DC WIRING
The meter can be configured at the factory to operate on a
9Ð26 VDC non-isolated power. The DC voltage option is
specified at the time of ordering. See
Table 1-3
for model
number listing. An AC powered meter cannot be converted to
a DC powered meter or vice versa.
To connect power to the unit, attach the DC power wires to the
orange 3-pin female connector that is supplied with the meter.
Refer to
Figure 3-8
for wiring instructions. Plug the female
connector into the orange P1 (male) connector at the rear of the
meter.
Figure 2-2
shows the location of P1 on the meter.
-TC input (P3-1) is internally connected to 9Ð26Vdc ÐDC
Return (P1-1), therefore, it is recommended that an
ungrounded thermocouple probe be used to prevent
ground problems.
