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
(301) 975-1007

; or,
.
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
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.
