Reference Information
2
Run field wiring through a 1-inch trade size conduit stub up centered in the rectangular
opening.
3
Stub up must be inside the column and centered in the column as closely as possible.
There is very little extra room with 1-inch fittings. See
Figure 4-7 .
Note: If stub up is not properly located in the column, it will interfere with the column outer
sheathing.
4
Use a 1-inch trade size conduit stub up long enough to extend at least 1-inch above the lower
edge of the rectangular opening.
5
Thread end of stub up using a 1-inch NPT (tapered threads) in order to use a sealing fitting. It
is recommended that the installer uses a Killark EY-3 or Killark ENY-3. These fittings are
compact and will fit inside the column. See
Figure 4-8 .

6 Install sealing fitting to stub up. Tighten all fittings (minimum 5 full threads of engagement).
7 Pull wiring through the stub up and sealing fitting.
Note: Make sure enough extra wire length (minimum of 5 feet or 2 meters) is provided in order to
make the run to the stub up location at the bottom of the electronics cabinet.
Note: Remember you may be routing the conduit over to come up at the stub up to the electronic
cabinet. Depending on which end of the unit the stub up is on, you may be
routing across
the entire unit length.
8
Fill sealing fitting with potting compound to seal the pathway of the field wiring. See “Sealing
Air Gaps and Conduits in Encore Units” on page 42 or “Potting Conduit Stubs” on page 44.
9
Install a short 2-inch threaded nipple into the top of the sealing fitting.
