WARNING -
Hazardous Voltage & Shock Hazard
Failure to Follow These Instructions Could Result in Death or Serious Injury
• Only qualified licensed electricians should install or service SPDs
• Hazardous voltages exist within SPDs
• SPDs should never be installed or serviced when energized
• Use appropriate safety precautions including Personal Protection Equipment
• Failure to follow these instructions can result in death, serious injury, and/or equipment damage.
• This manual shall be read in entirety prior to installing
Bonding and Grounding Hazard
Verify that the neutral conductor in the service entrance equipment is bonded to ground in accordance with the National
Electrical Code (NEC®) and all applicable codes.
Verify that the neutral terminal (XO) on the secondary side of distribution transformers are grounded to the system ground
in accordance with the NEC® and all applicable codes.
During installation into an electrical system the SPD must not be energized until the electrical system is completely installed,
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 veried 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.
Introduction
Figure 1: SPD Types
Thank you for choosing the Siemens TPS3 09 Surge Protective Device
(SPD). TPS3 09 is a high quality, high energy surge suppressor designed
to protect sensitive equipment from damaging transient overvoltages.
The TPS3 09 is parallel connected such that circuit ampacity is
unlimited. Proper installation is important to maximize performance.
Please follow steps outlined herein. These instructions are not intended
to replace national or local codes. Follow all applicable electrical codes
to ensure compliance.
WARNING -

• Only qualified licensed electricians should install or service
SPDs
• SPDs should never be installed or serviced when energized
or during electrical storms
• Use appropriate safety precautions including Personal
Protection Equipment
• Failure to follow these instructions can result in death,
serious injury, and/or equipment damage
• When used in outdoor applications, customer must seal
the conduit nipple using watertight fittings (not included)
to ensure a watertight connection

Industry Standards Changes - 2009
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 I nominal testing (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 what you knew as SSA, 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 what you
know as hardwired SPD, and it may require external OCP.
Type 3 – Point of Utilization, direct plug in type devices, similar to what
you know as surge strips. Theses devices are intended for installation
10 meters from the panel (rational 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.
Hazardous Voltage & Shock Hazard
2008 NEC Art 285 & UL 1449-3
SPD Types: Types 1, 2, 3, & 4
Based on Location within electrical distribution system
(also coincides with ANSI/IEEE C62.41.2 - 2002 Categories C, B &A)
For further information, please review latest editions of NEC® Art. 285,
UL 1449, contact your local Siemens sales ofce or contact Siemens
TPS Tech Support at 1.888.333.3545.
The TPS3 09 is a Type 1 SPD. Type 1 SPDs are evaluated more rigorously
by UL 1449 for 2008 NEC® Article 285 compliance. Type 1 SPDs and
their connecting leads have been evaluated for line side applications
without need for supplemental overcurrent protection. Type 1 SPDs
include internal overcurrent protection. As a generalization, there are
practical maintenance reasons for installing on the load side of the main
overcurrent device (i.e. Type 2 installation). When connected on load
side of main disconnect, a 30A circuit breaker is recommended due to
10 AWG conductors. The circuit breaker serves as a disconnecting device
and provides NEC® imposed short circuit protection to the conductors
in Type 2 or 4 applications.
Simplified Explanation of Operation
SPDs sense overvoltage and create a momentary short circuit to redirect
harmful surge energy to earth ground. SPD’s are not a one time device.
They reset automatically and wait for the next surge. SPDs are capable
of repeating this function thousands of times.
