Patton electronic MODEL 552 - Manual (Page 6)

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.
