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 you have any questions while
installing or using this product, please do not hesitate to contact Patton
Electronics Technical Support at [phone].
2.1 FEATURES
• Uses a multi-stage hybrid circuit for the best possible protection
• Handles surge energy up to 1.5 kW
• Conforms to the UL497A telco specification (except E1 versions)
• Available for ISDN-U (8-wire), ISDN-ST (4-wire), T1, E1, ISDN
PRI, DDS, leased line and dial up configurations
• Diverts surges directly to chassis ground through braided metal
ground strap
• Equipped with two RJ-45 jacks or four BNC connectors
• Easy to install
• Made in the U.S.A.
2.2 DESCRIPTION
The potential threats to ISDN and Telco hardware are vast:
lightning, AC power induction, electrostatic discharge, ground potential
differences, EMI/RFI interference and more. The Patton Model 552 has
been designed to greatly reduce these risks. Just attach one unit to
each of your telco ports and rest easy.
The Model 552 connects directly between twisted pair telco cables
and their respective I/O ports. Grounding is accomplished using an
external ground strap that provides a separate unit-ground to chassis-
ground connection. By shunting threatening voltages directly to chassis
ground, the Model 552 insures data integrity and protects connected
equipment from damage.
The Model 552 uses a solid state design and sophisticated
multistage hybrid circuits to achieve maximum protection without
performance loss. Eight versions are available: Model 552-ST, 552-D8,
and 552-L8 protect all 8 pins; Model 552-D6 protects six pins; Models
552-DDS, 552-D4, 552-U, 552-L4, 552-E1, 552-E1 CX, and 552-T1
protect four pins; and, Model 552-D2 protects two pins. All versions
provide up to 1500 Watts of data line protection.
NOTE: Model 552-L8 may be used to protect Leased Line, DDS,
T1, E1, ISDN PRI, and ISDN BRI “U” and “ST” interfaces.
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 552 is easy to install and should give you years of
trouble-free service. Here are a few simple instructions to help you get
things hooked up right.
1. Unplug (disconnect) the existing connection between the network
cable and the equipment’s I/O port.
2. Install the Model 552 between the incoming network cable and the
protected equipment using the 6 inch (15.2cm.) modular patch
cable (supplied). Place the surge protector as close as possible to
the device being protected.
NOTE:To ensure proper operation of the Model 552, make sure
that your equipment is connected to the protected side of the
Model 552. See Figure 1 below.
NOTE:The Model 552-E1 CX has two pairs of BNC jacks that
connect one to one through the device. See Figure 2 below.
3. Connect the braided ground strap directly to a chassis ground
connection on the protected device. If you are not sure where to
locate a chassis ground connection on your equipment, consult the
equipment's user manual or contact the manufacturer. Correct
ground connection is critical for proper operation of the Model 552.
