DEVICE CHARACTERISTICS
INSTALLATION INSTRUCTIONS
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.
