Siemens Surge Protective Device TPS3 09 - Manual (Page 4)

Carefully inspect each item in the package for signs of damage. If
damage is found, please contact Siemens TPS Technical Support:
1.888.333.3545. For more information about this product or other

Figure 2: Dimensions and Weight
TPS3 03’s have demonstrated 200kA Short Circuit Current Ratings
(SCCR) including leads (120/240V Split phase models have 100kA
SCCRs). See UL Label markings on SPD or see Data Sheet for specs for
verification. Supplemental overcurrent protection is not required to
protect this SPD. However, NEC® convention requires that connecting
conductors have overcurrent protection in Type 2 or 4 applications.
Follow applicable codes.
This device features internal overcurrent and overtemperature
protection that will disconnect effected 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.

SPDs on Ungrounded Systems
Caution – Ungrounded systems are inherently unstable and can
produce 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.
