There are two (2) terminals on the
liNE sidE
and three (3) wires on the
EQuiPMENT sidE
of this surge protection device (SPD). The Ground lead is considered ground
for both the input terminal and the equipment wire connections. For the best results, the ground wire should be connected to a low impedance ground or the green
wire AC power ground. It is recommended that a #14 standard wire be used for this connection.
Field (current) loops or incoming signal/data lines are to be cut or disconnected from the equipment to insert the SPD. The
liNE sidE
terminals of the protector are to
be connected to the field loop wires. The
EQuiPMENT sidE
of the protector is connected to the equipment/controller, etc. The location of the protector should be as
close to the equipment requiring protection.
