mProduct Description
Ordering Key
oµP-based energy meter with
a built-in configuration key-
.cpad. The energies are both
partial and total counted. The
housing is easy to mount on
DIN-rail and ensures a
degree of protection (front) of
IP 40.

1. Key-pad
Set-up and programming procedures are easily controlled
by the 4 pushbuttons.
” ” and ” ”
- To scroll all the basic measurements (system variables)
- To increase or decrease programming values
- To enter into the programming procedure and select
programming functions together with the ”L” key
“L”: To select the partial or total counted energy
“R”: To reset the partial counted energies (kWh, kVArh).
2. Display
- 6-digit (maximum read-out 999999).
Alphanumeric indication by means of LCD display for:
- Displaying the configuration parameters
- All the measured variables.
3. Connection terminal blocks
4. Dip-switch
- For the selection of 2/4 wire connection, line biasing
and/or line termination (only in case of RS 485 option)
