INSTALLATION INSTRUCTIONS:
Pro-Stock Panelboards with
TRANQUELL Medium Exposure Transient Voltage Surge Suppressor
IMPORTANT NOTICE
THE ENTIRE CONTENT OF THIS MANUAL MUST BE READ AND FULLY UNDERSTOOD BEFORE ATTEMPTING ANY INSTALLATION OF THE TRANQUELL SERIES TVSS.
If there are any questions about the operational status, or integrity of the electrical system prior to installation of the TVSS, please consult a qualified trained electrician before attempting to continue.
If the minimum requirements of this manual are not followed, the TVSS could become irreversibly damaged, and/or the electrical system could be left unprotected.
Choosing the right product for the application, along with correct installation methods, as defined within this manual, will allow the Tranquell TVSS to provide the best possible protection for many years.
Failure to comply with the applicable requirements of this manual can void the TVSS warranty.
SPECIAL ATTENTION MUST BE GIVEN TO VERIFY THAT A PROPER NEUTRAL-GROUND (XO) BOND HAS BEEN MADE WHEN POWER IS SUPPLIED FROM AN UPSTREAM TRANSFORMER OR ANY OTHER TYPE OF SEPARATELY DERIVED POWER SOURCE.
FAILURE TO PROVIDE THIS BOND, AS REQUIRED PER ARTICLE 250.30 OF THE NATIONAL ELECTRICAL CODE, CAN RESULT IN ELEVATED PHASE TO GROUND SOURCE VOLTAGE POTENTIALS. THESE VOLTAGES CAN CAUSE DAMAGE TO ELECTRICAL EQUIPMENT AS WELL AS SAFETY HAZARDS INCLUDING FIRE, ELECTRICAL SHOCK, SERIOUS INJURY, OR DEATH.

Installation Instructions
Pro-Stock Panelboards with TRANQUELL Medium Exposure TVSS
THE EQUIPMENT COVERED BY THESE INSTRUCTIONS SHOULD BE INSTALLED AND SERVICED ONLY BY COMPETENT PERSONNEL UTILIZING PROPER SAFETY PRACTICES AND PROCEDURES.
THESE INSTRUCTIONS ARE WRITTEN FOR SUCH PERSONNEL AND ARE NOT INTENDED AS A SUBSTITUTE FOR ADEQUATE TRAINING AND EXPERIENCE IN SAFE PROCEDURES FOR THIS TYPE OF EQUIPMENT.
PRODUCT DESCRIPTION:
GE TRANQUELL TVSS models are Transient Voltage Surge Suppressors (TVSS), which provide metal oxide varistor protection in each mode, combined with thermal fuses, surge-rated fuses, indicating lights, an audible alarm with test and disable features, Form C contacts for remote monitoring, surge counter, built in EMI filtering. The units described in this manual are intended solely for installations in GE Pro-Stock Panels installed on low voltage electrical distribution systems. The TVSS is UL and cUL Listed E108159, conforming to UL standards 1283 and 1449 Second Edition, August 15, 1996. All ratings are in accordance with ANSI / IEEE C62.41-1991 and NEMA LS1-1992 recommended practices.
APPLICATION GUIDELINES:
Determining the surge protection to be provided in a facility or for a particular system or equipment can be a complex problem which should be addressed as early as possible, such as when a facility is constructed or sensitive equipment is installed. The following guidelines are offered for application assistance.
1. Ensure that your facility electric supply
system is properly installed and connected in accordance with all applicable national and local codes and safety procedures. All equipment and systems should be installed in accordance with manufacturer’s instructions.
2.Utilize the personnel from your local utility, your engineering department, GE application or service engineering, or a competent consulting engineering firm for technical guidance or troubleshooting.
3.Understand your system, and the capabilities and limitations of surge protectors and other power conditioning equipment.
4.Select the proper TRANQUELL Medium or High Exposure Series unit for your system voltage, configuration, and the anticipated surge environment.
MCOV (Maximum Continuous Operating Voltage)
This value defines the maximum line-to- line or line-to-neutral continuous voltage to be applied to the protector. MCOV values for Tranquell Series TVSS are set at 115% of nominal system voltage. For 120-volt systems, the MCOV is 125%. If sustained voltage could exceed MCOV, or if any unusually high power frequencies or Temporary Over Voltages (TOV) are anticipated, contact your GE Sales Engineer for assistance.
Configuration
Protectors are available for single phase with neutral and ground, for three-phase wye with neutral and ground, or for three-phase delta with ground. (See figure 1)
Connections
Where applicable, it is important to minimize lead lengths to the TVSS for optimum protection. Larger wire sizes
