INSTALLATION INSTRUCTIONS
and
OPERATIONS MANUAL
TURN OFF POWER TO THE ELECTRIC SERVICE OR PANEL AND TO EQUIPMENT TO BE
PROTECTED BEFORE INSTALLING ANY SURGE PROTECTION DEVICE. ALL WIRING
SHOULD COMPLY WITH THE
NATIONAL ELECTRIC CODE AND LOCAL ELECTRIC CODES.
INSTALLATION
1. TEST and verify system voltage to assure proper selection of the Surge Protection Device (SPD) in accordance with the wiring
diagrams shown on page 2. Turn OFF the electric power to the panel.
2. CONFIRM that the Surge Protection Device is the proper voltage configuration for this installation. Refer to the installation diagrams for additional information.
3. SELECT a location to mount the SPD cabinet. Mount as close as possible to the electric panel or individual piece of equipment
to be protected. The SPD should be mounted on a flat vertical surface that can support the weight of the device. Consideration
should be given to the available knockout positions in the panel when deciding where to locate the SPD. All wire leads should be
kept as short as possible to insure optimum operation.
4. The internal Ferraz Shawmut VSP fuses are the prime current protection devices for this SPD; but safety and good wiring practice
suggests that lead wires be connected to a multi-pole breaker. Use a 60 to 100 amp breaker with the appropriate number of
poles. Panel breakers will not trip from surge activity due to their inherent slow response.
NOTE:
For installations connecting directly to bus bar, the PG Series must be less than ten feet (10’) wire distance from the bus bar to qualify
the internal fuses as the primary overcurrent device in accordance with the NEC 10 foot rule 240-21(b).
MOUNTING
1. Attach the upper and lower mounting rails to the PG Series Cabinet using the screws provided.
2. Pre-drill holes in the surface on which the PG Series will be mounted. Use at least four (4) appropriate size mounting screws
or bolts.
3. Open the hinged cover on the PG Series unit by unscrewing the locking bolts in the cover.
4. Remove the deadfront panel.
5. Select and remove the proper size knockout from the PG Series cabinet. Install conduit, sealtite or other proper wire protection between the panel and the SPD.
WIRING
1. Refer to the chart on page 2 for the proper wire size.
2. Measure and cut all leads to proper length, keeping in mind that leads should be as short and straight as possible.
3. Tie wrap or tape all wires together to minimize inductive coupling.
4. Route the wire lead bundle through the conduit to the panel.
5. Connect the GROUND (green) lead to the ground bus in both the PG Series and the electric panel.
6. If used, connect the NEUTRAL (white) to the neutral terminal in the PG Series and the neutral bus in the electric panel. If
installing at the main distribution panel, the neutral and ground leads could terminate at a common bus bar in the panel.
7. Connect the phase leads to the proper connectors in the PG Series. Then connect them to the appropriate breaker connections in the electric panel. NOTE: For HIGH LEG DELTA, make certain that the high leg is connected to the designated position in
the PG Series.(Refer to Figure 3)
8. Connect wires to the alarm relay leads. Alarm wires should be routed through a knockout that is separate from the power leads.
(Refer to alarm wiring drawings on page 2)
9. CHECK all connections for tightness.
10.REPLACE Dead-front panel.
11. Close and secure the hinged front cover, remembering to replace all
of the locking bolts.
12.Turn power to the unit ON.

NOTE: These wiring diagrams show installation of the PG
Series unit on the load side of a breaker. While these units have
internal fusing, it is recommended that a 60 to 100 amp breaker
be used as a disconnect. Refer to installation instruction number
4 on page 1.

ALARM RELAY OUTPUT CONNECTIONS
1. Two Wire Closed Loop: Connect feed wire to the Common (C)
wire and return wire to the Normally Opened (N/O) wire. During
normal operation, the contact will be closed between C and N/O.
The contact will open during an alarm condition.
2. Two Wire Opened Loop: Connect the feed wire to the Common
( C ) wire and return wire to the Normally Closed (N/C) wire.
During normal operation, the contact will be opened between C
and N/C. The contact will close during an alarm condition.
3. Three Wire Supervised Loop: Connect feed wire to the
Common (C) wire, one return wire to the Normally Opened (N/O)
wire and the second return wire to the Normally Closed (N/C)
wire. During normal operation, the contact will be closed between
C and N/O and opened between C and N/C. An alarm condition
will reverse the condition.
4. Consult the instructions for your specific monitoring system for
additional information.
