The Patton Model 535 and 536 are very easy to install: no special
cables or batteries are needed. Simply unplug the cable from the AUI
port and insert the unit between the cable and the port as shown in the
appropriate diagram below.
If you are installing the Model 536, you will also need to
connect the braided ground strap. Connect this strap directly to a
frame ground connection on the protected device. If you are unsure
where to locate a frame ground on your equipment, consult the
equipment's user manual or contact the manufacturer—the ground
connection is critical for proper operation of the Model 536.
Note: The Model 535 shunts surge current to chassis ground
through the connector shells on both ends. If you have any questions
as to whether your hardware is grounded properly, consult the
manufacturer's user manual(s).
