THREE-PHASE NETWORK ANALYSER 90A

Read all the instructions carefully

The ADR-D 400 D90 network analyzer is a direct connection digital multimeter for

three-phase systems up to 90 A for true effective value measurements (TRMS). The

isolated RS-485 serial output allows, through the MODBUS protocol functions and

the use of the relative registers, to connect the analyzer to a Master device (PC/

PLC...) for data visualization and archiving.

SAFETY INSTRUCTIONS

During the installation and operation of the device, observe the following

instructions:

1) The device must be installed by a qualied person

2) The device must be installed in an electrical panel which, after installation,

leaves terminals inaccessible

3) The electrical system in the building where the device is installed must

feature a switch or circuit breaker: this must be near the device and in a

position that can be easily reached by operators

4) A protection device against over-currents must be installed in the electrical

system, upstream of the instrument

5) Connect the device as shown in the diagrams of this manual

6) Before making contact with terminals, ensure that conductors to be

connected to the device are not live

7) Do not power or connect the device if any part of it is damaged.

NOTE: Network analyzer ADR-D 400 D90 is aimed for use in places with over-

voltage category III and pollution degree, 2 as per EN 61010-1

INSTALLATION

WIRING DIAGRAM

LOAD

NOTE:

Connection of the neutral conductor may ONLY be omitted for balanced

symmetrical three-phase systems

INSTALLATION

Network analyzer ADR D 400 D90 may only be used in three-phase systems 230 Vac

Phase-neutral, with 400 Vac Phase-Phase voltage between lines.

For installation, follow the connection diagram shown above:

− for 4-wire three-phase systems (3 phases + neutral) also with non-symmetrical and/

or non-balanced systems, connect the neutral lead to terminal 1

− for 3-wire three-phase symmetrical and balanced systems, it is possible not to

connect the neutral lead

For correct measurement, the 3 phase leads coming from the distribution panel must

be inserted in the through holes vertically from above; failure to do so will cause a

connection-error warning to appear on the display. In case of a connection error, the

display will indicate which phase or phases are misconnected (cfr. “ERROR MESSAGES

– MISCONNECTION” ).
