2 - CONNECTION OF THE INSTRUMENT
2.1 -
POWER SUPPLY
The power supply connections terminals are located on the rear side and are clearly indicated with the label POWER
SUPPLY. Use cables having a maximum section of 2.5 mm
2
. Earth connection is not required. Follow the connection
diagram at the beginning of the manual.
2.2 -
CONNECTING VOLTAGE MEASUREMENT CABLES
These cables, having a maximum section of 2.5 mm
2
, are to be connected to the terminals labelled VOLTAGE INPUT as
indicated in the diagrams at the beginning of the manual.
2.3 -
CONNECTING CURRENT MEASUREMENT CABLE
The instrument is able to measure up to 5A only through external C.T. The cables having maximum section of 2.5 mm
2
must be connected to the terminals labelled CURRENT INPUT as shown in the diagrams at beginning of the manual.
Use Use 3 CT's with 5A secondary. Use cables having a section appropriate to the length of the connection and the rated
power of the CT's used.
Note 1: For safety reasons, never leave the CT secondary open.
Note 2: Important direct connections, without C.T. will damage the inputs.
3 - PROGRAMMING THE INSTRUMENT
The instrument can be fully programmed by means of the SETUP menu. Press at the same time the PAG and the SEL keys
to enter the SETUP . The complete description of the setup is available at chapter 5.
