2.0 GENERAL INFORMATION

Thank you for your purchase of this Patton Electronics product.
This product has been thoroughly inspected and tested and is
warranted for One Year parts and labor. If any questions or problems
arise during installation or use of this product, please do not hesitate to

2.1 FEATURES

• Multi-level surge protection

• Operation at Speeds up to 100 Mbps

• Four-wire protection on lines 1, 2, 3, and 6 on Cat-5 RJ-45

• EIA/TIA TSB-40A Category 5 Compliant

• N.E.X.T. better than -43 dB at 100 MHz

• Shunts surges directly to chassis ground

• Easy to install

• Made in the U.S.A.

2.2 DESCRIPTION

Devices that connect to Category-5 cabling systems are routinely
threatened by unwanted electrical energy (lightning, AC power
induction, ESD and more). Higher speed devices–such as those
operating at 100 Mbps–are especially vulnerable to the effects of these
hazards, which can include data loss and hardware damage.

The Patton Model 571 and 581 Series Surge Protectors provide
effective surge protection for devices operating in Category-5 Cabling
Systems. The Model 571 is specifically designed for point-of-use
installation; the Model 581 is designed to be installed at the building
entrance. Both models use a multi-stage Silicon Avalanche Diode
circuit, and will continue functioning while handling the appropriate IEC

801.5 surges applicable to their use (see the tables in Appendix B).
Both the 571 and 581 will additionally protect against surges up to and
exceeding 2kV/1kA in fail-safe mode.

Models 571 and 581 support a wide range of balanced interfaces
running over 4 wires. Highlights include a low insertion loss (less than

0.4dB at 100MHz) and minimal near end cross talk (greater than -43
dB at all frequencies up to 100 MHz). Grounding is accomplished via an
external ground strap that provides a separate unit-ground to chassis­ground connection.

Warning: This product will not provide complete protection
should your equipment or building be subject to a direct
lightning hit.

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.

Figure 1. A typical Point-of-Use Application for the Patton Model 571.

3.1.2 BARRIER APPLICATION (MODEL 581)

The Model 581 is a more robust protector than the Model 571, and
is designed for use as a barrier protector on LAN equipment in campus
networks. Applications include cable runs between buildings, cable
runs between floors on multi-story structures, and as a higher capacity
replacement for the Model 571.

The Model 581 is also well suited for use in severe lightning areas,
heavy industrial environments, and installations with heavy machinery
in the direct vicinity of sensitive LAN equipment and cabling. Figure 2
(above) shows a typical application for the Model 581. For best results,
the braided grounding strap on the Model 581 should be attached to the
grounded metal frame of the device being protected. When installation
is made at a barrier, such as an external wall, the braided strap should
be connected to a nearby electrical ground.

3.2 INSTALLATION PROCEDURES

In order to operate as designed, the Model 571 and 581 must be

connected correctly

to your Cat-5 network. Please read all the

instructions below and follow them carefully.

Connection of the Model 571 or 581 to an I/O Port

1. Turn off equipment power and unplug (disconnect) the existing
connection between the UTP cable and the equipment’s I/O port.

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.

Connection of the Model 581 at a Barrier (Wall, Bldg Entrance, etc.)

1. Disconnect the UTP cable from the wall jack or patch panel jack.

2. Install the Model 581 between the UTP line and the jack. 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 an electrical ground nearest the jack. Often this will be on
an electrical panel or subpanel. If you cannot locate a nearby
electrical ground, contact Patton Technical Support at: (301) 975-
1007; http://www.patton.com; or, [e-mail] to
discuss an alternative grounding solution.

4. Connect the braided ground strap directly to the electrical ground
you have located. The best way to make this connection is to
attach the braided metal strap to a metal panel or wallplate screw
using a hex nut or screw.

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 581 be connected to an electrical ground.

APPENDIX B

MODEL 571/581 INTERNATIONAL ELECTROTECHNICAL

COMMISSION (IEC) COMPLIANCE

Meets IEC standards 801.2, 801.4 and 801.5 (CE Mark)

Effective January 1996 the European Economic Community will

require that all electronic devices be tested and comply with all
applicable International standards relating to the product type and
category of use. Electromagnetic Compatibility Directive 89/336/EEC
specifically addresses communication line surge protection devices,
since conformity to immunity standard EN50082-1:1992 is mandatory.
The EN50082-1:10992 standard incorporates International
Organization for Standardization (ISO) publications 801.2 and 801.4,
which describe Electrostatic Discharge and Electrical Fast Transient
requirements. ISO 801.5 describes Surge Immunity Requirements and
is expected to be adopted as a mandatory requirement under
EN50082-1 by the Technical Committee. in 1996. Any protector sold
into the international community must meet these standards. This
device has been tested* and found to comply with these standards as
evidenced by its CE mark.

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

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