INTRODUCTION
The PG60-80-100 Series is designed to be installed in very close prox-
imity to the power bus of an electric distribution panel or electric panel-
board. It can be used with most panels or panelboards in distribution
today.
The PG60-80-100 Series offers peak surge amperage protection
levels of 60 kAto 100 kA
per mode. It is designed to be easily mounted
above or below the panelboard. Provisions have been made with a
reversible cover plate to keep the instructions and indicators in a user
friendly position. Standard features include all mode protection, multi-
mode LED indicators that show full protection, diminished protection and
lost protection for all phases. A
form C relay for remote alarm indication,
audible trouble alarm with test and silence switch are also standard
equipment.
The system is comprised of three sections; outer housing, cover plate
and inner module. Each section is engineered to make the installer/ser-
vice technician's task as easy as possible. A
description of each section
and the function follows.
Outer Housing - Metal housing measuring 20" wide x 16" high x 6"
deep. The outer housing contains the inner housing. connection lugs for
each phase, neutral and ground, connections for the form C alarm relay
and the audible alarm test and silence switch.
A5/8" flange on the forward side of the housing has ten (10) threaded
holes that are used to attached the cover plate. Four (4) mounting holes
are located in the back surface of the housing for mounting. It is sug-
gested that all four (4) fasteners be used to secure the outer housing.
Cover Plate - Metal plate measuring 19 13/16" wide x 15 13/16" high.
The cover plate contains ten (10) holes located around the edges that
matched the threaded holes in the outer housing and are used to secure
the cover plate to the outer housing. The cover plate is reversible and
has an identification label on both front and reverse sides. The labels
are mirror images of each other and selection of which side to use
depends upon the placement of the outer housing. (This process will be
explained in the installation section that follows.)
Inner Module - Metal box measuring 13 3/16" wide x 9 3/4" high x 4
15/16" deep including the mounting rails that are part of the module.
The inner module is fastened to the outer housing with four (4) bolts
through the mounting rails. Module identification and wiring diagram
labels are attached to the inner module. The inner module contains all
of the surge suppression, noise filtering, fusing, monitoring and reporting
components. Copper bus bars and terminal lugs extend from the inner
module.
NEC Section 285 requires that a SPD have a fault current rating equal
to or greater than the point of installation (switchboard or panelboard).
The PG60-80-100 Series is suitable for use on a circuit capable of deliv-
ering not more than 200,000 amperes (120/208-3Y , 120/240-2S,
120/240-3HLD, 277/480-3Ymodels). 480-3D models are rated at
25,000 amperes. Should you require a 480-3D model with a higher fault
current rating consider Intermatic PG2500/PG3000/PG3500 Series
which are rated at 200 kAIC.

BEFORE INSTALLATION
1.
All electrical wiring and connections should be installed by a
qualified electrician. All wiring must comply with the National
Electrical Code (NEC) and local codes.
2.
This Surge Protection Device (SPD) incorporates a NEMA 12
enclosure.
3.
The installation and operation of any Surge Protection Device
(SPD) requires proper grounding. A properly sized, insulated
grounding conductor is required. The grounding conductor should be
the same wire size (gauge) as the phase and neutral conductors
used for the SPD. Refer to Table 2 for recommendations.
4.
The service entrance and panel grounding configurations must
comply with the National Electrical Code and all local codes.
3.
Select a location opposite the incoming feed to the panelboard.
The SPD must be mounted in an area that provides sufficient work-
ing space around the panelboard and SPD cabinet.
5.
The collar and/or conduit used to connect this SPD to the panel-
board must be sized correctly for the gauge and length of wire
required. The length of conduit should allow no more than 1/16”
between the edge of the SPD cover plate and the panelboard cover.
6.
TEST and verify system voltage to assure proper selection of
the Surge Protection Device (SPD) in accordance with the wiring dia-
grams shown below and on the labels located on the inner module.

INSTALLATION (above panelboard)
1.
Turn OFF and LOCK the electric power supply to the panel-
board.
2.
SELECT the location where the Surge Protection Device
(SPD) will be mounted, above or below the electric panel.
Position the SPD adjacent to the electric panel with the bus bars
pointed toward the panel. NOTE: If the SPD is mounted below
the electric panel, the labels on the inner housing will be invert-
ed. Refer to INVERTED INSTALLATION section below for infor-
mation regarding the inverted installation. Align the SPD to allow
1/16” between the SPD cover plate and the cover of the panel-
board. The SPD should be secured to a flat vertical surface that
can support the weight of the device.
3.
Temporarily fasten the SPD to the vertical surface and mark
the location where a hole for the collar or conduit will enter.
Refer to Table 1 for acceptable locations on the bottom of the
Outer Housing that can be drilled for wire entry. Note that wiring
for the remote monitoring relay enters separate from the AC
power leads. Remove the SPD unit and drill a hole of sufficient
size to accept the collar or conduit connector. Attach the collar or
connector to the SPD outer cabinet and mount the unit with the
collar or connector inserted into the knockout in the panelboard.
4.
Use the proper gauge wire to connect each of the lugs on
the SPD to the appropriate points on the electric panel. See
Table 2 for recommended wire and breaker sizes. Use of a ded-
icated circuit breaker is optional since the SPD has integral
overcurrent fusing. The SPD can be connected through feed-
thru lugs on a panelboard. The SPD can be connected through
a breaker or direct tapped for Switchboard installations. Select a
position for the connection that results in the shortest lead
lengths between the SPD and the power bus. Leads should be
kept as short as possible to insure optimum operation. Measure
and cut all leads to proper length. Strip the ends of each lead
9/16" for the SPD terminal lugs and to proper length for the
breaker used. Connect the wire leads to the lugs on the bus
bars of the SPD. Torque the lugs 35 to 50 inch pounds per UL
486 torque tightening requirements.
NOTE: For safety, observe proper wire marking
conventions; BLACK for HOT, RED for HOT HIGH
LEG, WHITE for NEUTRAL, GREEN for GROUND.
5.
Route the wire lead bundle through the collar or connecter
into the electric panel.
6.
Connect the GROUND (green) lead to the ground bus in
electric panel.
7.
If used, connect the NEUTRAL (white) to the neutral bus in
the electric panel. If installing at a main electrical panel, the neu-
tral and ground leads could terminate at a common bus bar in
the panel.
8.
Connect the phase leads to the appropriate breaker in the
electric panel.
NOTE: For HIGH LEG DELTA, make certain that the
high leg is connected to the center bus bar position in
the SPD. (Refer to Figure 3)
9.
Connect wires to the alarm relay leads if used. Alarm wires
should be routed through a hole in the outer housing that is sep-
arate from the power leads. If the alarm relay is not used, leave
the wires in the low voltage section, they will have no power and
do not need to be capped. Refer to the alarm wiring drawings
on page 3 or on the wiring label on the inner housing for wire
designation.
10. CHECK all connections for correct torque.
