3.0 INSTALLATION
Patton's Model 509 units are 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. Check the label of the Model 509 to be sure that you have the
correct clamping voltage for your system. The Model 509/25 is for
RS-232 systems. The Model 509/6 is for RS-422 systems.
2. Unplug (disconnect) the existing connection between the coaxial
cable and the equipment’s I/O port.
3. Install the Model 509 between the incoming coax and the protected
equipment (see below). Place the surge protector as close as
possible to the device being protected.
4. 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 509.

Thank you for your purchase of this Patton Electronics product.
This product has been thoroughly inspected and tested and is

2.1 DESCRIPTION
Transient overvoltages can be coupled to data lines from various
sources: lightning, AC power lines, elevator motors, factory equipment,
even UPS devices. Data lines running near power, control or telephone
cables are subject to short duration pulses approaching several
thousand volts. Patton Electronics surge protectors use the latest in
transient surge suppression technology to guard against potential data
loss and hardware damage due to transient surges. The Model 509
protects all 9 pins of the RS-232 or RS-422 interface. Surges are
shunted directly to chassis ground via the metal D-shell connector
Warning
: These products will not provide complete protection
should your equipment be subject to a direct lightning hit.
2.2 SURGE PROTECTION BENEFITS
The method of surge protection used in the Model 509 yields four
important benefits to your system:
1)
High Surge Capability
.
The 509 can dissipate up to 1500
watts (10 x 1000μSec) in compliance to IEC 801-5 Level 3
(2kV);
2)
Quick Response
.
The 509 has a fast response time of 1.0
picosecond at the componet level and less than 0.5
microsecond installed;
3)
Low Insertion Loss
.
Connect the 509 directly to RS-232
ports with minimal loss to your system: about the same as a
gender changer;
4)
"
Fail Open Design"
.
Unlike some other surge suppressors,
the 509 fails "open" if system experiences a direct lightning
strike or other extreme transient above the rating of the
protector. This means that if the surge suppressor fails, data
and surges are both shunted to ground instead of back into
your equipment.
