3.0 INSTALLATION

Patton's Model 571 and 581 surge protectors are easy to install
and are designed to operate transparently to your network. This
section describes connection procedures for both models.

3.1 PRODUCT APPLICATIONS

Both Models 571 and 581 protect 4 pins on the modular RJ-45 Cat­5 interface, and work in environments with data rates up to 100 Mbps.
The following descriptions will give you a general guideline for installing
the units in your Cat-5 environment.

3.1.1 POINT-OF-USE APPLICATION (MODEL 571)

The Model 571 is designed for installation on LAN equipment in a
typical office environment (see Figure 1, below). For best results the
Model 571 should be connected as close as possible to the
communication port of the device to be protected . Also, the flat
braided grounding wire on the Model 571 should be attached to the
grounded metal frame of the device being protected.

2. Install the Model 571/581 between the incoming UTP line and the
protected equipment (see Figure 3, below). This installation
requires a straight through Cat-5 patch cable with modular RJ-45
connectors (supplied with unit).

Note: The Model 571/581 provides bi-directional clamping
protection. Therefore, the network and equipment cables may be
connected to either end.

3. Locate a metal chassis ground on the equipment to be protected.
This is often a hex screw on a D-shell or AUI connector.
Sometimes a metal back panel is attached by screws, one of which
can be used for chassis grounding. If you cannot locate a chassis
ground connection on your equipment, contact Patton Technical
Support at [phone]; http://www.patton.com; or,
[e-mail].

4. Connect the braided ground strap directly to the chassis ground
connection you have located (see Figure 3, above).

Caution

: Surge energy may run both directions on the ground

strap. To provide the best protection, it is essential that the ground
strap on the Model 571/581 be connected to the chassis ground of
the protected device. Do not lengthen the ground strap of the
Model 571/581 or connect to a ground other than chassis ground
unless instructed to do so by Patton Technical Support.

APPENDIX B

EIA/TIA TSB-40A COMPLIANCE

The Model 571/81 series surge protectors have been designed to

conform to stringent EIA/TIA TSB-40 standards as required for all
Category-5 connecting hardware. These standards specify the
capacitance and near end cross-talk (N.E.X.T) to insure proper
operation of ALL connected equipment. Specific test results are shown
in the tables on the following pages*.

*Note: All test results are for the Model 571/581 alone, not

including the standard 6” (15.25cm) patch cable that is
shipped with the unit.
