Model IG1200RC3
Type 1 or Type 2 Surge Protective Device
INSTALLATION INSTRUCTIONS
Risk of Electric Shock
WARNING
• Thoroughly read instructions before installing unit.
• Installation and Service to be performed by a
qualified licensed electrician.
• Intended for indoor or outdoor use.
Type 1 installation:
A typical installation of a type 1 SPD will be connected between the secondary of the service transformer and the
line side of the service panel. This installation is intended to be installed without overcurrent protection to the SPD.
1. Determine location:
• Ensure conductor lengths are as short and straight as possible
for best performance. Do not coil excess wire. The SPD
functions best if all bends in wires are rounded, ideally to a 4”
radius. Hard 90 degree bend will reduce efficiency.
Cut all leads to the correct length. Do not coil excess leads.
• Install appropriate weatherproof fittings if the unit is to be
mounted outside.
2. Ensure all mounting and connections are correct and secure.
Once energized the green indicator LED will be ON and visible
through the cover of the SPD.
Type 2 installation:
A typical installation of a type 2 SPD will be connected to the load side
of the service panel and is intended to be installed with overcurrent
protection to the SPD.
1. Determining location:
• Ensure conductor lengths are as short and straight as possible
for best performance. Do not coil excess wire. The SPD
functions best if all bends in wires are rounded, ideally to a
4” radius. Hard 90 degree bend will reduce efficiency. Cut all
leads to the correct length. Do not coil excess leads.
• Install appropriate weatherproof fittings if the unit is to be
mounted outside.
• IG1240FMP33 is also available for flush mount applications.
2. Connect the white wire from the SPD to the neutral bus bar in
the panel as shown.
• Connection may also be made to the neutral/ground bus bar if
panel does not have a separate ground bus bar.
3. Connect the two black wires to a circuit breaker as shown in
figure 2. For best performance from SPD the maximum
recommended circuit breaker size of 240V, 20A, 2-pole should
be used.
4. Ensure all mounting and electrical connections are correct and
securely fastened. Once energized the green indicator LED will
be ON and visible through the cover of the SPD.
Maintenance:
¡
AC Voltage SPD:
• Periodically check SPD to ensure green indicator LED is ON.
If green LED is OFF protection has diminished and the SPD
should be replaced immediately.
• All wiring must comply with all state and local
electrical codes including the National Electrical
Code and/or Canadian Electrical Code.
• Suitable for use on a circuit capable of delivering
not more than 50,000 rms symmetrical amperes.
• This unit contains no serviceable parts.
• This product does not protect against direct
lightning strikes.
