inspected and tested. All conductors must be connected and functional including the neutral (if required). The voltage
rating of the SPD and system must be verified before energizing the SPD.

Failure to follow these guidelines can lead to abnormally high voltages at the SPD. This may cause the SPD to fail. The
warranty is voided if the SPD is incorrectly installed and/or if the neutral conductor in the service entrance equipment or
downstream of separately derived systems is not bonded to ground in accordance with the NEC®.

Do Not Hi-Pot Test SPDs

Any factory or on-site testing of power distribution equipment that exceeds normal operating voltage such as
high-potential insulation testing, or any other tests where the suppression components will be subjected to higher voltage
than their rated Maximum Continuous Operating Voltage (MCOV) must be conducted with the SPD disconnected from the
power source. For 4-wire systems, the neutral connection at the SPD must also be disconnected prior to performing high­potential testing and then reconnected after test completion.

Failure to disconnect SPD and associated components during elevated voltage testing will damage the SPD and will void
the warranty.

Industry Standards Changes - 2009

Siemens TPS3 SPDs have the following Type designations

UL 1449 Third Edition and 2008 NEC® Article 285 generated substantial
changes.

• The term TVSS changed to SPD

• Types 1, 2, 3 & 4 SPDs are created

• UL 1449 clamping voltage performance testing changed from
500A to 3,000A

• UL 1449 added new Nominal Discharge Current testing (I nominal,
or In), which consists of more rigorous duty-cycle testing

The SPD Type category is important to understand before installing
any SPD. Type 1 and 2 SPDs are fully UL Listed devices whereas Type
4 SPDs are UL Recognized devices.

Type 1 – Installed on line or load side of the Main Overcurrent Protection
(OCP), similar to obsolete products known as Secondary Surge Arrestors,
except now includes rigorous safety testing. Includes all OCP & safety
disconnectors inside the SPD.
Type 2 – Installed on load side of the Main OCP, similar to previous
products known as TVSS. May or may not require external OCP.
Type 3 – Point of Utilization, direct plug in type devices, surge strips,
etc. Theses devices are intended for installation 10 meters from the
panel (rationale based on IEEE Cat. A location).
Type 4 – Surge suppression components, could be a basic component
or a complete module. Type 4 components can be tested for Type 1,
Type 2 or Type 3 applications.

Equipment Performance

As SPDs sense overvoltage, they create a momentary internal short
circuit, thereby redirecting harmful surge energy to earth ground.
SPDs are capable of repeating this function repeatedly. For optimum
protection, staged surge suppression should be implemented at the
service entrance and all other distribution or panelboard locations
feeding sensitive equipment.

Voltage Rating

Prior to installing the TPS3 SPD, verify that the unit has the correct
voltage rating for the equipment installed by checking the nameplates
of both the equipment and TPS3 module. The service type should
match the intended power source. See Table 2 on the following page
for voltage applications.

General Information

Audible Noise

This device features internal overcurrent and overtemperature
protection that will disconnect affected surge suppression components
at the end of their useful life, but will maintain power to the load – now
unprotected. If this situation is undesirable for the application, follow
these instructions for servicing or replacing the device.

Service of this unit consists of replacing the internal module and/or
display assembly.

There are no user-serviceable parts inside the replaceable module. Do
not attempt to disassemble the module as it stores charge.

Precautionary Statement Regarding SPDs on Ungrounded Systems

Caution – Ungrounded systems are inherently unstable and can

product excessively high line-to-ground voltages during certain fault
conditions. During these fault conditions, any electrical equipment
including an SPD, may be subjected to voltages which exceed their
designed ratings. This information is being provided to the user so
that an informed decision can be made before installing any electrical
equipment on an ungrounded power system.

Overcurrent Protection

The TPS3 SPD unit draws very little current under normal operation and
will only conduct current for a very brief duration upon encountering
a transient surge. The TPS3 unit contains overcurrent and thermal
protection to protect against abnormal overvoltage conditions.

The SPD’s background noise is negligible which permits installation
within the equipment in almost any room.

Dead Front Modification Instruction Changes for P1 SPD

The TPS3 unit requires a dead front opening to display its face
plate. Remove any installed cover from a dead front opening at the
TPS3 module location. If there is no dead front opening, follow the
instructions in Fig. 2 to create an opening by removing a knockout plate.

