INTRODUCTION
Transient voltage surges are short-term deviations from a
desired voltage level or signal that can occur at any time.
Such changes can result in an electronic device
malfunction, or cause extensive damage. Also termed
"spikes" , these occurances take place as a result of
magnetic field/inductive coupling or whenever the line
current is interrupted. They can originate from either
inside a facility, or derive from outside utility lines.
Sources within a facility involve loads that are switched,
such as electric motors that are turned ON and OFF.
Outside transient influences involve utility grid switching.
DESCRIPTION
Leviton Panel Mounted devices are designed to provide
protection for microprocessor-based equipment in
industrial and commercial establishments from high
voltage transients.

WARNING: IF CONDUIT IS USED, AGREEN GROUND
WIRE MUST BE CONNECTED TO GROUND LUG.
FAILURE TO DO SO MAY RESULT IN FIRE AND/OR
SHOCK.
CAUTION: USE THIS DEVICE ONLY WITH COPPER
OR COPPER CLAD WIRE. WITH ALUMINUM WIRE USE
ONLY DEVICES MARKED CO/ALR OR CU/AL.
1. RESTORE POWER, if necessary.
2. Measure panel voltage, L-N, to determine the system
voltage. System voltage must not exceed the specified
maximum continuous RMS voltage listed on the TVSS
device label.
3. TURN OFF POWER.
4. Mount the TVSS device as close as possible to the circuit
breaker panel. Connection lead length between the TVSS
device and circuit breaker box should be minimal for best
protection. The location should also permit good visibility
of the TVSS device’s diagnostic lights.
5. Remove the circuit breaker panel cover and determine
the breaker-panel wiring entry point relative to chosen
location of the TVSS device.
NOTE: Since the circuit breaker panel and the TVSS
unit have overlapping covers, installation should allow
at least 1" of clearance from the edge of the circuit
breaker panel cover.
6. For surface-mount installations: The TVSS device
may be connected using rigid conduit to any conduit
knockout hole.
NOTE: For surface mount installation of NEMA 4X
enclosure, drill a hole in the NEMA 4X enclosure in line
with the NEMA 1 enclosure knockout to be used. Install
weather-proof conduit and seals to maintain the NEMA
4 integrity.
7. For non-surface mount installations: Secure the
TVSS to the support stud in the wall by cutting a
10" x 10" mounting hole.
8. Remove TVSS cover and connect 3/4" flexible or rigid
conduit between circuit breaker box and the TVSS using
the shortest route possible.
9. Place the TVSS device outer enclosure into the
10" x 10" mounting hole and secure it to the
exposed studs.
10. Remove clear plastic terminal cover.
11. If necessary, remove the two corner screws and the two
stand offs used for securing the Black circuit enclosure
box to the TVSS cover, allowing the Black enclosure
box to be rotated (in 90°increments) to place the
terminal lugs as close as possible to the conduit
entrance of the TVSS device.
NOTE: Do not remove center enclosure screw.
12. Replace the two screws and the two stand offs.
WIRING PROCEDURE
1. Thread wire leads through conduit to the TVSS enclosure.
2. Connect wires per appropriate wiring diagram as
follows: Black to Phase (Line 1, Line 2, Line 3). White
to Neutral. Green to Ground. For 120V, 2-Wire +
Ground operation, connect the Black wire to L1, and
Jumper terminals L2 and L3 to L1. For 240V Single
Phase (120/240V Single Phase), connect one Black wire
to terminal L1, and the other to L2. Jumper L2 to L3.
Screw terminal torque requirements: #10 - #12AWG
(35 in.-lb.), #8 AWG (40 in.-lb.), #4 - #6AWG (45 in.-lb.)
3. Replace the clear plastic terminal cover.
4. Ensure ground wire is connected to outer enclosure.
5. Replace panel cover.
6. Select circuit breakers as close as possible to each
service entrance lug. 20A circuit breakers are
recommended, and may share TVSS device and
branch circuit leads. The breakers provide additional
failure protection as well as a TVSS connection and
servicing disconnect.
NOTE: Do not connect TVSS leads directly to service
entrance lugs. This may result in fire or shock.
7. Lead lengths should be as short as possible. Connect
the Black leads to each Phase through the selected
circuit breakers. Connect the White lead to Neutral as
close as possible to Neutral entrance service lug.
NOTE: Avoid long loops and do not coil extra lead wire.
8. Replace circuit breaker panel cover.
9. Restore power at circuit breaker or fuse. Installation is
complete.
NOTE: (Remote Connection) Relay status contacts
accommodate #20 - #12AWG wire secured to terminals
using 3.5 in.-lb. of torque. If surge protection fails,
continuity will be between the “NO” and “C” contacts.

TO OPERATE
1. The Green LED on the TVSS device should be ON.
2. If during normal operation the LED turns OFF, contact a
qualified electrician to determine if Phase power is
applied. If power is present, then a transient surge has
exceeded the TVSS device rating. The unit should be
replaced and/or upgraded as soon as possible.
