Installation Instructions
PF420
Mounting
The SurgeX PF420 is designed to be mounted on a flat, vertical surface. Secure the
unit by fastening at the corners with appropriate screws. This product must not be
flush mounted or set between wall studs as overheating can occur under such
conditions. Use caution when removing knock-outs so that damage does not occur
to internal components.
Connection
The SurgeX PF420 provides four identical circuits, each rated at 120 Volts and 20
Amps, providing a total capacity of 80 Amps. This product shall be wired only by
qualified Electricians using 12 AWG conductors as specified in Article 310 of the
2005 National Electric Code, as set forth in Table 310.13. Any type of conductor
suitable for use in wet or dry locations such as (but not limited to) THHN, THHW,
THW, THWN, or TW shall be considered acceptable if local Code permits. Each
circuit must be protected by a 20 Amp circuit breaker.
A special terminal is provided for each circuit to carry an Isolated Ground
(technical ground) though the unit. These terminals have no connection to the
chassis ground or to the unit itself and their sole purpose is to provide a convenient
way of joining isolated ground wires.
The four higher terminal blocks are for the Line connections, with the
corresponding Load terminal block for that circuit directly below it.

Line Connection
Connect the electrical service from the load side of the circuit breaker to the upper
terminal block as follows:
Live (Black) wire to the terminal labeled “LINE”
Neutral (White) wire to the terminal labeled “NEUT”
Ground (Green) wire to the terminal labeled “GRND”
Isolated Ground wire (if used) to the terminal labeled “ISO GND”
Load Connection
Connect the equipment circuit (load) to the lower terminal block as follows:
Live (Black) wire to the terminal labeled “LOAD”
Neutral (White) wire to the terminal labeled “NEUT”
Ground (Green) wire to the terminal labeled “GRND”
Isolated Ground wire (if used) to the terminal labeled “ISO GND”
Indicator Light
There are four green indicator lights on the front of the unit, one for each circuit.
These green lights are Self-Test indicators that indicate power is applied to the unit
and also that the internal surge protection circuitry on each circuit is fully
functional.
