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.
