INSTRUCTIONS:

Caution: Measure all voltages to insure applied voltage does not exceed the voltage rating of

the unit. Improper installation voids the warranty.
This unit must be connected in series with the equipment to be connected.

1. Connect the incoming wires to the "IN" connector.

2. Connect a CAT 5e patch cable from the "OUT" to the equipment to be protected.

3. Always have one common ground per system to eliminate the possibility of a differential in
ground potentials.
Ground Resistance Rule: Max ground resistance is 25 ohms, 5 ohms or less is optimum.
This cannot be an assumed value and must be measured to assure proper grounding.

4. For mounting, use double sided tape (supplied), or two (2) #8 screws (not supplied).
