This section describes the location and function of all operating elements
and displays of the E650 ZMD300xT meters as well as operating sequences.
Illustrations
The illustrations of the faceplate and display in this section always show the
ZMD300CT combi-meter (with additional optical test output for reactive
energy, together with direction of reactive power and quadrant display).
Meters equipped with an auxiliary power supply which is supplied with
electricity (see section 3.4 "Connection diagrams (examples)") are
completely functional even in case of a power cut. Despite missing voltage
at the terminals they can be read out via display, remote readout, etc. and
parameterised, if desired.
Connect the auxiliary power supply as follows:
