205-TC Datasheet, PDF (22/22 Pages) List of Unclassifed Manufacturers – THERMOCOUPLE MINIATURE PANEL THERMOMETER

3.7 Main Power Connections
Connect the ac main power connections as shown below.
WARNING: Do not connect ac power to your meter until
you have completed all input and output connections.
Failure to do so may result in injury! This device must
only be installed electrically by specially trained
electrician with corresponding qualifications. The main
power input to the unit as well as the AC input signal to be
measured must agree with the wiring instruction.
The meter is factory set to the power specified by the
customer at the time of ordering. The voltage is printed on the
Label under Input power.
Refer to Section 3-2 to convert from one configuration
to another.
To connect power to the unit, attach wires from the ~AC power
cord to the orange 3-pin female connector that is supplied with
the meter. Refer to Figure 3-7 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.

DC WIRING
The meter can be configured at the factory to operate on a
9–26 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 9–26 Vdc –DC
Return (P1-1), therefore, it is recommended that an
ungrounded thermocouple probe be used to prevent
ground problems.
