This Surge Protection Device (SPD) is a high performance device, designed to provide protection
for sensitive electronic loads connected to service panels, fire panels, or where the SPD is
directly connected to the electronic device. Maximum protection will only be achieved if the SPD
is properly installed.
Please read and follow the installation instructions carefully.
NOTICE: This SPD should be installed by a licensed contractor in accordance with the National
and Local Electrical Codes and the following instructions.
APPLICATION
Surge suppression for installations using an RJ45 connector on series voice or data 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 off the power to the circuit before beginning installation.
2. Using an RJ45 tipped supply/patch cable, connect the cable assembly to the “IN” side of the MRJ.
3. Using 3’ RJ45 tipped patch cord, connect the equipment to the “OUT” side of the MRJ.
4. Connect the ground lead to the ground terminal on the MRJ product. Make sure the ground lead
is as short as possible.
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.
5. For mounting, use the double sided tape (supplied), or two #8 screws (not supplied).
6. After all connections have been made and no hazards exist, restore power.