P1 Dead Front Knockout Plate Removal Instructions

Stand the removed dead front on the floor with the plate to be removed
in the upper position, as shown below. Grasping the upper edge of
the dead front, press the cover plate out of the cutout.

Figure 2: Dead Front Modification Instruction

System Grounding

An equipment grounding conductor must be used on all electrical
circuits connected to the SPD.

For the best performance, use a single point ground system where
the service entrance grounding electrode system is connected to and
bonded to building steel, metallic piping, driven rods, etc. (NEC® and
IEEE Std 142-2007 are appropriate standards).

For sensitive electronics and computer systems, ground impedance
should be as low as possible. When metallic raceway is used as an
additional grounding conductor, an insulated grounding conductor
should be run inside the raceway and sized per the NEC®. Adequate
electrical continuity must be maintained at all raceway connections.
Do not use isolating bushings to interrupt a metallic raceway run.

A separate isolated ground for the SPD is NOT recommended because
it may isolate the SPD from the rest of the electrical system, thus
decreasing performance. Proper equipment connections to grounding
system and ground grid continuity should be verified via inspections
and tested on a regular basis as part of a comprehensive electrical
maintenance program.

On 4-Wire Power Systems, neutral to ground bonding (Main Bonding
Jumper) must be installed per the NEC®. Failure to do so WILL damage
SPDs.

Environment

The unit is designed to operate inside the equipment in a room ambient
temperature range of: -40ºC (-40ºF) to +60ºC (+140º F) with relative
humidity of 0%-95% (non-condensing).

TPS3 01 Installation Instructions for: Lighting Panelboards Original P1, P2, P3

If model number includes W option suffix, additional instructions
follow:

The following instructions are for the installation of the Siemens TPS3
01 and L1 SPD modules in Siemens Original P1, P2 and P3 lighting
panelboards. Be aware of differences between the Revised P1 and
Original P1 panelboards. SPDs for Original P1 and Revised P1 are not
interchangeable. Original P1 panelboards use TPS3 01 or L1 SPDs,
whereas Revised P1 panelboards use TPS3 02 or L2 SPDs.

To determine if a customer has a Revised P1 panel – look at the part
number of the interior. If the part number ends with “N” or “T” then
it is a Revised P1. If it does not end in either “N” or “T” then it is an
Original P1 panel. For example: P1E42MC250A is an Original P1 panel
and P1E42MC250AT is a Revised P1 panel. If it is a Revised P1 panel
ending in “N” – then there is no Subfeed space and no place for an
SPD to be installed internally.

TPS3 01 and TPS3 06 Module Installation
Instructions: MCC

Figure 8: Installation

in an MCC

The following instructions are for the replacement of Siemens TPS3
SPD module in a TIASTAR MCC.

This unit is intended for custom factory installation during MCC
manufacture. Unit must be removed from the MCC or withdrawn
to the TEST position. Familiarize with the TPS and MCC mounting
hardware-mount in gear such that the leads are as short and straight
as possible without distorting the stab assembly. Failure to do so will
result in decreased performance.

Diagnostic Display Connected via Ribbon Cable – to be mounted in a
suitable location such that the display is visible to user and/or protected
via an access door.

A successful installation includes:

• Meets all national and local codes.

• Mount TPS as close as possible to electrical connection.

• Ensure leads are as short and straight as possible.

• Gently twist or tie-wrap conductors together wherever possible.

• Ensure that N-G bonding hazard warning label is attached to TPS
as reminder to installing contractor.

• Ensure all power is off and unit is deenergized.

• Verify that TPS and intended voltage are correct.

• Install #6 conductor leads to phase, neutral and ground connections.

• Mount Diagnostic Display at appropriate location.

• Connect ribbon cables from Diagnostic Display to circuit board on
Main TPS Backplane Assembly.

• Connect to the Dry Contact terminal block if appropriate.

Before bench testing

• Ensure test voltage is appropriate and grounded Wye system
– Failure to ensure reference to ground will fail unit.

• Ensure unit is touch safe and that all appropriate enclosures are secure.

• Do not Hi-Pot test SPDs.

• Do not bench test using ungrounded system – must be grounded

Wye system.

