INPUT POWER
The AC Input power routing and connections to the
control panel should be supplied from a FUSED
DISCONNECT rated 10 Amps/240VAC or great-
er, and should meet all guidelines of applicable
electrical codes and any other requirements as
suitable for the location. LOCKOUT/TAGOUT
procedures should be put in place for the fused
disconnect. Using conduit, route the input power
wiring, 14 AWG (2mm 2 / 300V minimum) through
Temperature/Humidity Probe(s)
(Optional) the AC Power opening in the top left corner of the
control panel. For greatest noise immunity the AC
input should be located as close as possible to the
AC line filter (see Figure 4). For this reason it is
recommended that the AC input not be relocated
to another position on the control panel. Route
the input power wiring through the conduit and
attach to terminal block TB3 as shown in Table 1
and Figure 4.
>
After making the input power con-
nections, double-check to ensure that
the control panel is properly grounded by
measuring the resistance from one of the
Remote I/O connectors on the top of the
panel to an external ground reference.
The resistance should be less than 0.1
ohms.

The temperature/humidity probes MUST
be located outside the hazardous area (see
NFPA-33).

!
Install the optional temperature/humidity probe(s)
in a desired area outside the hazardous location
such that the maximum length of cable from the
probe to the control panel does not exceed 250
ft. (76.2m). A 50 ft. (15.2m) cable assembly
is supplied with each probe. Additional 50 ft.
(15.2m) cable assemblies (p/n 77220-00) may be
purchased separately to extend this length up to
the 250 ft. (76.2m) maximum.
