SPC Max Series surge protective device

Operating features

General
The Eaton SPD Max Series comes in three feature packages: basic,
standard with surge counter, and Power Xpert SPD . The operating
specifics of each feature package are described below .
The Eaton SPD Max Series requires no operator involvement other
than to monitor the display panel or the audible alarm (if equipped)
to determine status of the SPD(s) .
After system power is applied, the SPD automatically begins
protecting downstream electrical equipment from voltage
transients and surges .
Some SPD Max Series units have a Form C relay contact that allows
for the remote indication of SPD status . Wiring of the Form C
contacts is not mandatory for the operation of the SPD Max
Series device.
Displays and indicators
All Eaton SPD Max Series units (basic, standard with surge counter,
and Power Xpert SPD) use a display panel to indicate system status .
The display panel is slightly different for each feature package .
Each display has both green and red light-emitting diodes (LEDs) to
indicate the protection status on each phase:
•
Green indicates the phase is fully protected
•
Red indicates a loss of protection
•
Wye, split-phase and high-leg delta units have an additional set of
green/red LEDs to indicate status of neutral/ground protection
The Power Xpert SPD has LEDs that can be green, yellow, or red
depending on the protection level of the SPD .
•
Green LEDs indicate the phase is fully protected
•
Yellow LEDs indicate a partial loss of protection
•
Red LEDs indicate a total loss of protection and the SPD should
be replaced
When an LED turns red, an audible alarm will also sound on units
equipped with an audible alarm .
Descriptions of the specific operating conditions displayed for each
Eaton SPD Max Series feature package are as follows .
