<strong>Installation</strong> <strong>RSU</strong>-<strong>503</strong> <strong>Redundancy</strong> <strong>Switch</strong> <strong>Unit</strong><br />
To install the switch to a round vertical pole:<br />
1. Set the switch on its side, with the mounting holes facing up.<br />
2. Install the 14” unistrut as follows:<br />
a. Position a 14” long<br />
unistrut (with the open<br />
side facing up) over<br />
the mounting holes on<br />
the unit.<br />
b. Using three 1/4-20 x<br />
5/8” bolts, 1/4” split<br />
lockwashers, and 1/4”<br />
flat washers, attach the<br />
unistrut to the switch.<br />
c. Tighten the bolts<br />
firmly.<br />
3. Install the pipe blocks as follows:<br />
a. Install two spring nuts in the 14” long unistrut which is mounted on the unit,<br />
and in a second 14” long unistrut.<br />
Be sure to center the spring nuts in the unistruts wide enough apart so that<br />
when the pipe blocks are installed, they will clear the pole when the unit is<br />
lifted into place for installation.<br />
b. Install each spring nut as follows:<br />
(1) Place the spring<br />
nut in the unistrut<br />
channel, spring<br />
side down, with<br />
its wide side<br />
parallel with the<br />
unistrut channel.<br />
