Control Panel Internally
mounted devices
For visual identification Internal
Control Panel mounted devices are
identified by their respective
schematic designation number.
Control panel items are marked on
the inner back panel in the control
panel. Figure 7 illustrated below,
identifies these devices. The Control
Panel Devices table corresponds to
the same device designators (see
right hand column). Optional
controls are present when a specific
optional controls package is
specified, as listed in the second
column.
Figure 7. Standard Enclosure
Note: UCP control wiring (120 VAC) must not be routed with low voltage circuits (less than 30 VAC). Conduit
access holes are furnished in the top of the unit control panel. Use the left holes for low voltage wiring, and
use center and right hand holes for control (120 VAC) wiring.
Note: The wire is retained in the clamp by the force of the spring which pushes the wire against the
connecting bar. Use care to ensure full insertion of screwdriver into terminal block wire release mechanism.
Proper tool engagement is required to release the tension for wire insertion.
