Installation
Figure 3-30: Potting Conduits
1
Mix compound in a clean vessel according to compound manufacturer’s directions. Mix only
as much potting compound as can be used before compound hardens. Refer to compound
manufacturer’s instructions.
2
Using a funnel, carefully pour sealing compound into conduit from top until compound is
within 1/4-inch of top of conduit. See
Figure 3-30 .
Note: Be sure to pour slowly so as to prevent air bubbles from forming in compound and
around wires.
3
Immediately clean all spilled compound from conduit threads and cabinet surfaces.
4
Install UL Listed metallic conduit capped bushing.
Completing Field Wiring
Field power connections in some older contractor supplied box or without a junction box,
wiring is connected to WAGO spring-loaded terminals in the electronic cabinet. Newer units
are wired using wire nuts. For WAGO Terminal equipped units the use of the WAGO tool (see
“Required Equipment and Materials” on page 11 ) is highly recommended. If the tool is not
available, a small insulated shank screwdriver may be used to open the spring-loaded terminal
by pressing down on the spring through the slot provided, but care must be exercised to
prevent damage.
Fuels vapors allowed to travel
between the hydraulics and
electronics cabinets presents
the risk of fire or explosion.
Resulting fire or explosion
may lead to serious injury or
death.
Never compromise the vapor
barrier integrity by leaving out
conduit plates or in any way
leaving open holes, for
example; using conduit smaller
than 1'' diameter. For Canadian
applications do not leave out
any gaskets.
Listed metallic conduit nut
must be installed at top of 8''
conduit for mechanical
retention of potting in the
event of explosion.
