CONNECTORS
To perform wiring connections, remove the
terminal block from the meter’s connector, strip
the wire leaving from 7 to 10mm exposed and
insert it into the proper terminal while pushing
the fingertip down to open the clip inside the
connector as shown in the figure.
Proceed in the same manner with all pins and plug the terminal block
back to the corresponding meter’s connector.
Each terminal can admit wires of section between 0.08 mm² and 2.5
mm² (AWG 26 ÷ 14).
Some terminals have removable adaptors to provide proper fastening for
wires of sections less than 0.5 mm².

INSTALLATION
To meet the requirements of the directive EN61010-1, where the unit
is permanently connected to the mains supply it is obligatory to install
a circuit breaking device easy reachable to the operator and clearly
marked as the disconnect device.
WARNING
In order to guarantee the electromagnetic compatibility, the following
guidelines should be kept in mind :
- Power supply wires may be routed separated from signal wires.
Never run power and signal wires in the same conduit.
-
Use shielded cable for signal wiring and connect the shield to the
ground of the indicator (pin2 CN1).
-
The cables section should be
≥
0.25 mm
2
If not installed and used in accordance with these
instructions, protection against hazards may be impaired.
2.8 – Programming lockout
After completing the instrument’s programming, it is
recommended to lockout the access to the programming to
prevent from accidental or unauthorized modifications.
This operation is made by taking off a plug-in jumper located
on the main board circuit (see figure at right).
NOTE : Disconnect power before changing
the jumper position.
While the instrument is locked out it is however possible to
acceed to the programming routines to check the current
configuration, but it won’t be possible to entry or modify data.
In this case, a push of
ENTER
to acceed the programming
routines will show the indication dAtA instead of Pro.

lock out the programming