UL 1283 required language concerning the installation of EMI Filters

a) An insulated grounding conductor that is identical in size and
insulation material and thickness to the grounded and ungrounded
circuit supply conductors, except that it is green with or without
one or more yellow stripes, is to be installed as part of the circuit
that supplies the filter. Reference should be made to Table 250-122
of the National Electrical Code regarding the appropriate size of the
grounding conductor.

b) The grounding conductor mentioned in item a is to be grounded
to earth at the service equipment or other acceptable building earth
ground such as the building frame in the case of a high-rise steel­frame structure.

c) Any attachment-plug receptacles in the vicinity of the filter are to
be of a grounding type, and the grounding conductors serving these
receptacles are to be connected to earth ground at the service equipment
or other acceptable building earth ground such as the building frame
in the case of a high-rise steel-frame structure.

d) Pressure terminal or pressure splicing connectors and soldering lugs
used in the installation of the filter shall be identified as being suitable
for the material of the conductors. Conductors of dissimilar metals shall
not be intermixed in a terminal or splicing connector where physical
contact occurs between dissimilar conductors unless the device is
identified for the purpose and conditions of use.
Additional instructions for TPS3 01 & L1, 02 & L2 SPDs including:

W Option Suffix:

The W option includes repositioned phase connection tabs that allow
for wire connections to a circuit breaker within the panelboard. This
differs from non-W models, which bolts directly to bus bars.

The circuit breaker serves as a disconnector device and overcurrent
protection to the connecting conductors. The TPS3 SPD includes internal
overcurrent and overtemperature protective equipment. The breaker
does not provide overcurrent protection to the SPD.

Recommended breaker and conductor size is 60A with a 6 AWG
conductors. Other combinations are possible. Terminal lugs will accept
2-14 AWG. Breaker size should be at least 20A. All applicable codes
must be followed.

Circuit breaker MUST be located immediately adjacent to SPD to minimize
lead lengths. Move or adjust breaker positions as appropriate. Every
effort must be taken to reduce lead lengths. Failure to install short
leads will degrade SPD performance.

Install appropriate circuit breaker in panelboard.

Confirm that all LEDs are green and that touchpads on display operate
correctly.

10

Prior to installing SPD, install, rotate and tighten box lug terminals to the
top of the SPD phase connection tabs, pointing toward breaker location.

Mount the SPD using supplied hardware, per previous instructions.
Connect the neutral connection by wire or bracket as appropriate.
Install conductors: Identify each panelboard buss as Phase A, B and C.
When the SPD is installed, the SPD’s Phase Tabs will have near proximity
above energized panelboard busses. The SPD’s phase connections must
correspond to buss phases. Connect conductors from the SPD’s Phase
Tabs to corresponding circuit breaker connections. For example, when
energized, the SPD Phase Tab for Phase A must be located above the
panelboard buss for Phase A. The SPD Phase Tab for Phase B must be
located above the panelboard buss for Phase B. The SPD Phase Tab
for Phase C must be located above the panelboard buss for Phase C.

Conductors must be as short and straight as possible. Use gentle radius
on any bends. Do not kink wires. Prevent wires from encroaching
breaker locations.

Torque all connections to the values specified on the installation and
maintenance instruction label affixed to the rear of the dead front.

Replace dead front supports and trim.

Energize breaker and confirm proper SPD operation.

Test: Tests red Service LED and Audible Alarm, and changes state of
Dry Contacts.
Alarm Silence: Turns Audible Alarm off. (Alarm is deactivated when
the Silence LED is illuminated.)

Surge Counter Count: (if equipped) Increments optional surge counter
by one (+1).

Surge Counter Reset: (if equipped) Resets optional surge counter to
zero (0).

Operation

TPS3 surge protective devices require minimal attention after installation.
TPS3’s contain diagnostic circuits which monitor the suppressor's status
continuously and automatically. All phase indicators and controls are
located on the display panel of the unit. Display panels are formatted
either for horizontal or for vertical mounting orientation as required
for each application.

TPS3 Control & Diagnostic Display Panel

TPS3’s are equipped with a status indicating LED for each phase on
the panel. When all LED's are green, the suppressor is on-line and
functioning properly. If a fault condition occurs, the audible alarm will
sound, the Red Service LED will illuminate and the LED representing the
affected phase will extinguish, indicating that the unit needs service.
The audible alarm can be silenced by pressing ALARM SILENCE on
the touchpad. The audible alarm and Dry Contact can be tested by
depressing TEST. If a fault alarm occurs, see Corrective Maintenance
(Testing and Repair) for further information.

