DescriPTion
Knock-out mounted and cabinet type hard-wired Transient Voltage Surge
Suppressors for use at main panel or sub-panel locations.
aPPlicaTion
Protects electronic equipment from damaging voltage transients. These high
energy impulses are caused by electrical disturbances conducted through
utility powerlines or internal sources such as adjacent equipment switching on
the same branch circuit or service panel feed. These impulses can result in
catastrophic damage to connected electronic equipment. More likely is less
obvious damage in the form of information errors and erratic operation, which
eventually lead to permanent damage.
Pass & Seymour’s panel mount Transient Voltage Surge Suppressors, when
installed at the main service entrance or sub-panel locations, will help limit
transient voltage disturbances to a level tolerable to the connected equipment.
Supplementary protection is also recommended in the form of receptacle or
portable cord connect/direct plug-in devices and can be provided by Pass
& Seymour. Please contact Pass & Seymour for additional device or Catalog
Number information.

1. Insure that all power is removed before beginning installation.
2. Mount the surge suppressor through a knockout on the service panel. The
unit should be positioned for a minimum of wire length between itself and the
input power terminals of the service panel. Remove nut from threaded nipple
of surge suppressor, place nipple through knockout and reapply nut.
3. Connect black wires to line buss bars through a circuit breaker rated 30
amperes or less, capable of delivering not more than 42,000 amperes of RMS
symmetrical current. Circuit breakers should be located as close as possible
to the input power terminals of the service panel.
4. Connect the white wire to the neutral bar and the green wire to the ground
bar. Keep wires as short as possible. Avoid bending the wires at sharp angles.
5. Apply power. The surge suppressor is protecting when the two green lights
are illuminated. If green lights do not come on, remove power and check
all connections to the unit. If lights still do not come on, contact Pass &
Seymour/Legrand at 800-223-4185.
6. Periodically monitor the status of the green lights. Loss of protection is indi-
cated by a green light (or lights) turning off. There are no user serviceable
parts, contact Pass & Seymour/Legrand for replacement.
caTalog numbers 1224-sm, 1220-Twm, 2748-Twm, 240-TDm
1. Insure that all power is removed before beginning installation.
2. Mount the surge suppressor as close as possible to the service panel. The
unit should be positioned for a minimum of wire length between itself and the
input power terminals of the service panel.
3. Remove the fitting from the conduit provided and cut the conduit so that it will
fit between the TVSS and the knockout selected on the service panel. Feed all
wires through the conduit into the panel and tighten all fittings.
4. Connect black wires to the line 1 and 2 or phase A, B, and C buss bars through
circuit breakers rated 20 amperes or less, capable of delivering not more
than 65,000 amperes of RMS symmetrical current. Circuit breakers should be
located as close as possible to the input power terminals of the service panel.
For Catalog Number 240-TDM, insure that the black wire marked “Phase B”
is connected to the high leg, failure to do so will result in damage to the surge
suppressor.
5. Connect the white wire to the neutral bar and the green wire to the ground
bar. Keep wires as short as possible. Avoid bending the wires at sharp angles.
6. If not using remote supervisor circuit (RSKIT), cut and dress the blue, orange,
and yellow wires into the conduit. If utilizing the RSKIT, see the directions for
connection under Catalog Number RSKIT.
7. Apply power. The surge suppressor is protecting when the green lights are
illuminated and the red light is off. If green lights do not come on, remove
power and check all connections to the unit. If lights still do not come on,
contact Pass & Seymour/Legrand at 800-223-4185.
8. Periodically monitor the status of the green and red indicators. Loss of protec-
tion is indicated if a green light or lights turn off, or if the red light turns on.

1. Insure that all power is removed before beginning installation.
2. Install the side mounting flanges to the holes provided in the side of the
surge suppressor (hardware included), so that the mounting holes are against
the wall.
3. Determine where the surge suppressor is to be mounted, allowing for mini-
mum lengths of wire between itself and the input power terminals of the ser-
vice panel. Punch or cut proper size hole in the side of the surge suppressor
closest to the knockout to be utilized in the service panel. Mount surge sup-
pressor and connect to service panel via conduit.
4. Connect black wires (line or phase) to the screw terminals connections of the
rotary disconnect switch through circuit breakers capable of delivering not more
than 200,000 amperes of RMS symmetrical current. Circuit breakers should be
located as close as possible to the input power terminals of the service panel.
Run 1/0-14 AWG wire from the service panel through the conduit into the surge
suppressor. It is recommended that green colored wire be used for ground, white
colored wire for neutral, and black colored wires for line or phase connections.
5. Connect black wires (line or phase) to the screw terminal connections of
the rotary disconnect switch. Connections should be made to the terminals
opposite those with wires connected to the line or phase modules. Connect
the green (ground) wire to the screw terminal marked “Transient Ground.”
Connect the white (neutral) wire to the screw terminal marked “N.” Keep
all wires as short as possible. Avoid bending the wires at sharp angles. To
obtain the UL1449 surge voltage rating marked on the device, wiring must
enter the device as shown in the accompanying diagram. Utilizing any other
wiring location will yield different suppression levels.
6. If utilizing the remote supervisor circuit RSKIT, see the directions under
Catalog Number RSKIT.
7. Apply power. The surge suppressor is protecting when the green lights are
illuminated and the red light is off. If the green lights do not come on, check
to make sure the rotary disconnect switch on the front panel is in the “on”
position. If it is, remove power to the surge suppressor and the service panel
and check all connections. If lights still do not come on, contact Pass &
Seymour/Legrand at 800-223-4185.
8. Set the front panel alarm enable/disable switch to the desired location.
9. Periodically monitor the status of the green and red indicators. Loss of
protection is indicated if a green light or lights turn off and the red light turns
on. Loss of protection is also indicated by an audio alarm if the front panel
switch is set to the enable position.
10. The protection modules in these units are replaceable, contact Pass &
Seymour/Legrand for replacement numbers.
