Legrand PA120Y - Manual

PA and PB Series Surge Protection Devices (SPD) from Legrand/Wiremold are designed for use at the service entrance,
distribution or branch panel, or at sensitive equipment. Units with an “-A” suffix include remote monitoring contacts; units with
a "-B" suffix include a noise filter. Units with suffix “-AB” include both remote monitoring contacts and noise filter options.
The following tools are required to mount and install the
surge protector:
1. Electric Drill
2. Hole Saw (1 1/8" [29mm] typical) or other knockout
device. (Or use pre-punched knockout on electrical panel.)
3 Wire cutter stripper for #10 AWG wire.
4. Miscellaneous hand tools.
PREPARATION
The following materials are required to mount and install the
surge protector:
1. Nipple (1" [25mm]) close metallic nipple for typical
installations.
2. Connecting wire: #10 AWG stranded.
3. Fasteners appropriate for the wall type where the SPD is
to be mounted. (Unit features built-in mounting holes,
11/64" [4.4mm] diameter.)
CAUTION
• Installation should be performed by a qualified electrician.
• Read all instructions prior to installing this device.
• TO AVOID FIRE, SHOCK, SERIOUS INJURY OR DEATH, TURN OFF POWER TO ELECTRICAL PANEL AND
EQUIPMENT TO BE PROTECTED PRIOR TO INSTALLATION OF THE SURGE PROTECTOR.
• PA and PB Series Surge Protection Devices are not lightning arrestors. They are not designed to
provide protection against direct lightning strikes or against a sustained overvoltage condition.
1. Test and check system voltage to verify proper surge protector selection. TURN OFF POWER TO ELECTRICAL PANEL.
2. Remove the cover from the electrical panel.
3. The SPD must be connected through a dedicated circuit breaker or fused disconnect switch. The breaker (or disconnect
switch) will provide a means of removing power to the unit for maintenance.
Use a 30 amp circuit breaker with an interrupt rating of at least 5,000A RMS, or fused disconnect switch (customer supplied).
Use a three pole breaker for three phase systems, a two pole breaker for 120/240V systems when configuring for
240V, two phase, and a single pole breaker when configuring a 120/240V unit for 120V single phase.
NOTE: Locate the SPD as close to the breaker as possible in order to minimize the connection length between
the panel power lines and the SPD.
4. Unscrew the four (4) nuts on the front of the unit and set them aside. Carefully remove the lid of the SPD; note that the
circuit board is attached. Place the lid with attached board in a safe location where it will not be exposed to dirt,
dust or physical impact.
Legrand/Wiremold electrical systems conform to and should be
properly grounded in compliance with requirements of the current
National Electrical Code or codes administered by local authorities.
All electrical products may present a possible shock or fire
hazard if improperly installed or used. Legrand/Wiremold electrical
products may bear the mark of a Nationally Recognized Testing
Laboratory (NRTL) and should be installed in conformance with current
local and/or the National Electrical Code.
