Mounting the Enclosure
Figure 2
Custom Panel
or Electrical Box
Wall or Panel Door
To mount the wiring enclosure:
Remove the front cover of the enclosure by removing the
two screws in the cover.
Place the enclosure in the location decided upon during
the rough-in wiring stage. Wiring will enter through either
the top and bottom knockouts or through the back upper
and lower knockouts. See figures 1 and 2.
There are twelve holes in the back of the enclosure that
allow for mounting.
•
•
Using screws, ensure that the enclosure is securely
fastened in place.
Note: The nonmetallic conduit entries in the back of the
enclosure do not provide grounding between conduit
connections. Use bonding bushings and jumpers to provide
a continuous path to ground.

Electrical Drawings
The electrical drawing examples on the following pages
show the 346 in common applications. These drawings
have a brief explanation of what is being operated in each
system. Choose the components in your system and use
the drawings as a guide to aid in wiring your system.
These are only concept drawings, not engineered drawings.
They are not intended to describe a complete system nor
any particular system. It is up to the system designer to
determine the necessary components for and configura-
tion of the particular system being designed including
additional equipment isolation relays (for loads greater
than the controls specified output ratings) and any safety
devices which in the judgement of the designer are ap-
propriate in order to properly size, configure and design
that system and to ensure compliance with building and
safety code requirements.
