General Information

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 currrent for a very brief duration upon encountering a transient surge. The TPS3 unit contains overcurrent and thermal protection to protect against abnormal overvoltage conditions.

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 +60o C (+140o F) with relative humidity of 0%-95% (non-condensing).

Audible Noise

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 Instructions

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.
