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).

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.
