Recommendation:
Cables should follow the direction
indicated by the arrows on the enclo-
sure.
The use of 500 mA gG fuses is
recommended for voltage input pro-
tection when using specific cable for
voltage.

• Single-phase (1 BL):
- Current measurement:
Connect top and bottom of I1.
- Voltage measurement:
Connect terminals V1 and VN.
NB: It is imperative to use cable with
a maximum section of 2.5mm
ween terminals V2 and VN.
• Two-phase (2BL):
- Current measurement:
Connect top and bottom of I1
and I2.
- Voltage measurement:
Connect terminals V1 and V2.
For optimal operation use cable
connections with the following
sections:
PULSE OUTPUT
A reed relay (100 V - 0,5 A - 10 VA)
available on the Countis ATd provides
a pulse for active energy, the value
being fixed at 100 Wh. The duration
can be programmed (see § program-
ming).

• Three-phase (balanced) with or
without neutral (3 or 4 BL):
- Current measurement:
Connect top and bottom of I1.
- Voltage measurement:
Connect V1, V2, V3 and VN (if
neutral is distributed).