Display Panel with Surge Counter Option

The surge counter option provides a means to display the total number
of transient voltage surge events since the counter was last reset. The
counter includes Eprom memory, which retains counter memory in
the event of a power loss. The RESET touchpad will reset the counter
to zero. The COUNT touchpad increments the counter by one (1) and
tests the circuitry for proper operation. If a fault alarm does occur, see
Corrective Maintenance (Testing and Repair) for further information.

Dry Contacts Feature

TPS3 01, 05, and 06 units are equipped with dry contacts. This feature
provides Normally Open (N.O.) and Normally Closed (N.C.) circuits,
which can be used for remote indication of a failed transient voltage
surge suppressor. There is only one dry contact output consisting of
two electrically isolated sets of NC-C-NO contacts. This dry contact
output changes from "normal" to "alarm" if any problem occurs inside
the SPD (i.e.: loss of power to any phase, any thermal protector inside
the SPD opens, or any fuse inside the SPD opens). The dry contact
terminal block is located on the back of the module, opposite side of
bus tabs. This connector is designed for low voltage or control signals
only. Maximum voltage should not exceed 240 volts and maximum
current should not exceed 5 amperes. These contacts may be used to
provide a signal to an emergency management system or computer
interface board. The relay contact pin arrangement is outlined in the
table below.

The Normally Closed (N.C.) configuration is recommended because
it will detect a wiring defect, such as a cut wire(s), where Normally
Open (N.O.) will not.

Maintenance

Module Replacement & Service

SPDs require minimal maintenance. Periodic inspection of diagnostic
LED indicators ensures proper operation. Clean SPD as appropriate.

Troubleshooting & Service

Please contact TPS Technical Support at 1.888.333.3545 for service
related issues.

Quality SPDs are designed and tested to withstand severe duty. However,
there are various electrical anomalies against which SPDs cannot protect.
These are generally Sustained Overvoltages also known as Temporary
Overvoltages (TOVs). In this context, Sustained Overvoltages may be
only a few cycles. Failed SPDs tend to be symptoms, not root causes.
There may be larger issues at play. Regardless of cause, SPDs attempt
to protect their load until failure.

Bonding or reference to ground problems are the root cause of many
SPD problems. If the SPD shows problems on startup, there is reasonable
chance of bonding/grounding/misapplication issue. Such problems
permanently damage the SPD. If not corrected, SPD problems will
reoccur.

Tip: Visually confirm N-G bonding. Be aware that a voltmeter
measuring N-G can be misleading. For example, N-G voltage
could read 0V because neutral and ground are at the same
potential purely by happenstance, not because they are
bonded. Visually confirm bonding.

The module is field replaceable. Service should only be performed
by qualified persons. Deenergize SPD, confirm with appropriate
measurement equipment and discharge internal capacitance to ground.
Mark locations and carefully disconnect diagnostic cables, contacts,
connecting conductors, etc. Unbolt module from backplane. Reinstall
in reverse.

There are no user serviceable parts inside the module. Disassembly
is not permitted.

Modules may be returned to the factory for factory service, qualification
and return. Please contact factory at 1.888.333.3545 for assistance.

Display Replacement

The display is field replaceable. Service should only be performed
by qualified persons. Deenergize SPD, confirm with appropriate
measurement equipment and discharge internal capacitance to ground.
Mark locations and carefully disconnect diagnostic cables, contacts,
connecting conductors, etc. Unbolt display and replace. Reinstall in
reverse.

Note that a sealing gasket between the display and the enclosure is
a key component ensuring weather resistance. Replace the gasket
whenever the display is removed.

Preventive Maintenance (Inspection & Testing)

Tip: Experience indicates that regulation-challenged
generators can cause Sustained Overvoltages, as well as
ungrounded generators, and/or usual load transfer systems.

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.
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.

Inspection of the TPS3 SPD unit should be performed periodically,
to maintain reliable system performance and continued transient
voltage surge protection. The large variations in operating conditions
encountered by units in the field make it difficult to set a fixed
maintenance interval, but inspections utilizing the built-in diagnostics
should be performed at least on a weekly or monthly basis.

Corrective Maintenance (Repair)

The Siemens TPS3 unit is designed for years of reliable, trouble-free
operation. Unfortunately, in an extreme case, you may experience an
alarm condition. In this event, no attempt should be made to repair the
TPS3 itself. There are no serviceable parts within the unit. Any SPD that
requires service should be appropriately removed from the electrical
distribution equipment, and replaced by a new SPD of the same model.
