IMPORTANT SAFETY INSTRUCTIONS • SAVE THESE INSTRUCTIONS
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. Connect wires as shown in figure 1.
3. 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.
• IG3240FMP33 is also available for flush mount applications.
2. Connect the green wire from the SPD to the ground bus in the panel.
• Connection may also be made to the neutral/ground bus bar if panel does not have a separate ground bus bar.
3. Connect the white wire from the SPD to the neutral bus bar in the panel as shown in figure 2.
4. 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.
5. 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.
