IMPORTANT NOTICE THE ENTIRE CONTENT OF THIS MANUAL MUST BE READ AND FULLY UNDERSTOOD BEFORE ATTEMPTING ANY INSTALLATION OR ENERGIZATION OF THE SPD. If there are any questions about the operational status, or integrity of the electrical system prior to installation of the SPD, please consult a qualified trained electrician before attempting to continue.
PRODUCT DESCRIPTION: GE TRANQUELL Series Type 2 Surge Protective Devices (formerly called TVSS), are for installation on low voltage electrical distribution systems. GE SPDs are designed to protect electrical equipment loads against the damaging effects of transient voltages that can be induced or generated as a result of remote lightning, power equipment switching or high frequency disturbances.
MAXIMUM CONTINUOUS OPERATING VOLTAGE (MCOV) This value defines the maximum line-to-line or line-to-neutral continuous AC voltage that can be safely applied to the protector. MCOV levels for GE Tranquell Series SPDs are set at 115% of nominal system voltage. For 120-volt AC systems, the MCOV is 125%.
WARNING THE EQUIPMENT COVERED BY THESE INSTRUCTIONS SHOULD BE INSTALLED AND SERVICED ONLY BY COMPETENT, QUALIFIED 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. PRE-INSTALLATION REQUIREMENTS: Prior to energization of the GE Tranquell SPD, it is critical that the following items have been addressed.

WARNING POWER MUST BE PROVEN DISCONNECTED BEFORE STARTING INSTALLATION, INSPECTION OR MAINTENANCE. FAILURE TO DO SO MAY CAUSE SERIOUS INJURY, DEATH AND/OR PROPERTY DAMAGE. INSTALLATION: Before attempting installation, make sure that the pre-installation requirements of this manual have been satisfied. If the status of the pre-installation requirements are not known, do not attempt to continue. 1. MOUNTING The GE Tranquell Wall Mounted SPD must be installed as close to the protected circuit as possible.

INSTALLATION (CONT.): 3. CONDUIT FITTINGS A ¾” NPT Offset style conduit nipple is provided as an integral part of the SPD on WM and WMF models for routing the wiring pigtails into the electrical panel. Caution: Do not attempt to remove, twist, turn or alter the integral conduit nipple. This will cause irreversible damage to the SPD internal wiring and will void the warranty. An additional conduit spacer, adapter or fitting should be used only when necessary to facilitate installation.

WARNING UPON ENERGIZATION OF THE SPD, IF ANY OF THE LAMPS OR ALARMS INDICATES AN ABNORMAL CONDITION, POWER SHOULD PROMPTLY BE DISCONNECTED FROM THE SPD. THE ELECTRICAL SYSTEM SHOULD BE INSPECTED AND THE PRE-INSTALLATION REQUIREMENTS SHOULD BE VALIDATED. DO NOT ATTEMPT TO LEAVE POWER APPLIED TO THE SPD, OR REENERGIZE THE SPD IN THE EVENT OF AN ALARM CONDITION. PLEASE CONTACT YOUR LOCAL GE REPRESENTATIVE FOR FURTHER ASSISTANCE.
SERVICING / TROUBLESHOOTING: The GE Tranquell Series SPD contains no user serviceable parts and requires no calibration. The rugged design of the SPD should provide many years of service. Should a condition occur that results in premature failure of the GE Tranquell SPD, the integral fusing or required circuit breaker will safely interrupt current flow through the SPD without disrupting power to the protected equipment.
