Wiring the Wall-Mount
(cont.)
All connections to the wall-mount unit are made through the panel at
the bottom of the case as shown in Figure 2-6 below. Any I/O cabling
is brought into the unit through glands at the lower right of the case
and connects to the terminal blocks inside the case. Wiring for these
connections is shown below and in Figure 2-8 on page 2-7. The dew
point sensor and temperature sensor cable connectors are located on
the black mounting block.
IMPORTANT:
AC and signal wiring must be done in accordance
with local codes. Wire size cannot exceed 14 AWG
(2.08 mm

). Insulation shall be stripped 6 mm prior
to being inserted into the connection block.
