Connections to a 24 VAC Power Supply
Separate floating supply for each transmitter is recommended (see the
upper part of Figure 27 on page 44). If you have to connect several
transmitters or other instruments to one AC supply, the phase (~) must
always be connected to the (+) connector of each transmitter (see the
lower part of Figure 27).
CAUTION
24
VAC POWER SUPPLY USE
To prevent fire and/or damage, if either 24
VAC wire is grounded or
connected to a "
-", "0", or "GND" terminal of any other device, you
must connect the same wire on the "
-" terminal also on this instrument.
