Connections to a 24 VAC Power Supply
Separate floating supply for each transmitter is recommended (see the
upper part of Figure 18 on page 34). 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 18).

connected to a "
