For optimal operation use cable
connections with the following
sections:
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).

Recommendation:
Cables should follow the direction
indicated by the arrows on the enclo-
sure.
The use of 500 mA gG (or BS 88 2A gG)
fuses is recommended for voltage
input protection 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

•
Two-phase (2BL):
- Current measurement:
Connect top and bottom of I1
and I2.
- Voltage measurement:
Connect terminals V1 and V2.
•
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).
•
Three-phase (unbalanced) with
or without neutral (3 or 4 NBL):
- Current measurement:
Connect top and bottom of I1, I2,
I3 and IN (if neutral is distributed).
- Voltage measurement:
