DANGER

HAZARDOUS VOLTAGE

Disconnect all power supplying this equipment before replacing.

Failure to do so will result in death or serious injury.

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.
