Parts List and Inspection
Items included in the package consist of the following:
•
1 TPS3 09 SPD including 3' (1~m) conductors
•
1 User's Manual (this document)
*See figure 4 for installation
If the Flush Mount Kit was ordered, additional parts are supplied
as follows:
•
1 Flush Mount Plate
•
4 Mounting Screws
TPS3 09 has demonstrated 200kA or 100kA Short Circuit Current
Ratings (SCCR) including leads. See UL Label markings on SPD or
see Data Sheet for specs.) Supplemental overcurrent protection
is not required to protect this SPD. However, NEC® and CEC
convention requires that connecting conductors have overcurrent
protection in Type 2 applications. Follow applicable codes.
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 replacing the
device. TPS3 09 is ultrasonically welded closed and contains no
user serviceable parts.

Voltage Rating & Application
Before installing SPD, verify the nameplate voltage has the same
voltage rating as the power distribution system. If unsure, call
Siemens TPS Tech Support at 1.888.333.3545 before proceeding.
The SPDs specifier or user should be familiar with the configuration
and arrangement of the power distribution system. The system
is defined by how the secondary windings of the transformer
supplying the service entrance main or load are configured. This
includes whether or not the transformer windings are referenced
to earth via a grounding conductor. The system configuration is
not based on how any specific load or equipment is connected to
a particular power distribution system. SPDs should be installed
per the distribution system, not per a load or motor's wiring
connection.
For example, suppose a 480V three phase motor appears to be
connected as a 480V Delta. In actuality, the serving distribution
system might be a 480Y/277V grounded Wye, with or without a
neutral pulled to the motor or MCC. The system is still a 480Y/277V
Wye, even though the load is connected as a Delta. A grounded
Wye has a defined reference to ground (i.e., neutral is bonded to
ground). In contrast, some Delta systems are ungrounded, which
have no reference to ground.

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.
