This section describes the appearance, layout and function of all operating
elements and displays of the ZxD400xT meters as well as operating
sequences.
Illustrations
The illustrations of the faceplate and display in this section always show the
ZxD400CT combimeter (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:
