protection will be reduced.
• Use a suitably-rated cable for alarm connections. Cable
should be rated for operation at the system voltage and
should be 0.5mm2to 1.5mm2.
4. NOTES:
• 125A fuses are rated such for maximum surge rating.
On services below 150A, use the correspondingly lower
sized fuse (i.e. 80A service = 63A fuse).
• Wiring from fuse to SPD is carrying surge currents only,
not load current. This means that smaller cables may be
used than is normal for the current rating.
• If using under-sized cables, some energy authorities
require double insulation (i.e. sleeving) of the cables.
• Maximum alarm relay resistive load is 5A.
• It is recommended not to connect the alarm contacts to
AC mains circuits if possible, to prevent flashover from
surges on the AC line. Connect to a PLC or BMS if
available.
• Do not Megger test cabling with unit connected – unit
may be damaged.
EARTHING
For proper operation, all surge diverters rely upon a good earth
connection. In some installations the existing earth system may
require upgrading. Important things to look for are:
• The main earth wire (from earth link on switchboard to ground
rod or system) MUST be at least 6mm diameter (preferably
larger) and should be as short as possible.
• Earth connections from the unit to earth link MUST be as short
as possible.
Failure to consider the above points can result in improper
operation of the unit and possible damage to the installation.
If you experience any problems with the
installation or commissioning, contact your
Eaton representative for guidance.
