NOTICE: This SPD should be installed by a qualified electrician in accordance with the National
and Local Electrical Codes and the following instructions.

APPLICATION

Surge suppression for indoor 120VAC and Telecommuni cation circuits.

INSTRUCTIONS:

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

the unit. Improper installation voids the warranty.

1. Turn the main breaker off before beginning installation.

2. Connect the telephone circuit wires prior to installing the DTK-1F31X.

3. Connect the incoming tip and ring from the RJ31X jack to the terminal block marked IN 1 and
IN 2.

4. Connect the outgoing wires to the protected equipment to the terminals marked OUT 1 and
OUT 2.

6. Securely fasten the DTK-1F31X to the receptacle using the supplied mounting screw.

7. Restore power to the circuit and make sure the LED is on indicating ground, power and
active surge protection.

8. Always have one common ground per system to eliminate the possibility of 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.
