The electrical drawing examples on the following
pages show the 482 in common applications. These
drawings have a brief explanation of what is being operat-
ed in each system. Choose the components in your sys-
tem 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 configuration 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 judgment of the designer are
appropriate in order to properly size, configure and design
that system and to ensure compliance with building and
safety code requirements.
The control can be mounted on a
standard DIN rail. First remove the
control from its base and then,
using the hooks and spring clip
on the back of the control, mount
it onto the DIN rail. This will be a
popular option for those who pre-
fer to mount the control inside a
larger electrical panel.
The wiring can enter the bottom
or the back of the enclosure.
Knock-outs provided in the base
allow the wiring to be run in
conduit up to the enclosure. The
base also has holes that line up
with the mounting holes of most
common electrical boxes.
Press down at the fingertip grips
on top of the front cover and pull
out and down.
Lift the front cover up and away
from the control.
Loosen the screws at the front
of the wiring cover.
The wiring cover pulls straight out
from the wiring chamber.
The base is ready for mounting.
The control lifts up and away
from the base.
Press the control release clip
on the base inside the wiring
chamber and slide the control
upwards.
Remove the safety dividers
from the wiring chamber by
pulling them straight out of
their grooves.
There are 10 conduit knock-outs at the
back and bottom of the wiring chamber.
