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.
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.
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. For best
performance from SPD the maximum recommended circuit breaker size of
240 VAC, 20 A, 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.
