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.

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 wires as shown within diagrams. If your application does not match one of the diagrams below consult your

supplier.

3. 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.
