D000030110 d – E650 Series 3 (ZMD400AT/CT, ZFD400AT/CT) – User Manual
The present user manual applies to the meters specified on the title page.
The user manual contains all the information required for application of the
meters for the intended purpose. This includes:

Provision of knowledge concerning characteristics, construction and
function of the meters

Information about possible dangers, their consequences and meas-
ures to prevent any danger

Details concerning the performance of all work throughout the service
life of the meters (parameterisation, installation, commissioning, op-
eration, maintenance, shutting down and disposal)
The contents of this user manual are intended for technically qualified per-
sonnel of utilities (energy supply companies) responsible for the system
planning, installation and commissioning, operation, maintenance, decom-
missioning and disposal of the meters.
The technical data and functional description of the meters are explained in
separate documents:



D000030112 "E650 ZxD Series 3 Functional Description"
The structure and significance of meter type designations are described in
section 1.3 "Type Designation". The following conventions are employed in
this user manual for representing type designations:

The lower case letter "x" can be used as an unknown to indicate dif-
ferent versions (e.g. ZxD400 for the ZMD400 and ZFD400 meters or
ZMD410xT for the ZMD410AT and ZMD410CT meters).

The digit pair "00" can be used to indicate accuracy data (e.g. ZxD400
for the ZxD405 and ZxD410 meters).

The abbreviated type designation ZMD or ZFD meters can be used
when all three-phase four-wire meters or three-phase three-wire me-
ters are meant.

The following collective terms are also sometimes used instead of the
type designation:
– "Active energy meters" for the ZxD400AT meters
– "Combimeters" for the ZxD400CT meters
