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.
