IMPORTANT NOTICE

THE ENTIRE CONTENT OF THIS INSTRUCTION MUST BE READ AND

FULLY UNDERSTOOD BEFORE ATTEMPTING ANY INSTALLATION

OR ENERGIZATION OF THE TVSS.

!

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.

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.

GE TR5451 and TR5452 Model Transient Voltage Surge Suppressors (TVSS) are
designed for installation on low voltage electrical distribution systems, protecting electrical
equipment loads against the damaging effects of transient voltages

Prior to installation of the TVSS, it is critical that the following items have been addressed.

O NOT ATTEMPT TO CONTINUE WITH THE INSTALLATION IF ALL OF THESE CONDITIONS HAVE NOT

D

BEEN MET, OR ARE UNKNOWN.

.

 Check the configuration and voltage supply ratings that will be feeding the TVSS

panel to ensure that the proper TVSS model number has been selected for your

PRE-INSTALLATION REQUIREMENTS (CONT.):

A

system. Refer to the “VOLTAGE RATINGS & POWER SOURCE
CONFIGURATIONS” chart below. The TVSS model number can be found on the
front of the unit.

 Verify that an NEC (National Electrical Code) compliant X0 bond has been made at

the upstream transformer that feeds the electrical supply panel. Per NEC 250.30, this
bond must be in place on all grounded electrical systems.

 The TR5451 or TR5452 model TVSS must be installed on a dedicated branch circuit

breaker. The maximum allowable rating for the circuit breaker is 30A / 22kAIC.

 Do not attempt to install the TVSS on the upstream (line) side of the Main Breaker or

Fuse.

 The TVSS should only be installed indoors in NEMA 1 type locations. Do not install

the TVSS outside or in wet locations.

FAILURE TO DO SO MAY CAUSE SERIOUS INJURY, DEATH
AND/OR PROPERTY DAMAGE.

Before attempting installation, make sure that the pre­installation requirements of this manual have been satisfied.
If the status of the pre-installation requirements are not
known, do not attempt to continue.

MOUNTING

1. TR5451 and TR5452 TVSS units are designed to be

mounted directly to the electrical panel through a ½”
knockout. Mounting feet are also supplied for instances
where direct connection to the panel is not practical. Select
a location that will allow the closest proximity to the breaker
that the TVSS will be connected to.

2. Use the ½” threaded fitting and spacer to secure the
TVSS to the Electrical Panel that is to be protected.
