Visual Inspections
 Neutral and ground bond
needs to be visually
inspected.
 If bond is loose, missing, or
old, tighten, install, or
replace bond. Poor neutral to
ground bonds account for
99.9% of all surge protection
failures.
 Surge protection failure due
to poor neutral to ground
bond integrity will NOT be
warranted!
 Refer to page two of the
installation manual.

Verify Environmental Requirements
 This surge protector is
designed to operate indoors
in an ambient temperature
range of -40C (-40F) to
+60C (+140F) with a relative
humidity of 0% to 95%(noncondensing).
 Verify installed environment
meets this requirement.
 Refer to page three of
installation manual.
 Refer to Red Warning Tag
that is attached to disconnect

 Before energizing. Surge protection
must remain off until high-potential
insulation testing is finished. Refer
to page 1 of manual
 Once all installation procedures are
followed, surge protector can now be
energized.
 All Siemens TPS surge protectors
are designed to be virtually
maintenance free. Light indicators
show protection status. The
following slides show different light
conditions and what they mean.

Normal Status
Normal 100% function suppressor will have three green lights. The service light
will not illuminate nor will the audible alarm sound.

Testing Status
If the unit is in “Normal Mode – All green lights”, pressing the “Test” button will cause the red service
light to illuminate, the audible alarm to sound, and the dry contacts will change state. Also, the green
lights remain illuminated during the test. Once the “Test” button is released, the service light stops
illuminating, audible alarm will stop sounding, and the dry contacts will reset. The green phase lights
stay illuminated.

Fault Condition
If a fault condition occurs, the audible alarm will sound, the Red Service LED will
illuminate and the LED representing the affected phase/s will extinguish, indicating
that the unit needs service. Contact a qualified electrician or technician for
evaluation.

Silence Audible Alarm
If an inoperative condition were to occur, the built-in audible alarm will sound and
the red Service LED will illuminate. This indicates that the unit needs evaluation by a
qualified electrician or technician. Until a qualified person evaluates the unit, press
Alarm Silence to silence the alarm. (The LED above Alarm Silence illuminates when
the alarm is deactivated. Normal operation occurs with the Alarm Silence LED
extinguished.) The red Service LED will remain illuminated even though the Audible
Alarm has been silenced.

Abnormal N-G Voltage Indicators
This SPD include N-G voltage indicators. If the SPD detects excessive N-G
voltage, the Red Service LED will blink and the Audible Alarm will cycle. This
condition requires immediate attention as the SPD will fail.
Immediately TURN OFF the SPD, and contact electrician to inspect system
grounding.

What Causes Abnormal N-G Voltage?
Incorrectly bonded distribution systems damage SPDs. If the XO or N-G bonding
jumper is not installed, the electrical system has no reference to ground. It becomes
an ungrounded system. Please see previous section regarding SPDs on ungrounded
systems. Such systems are known to eventually produce abnormally high L-G
voltages.
SPDs will attempt to chase this system-level overvoltage abnormality until the SPD
fails. This effect is accelerated on Wye systems where SPDs are designed for
grounded systems. (SPDs for ungrounded systems generally have higher MCOV to
allow for L-G voltage fluctuations.) Failures of this nature are not defects in the SPDs
workmanship or material. This is an installation error and is not covered by warranty.
A differential voltage circuit monitors neutral to ground voltage. When N-G voltage
becomes excessive, an amplifier energizes a resistor. Eventually, that resistor will
overheat and cause thermally sensitive shrink wrap to shrink around the resistor. This
does not occur on transient or instantaneous N-G overvoltages. When the SPD is
deenergized, the shrink wrap covered resistor can be accessed by qualified
personnel under the display plate cover.

Return To Normal Status
Once damaged modules are replaced, the phase light or lights will return to their green state,
and the service light will stop illuminating. Also, the audible alarm will stop sounding. If the
audible alarm silence switch was depressed to turn off the alarm, the silence alarm light will
remain on. You need to depress the silence switch again to activate the audible alarm and turn of
the silence alarm light.
