FUNCTIONAL DESCRIPTION
The SPD150i is designed to protect single and three
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
main board protection and is connected in parallel
with the power system via HRC fuses.
This model ( SPD150i ) is designed for use in
systems with a grounded neutral in L-N mode. If
your system does not have a grounded Neutral or
is of a different voltage, this model is NOT
suitable.
OPERATION
Indicators - The operation status of the SPD150i is
indicated by leds on the front panel. The ‘OK’ ( blue )
light indicates that power is applied to the SPD150i
The ‘FAULT’ light ( red ) indicates that the surge
protection circuitry is damaged and the unit should be
replaced. The additional 3 leds ( blue ) indicate the
status of each MOV element. When the fault indicator
lights, the protection relay contacts change over. The
power failure alarm will operate when mains voltage
falls below 180VAC.

INSTALLATION
Refer to the following procedure to connect the
SPD150i.
1. CHECK
Always work safely-disconnect power before
making connections.
All wiring must be carried out by suitably
qualified personnel according to applicable
standards.
For installation adjacent to an M.E.N. link,
use the L-N mode. Insert insulated link as
shown.
For installation remote from the M.E.N. link,
use the L-E mode. Remove link. A separate
N-E protector may be required.
Always use correct size HRC fuses.
For services >125A use 125A HRC fuses.
For services <125A use 1 step below service
size. DO NOT USE AN MCB.
Always use Gg or Gl rated fuses. Do not use
delay types or semiconductor fuses.

2. INSTALL
Locate fuse position as close as possible to
the Main Switch.
Install fuse holders or fuse switch.
Locate suitable position for SPD ensuring
adequate space for cables. Do not install
above heat generating objects or any
position exposed to weather.

3. CONNECT
Connect wiring-refer to connection diagram
on this page. Always use bootlace wire
ferrules for lowest resistance to prevent
damage to wire.
Use suitably rated cable for power
connections. Cable should be rated for
operation at system voltage and be 4mm to
16mm sq.
Use shortest possible cables for all
connections or protection will be reduced.
For alarm cables use cable rated at system
voltage at between 0.5-1.5mm2.

3. NOTES
125A fuses are rated for maximum surge
rating.
Wiring from fuse to SPD carries surge
currents only. This means lower size cables
can be used than service size rating.
If using undersize cables we recommend
double insulating same.
It is recommended NOT to connect alarm
contacts to AC mains circuits if possible, to
prevent flashover from surges on AC line.
Connect to a BMS or PLC if possible.
Do not perform an insulation resistance test
on this unit as it contains voltage limiting
components which may be damaged during
testing.
3. EARTHING
The main earth wire (from earth link on
switchboard to ground rod or system ) MUST
be at least 6mm dia or larger.
Earth connections from the unit to neutral or
earth link MUST be as short as possible.
Failure to comply with the above points
can result in improper operation of the
unit and possible damage to the
installation.
