3.0  MODEL 504 & 505 INSTALLATION

The Patton Models 504 & 505 are simple to install and require no

user configuration.  Follow these installation steps:

1) Be sure the metal D-sub connector on the device you are 

protecting is connected to frame ground.  If not, see step 4, 
below.

2) Plug the DB-25 connector of the Model 504 or 505 

directly

into 

the DB-25 Serial port of the device you are protecting.  Use of 
a serial cable reduces the effectiveness of the protection you 
would otherwise receive.

3) Plug your modular cable into the jack on the Model 504 or 505.

If you have a Model 504, the cable must be terminated with an 
RJ-11 plug.  If you have a Model 505, the cable must be 
terminated with an RJ-45 plug.

4) To provide an alternate ground connection, use the short strap 

supplied with the unit.  Connect one loop to the device chassis 
(or other chassis ground) and the other loop to the Model 504 
or 505 as shown below.

1.1  RADIO AND TV INTERFERENCE

The Model 504 & 505 Series units generate and use radio

frequency energy, and if not installed and used properly—that is, in strict
accordance with the manufacturer's instructions—may cause
interference to radio and television reception.  They have been tested
and found to comply with the limits for a Class A computing device in
accordance with the specifications in Subpart J of Part 15 of FCC rules,
which are designed to provide reasonable protection from such
interference in a commercial installation.  However, there is no
guarantee that interference will not occur in a particular installation.  If
these products do cause interference to radio or television reception,
which can be determined by turning off the unit, the user is encouraged
to try to correct the interference by one or more of the following
measures:  moving the computing equipment away from the receiver, re-
orienting the receiving antenna and/or plugging the receiving equipment
into a different AC outlet (such that the computing equipment and
receiver are on different branches).

1.2  CE NOTICE

The CE symbol on your Patton Electronics equipment indicates that

it is in compliance with the Electromagnetic Compatibility (EMC)
directive and the Low Voltage Directive (LVD) of the Union European
(EU).  A Certificate of Compliance is available by contacting Technical
Support.
