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. 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.
• Bracket part number AG1BRKT is also available if needed.
2. Connect wires as shown within diagrams. If your application does not match one of the diagrams below consult your supplier.
3. Ensure all mounting and connections are correct and secure. Once energized the green indicator LED will be ON.
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.
• Bracket part number AG1BRKT is also available if needed.
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 if panel does not have a separate ground bus.
3. Connect black wire to circuit breaker.
4. Ensure all mounting and electrical connections are correct and securely fastened. Once energized the green indicator LED will be ON.
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.
