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(non-condensing).
• Verify installed environment meets this
  requirement.
• Refer to page three of installation manual.
• Refer to Red Warning Tag that is attached to
  disconnect

5
Startup

• 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.

6
Normal Status

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

7
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.

8
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.

9
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.

10
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.

11
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.

12
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.
