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.
