• Operates with either 4 or 20 Mbps ArcNet
• Provides separate connection to chassis ground for surge handling
• Easy to install
• Made in the U.S.A.
DESCRIPTION
The potential threats to your ArcNet LAN are vast: lightning, AC
power induction, electrostatic discharge, ground potential differences,
EMI/RFI interference and more. The Patton Model 533 has been
designed to greatly reduce these risks. Just attach one unit to each of
your ArcNet devices and rest easy.
The Model 533 connects directly between ArcNet data cables and
LAN I/O ports. By shunting all threatening voltages to the chassis
ground, the Model 533 insures the integrity of the data in your LAN and
protects connected equipment from damage. Using an all solid state
design and sophisticated multistage hybrid circuits, these units can
handle up to 1.8 KiloWatts of electricity. Grounding is accomplished via
an external ground strap that provides a separate unit-ground to
chassis-ground 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 533 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 coaxial
cable and the equipment’s I/O port.
2. Install the Model 533 between the incoming coax cable and the
protected equipment (see below). Place the surge protector as
close as possible to the device being protected.
3. Connect the braided ground strap directly to a frame ground
connection on the protected device. If you are unsure where to
locate a frame ground connection on your equipment, consult the
equipment's user manual or contact the manufacturer—the ground
connection is critical for proper operation of the Model 533.
T-Splitter Model 533 MFF:
1. Remove the existing T-splitter from the Network Interface Card and
disconnect the coaxial cables.
2. Install the Model 533 directly on the Network Interface Card and
reattach the coaxial cables.
