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.
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.
