NB:
This method offers several connection
possibilities for current and voltage.
Cables can be passed through the
device for the current, whilst other
cables can be used for the voltage
connected to their respective terminals.
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.
COUNT 063B GB
The Countis ATd has two connection
modes for current and voltage.
Remove the two covers to access the
terminals.

ELECTRICAL CONNECTIONS
• Single-phase (1 BL):
- Current measurement:
Pass cable through I1 and IN.
- Voltage measurement:
Perforate cable insulation for cable
passing through I1 and IN, or
connect V1 and VN.
NB: It is imperative to use cable with
a maximum section of 2.5mm
2
bet-
ween terminals V2 and VN.
•
Two-phase (2BL):
- Current measurement:
Pass cable through I1 and I2.
- Voltage measurement:
Perforate cable insulation for cable
passing through I1 and I2, or
connect V1 and V2.
•
Three-phase (balanced) with or
without neutral (3 or 4 BL)
- Current measurement:
Pass cable through 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:
Pass cables through I1, I2, I3 and
IN (if neutral is distributed).
- Voltage measurement:
Perforate cable insulation for
cables passing through I1, I2, I3
and IN (if neutral is distributed),
or connect V1, V2, V3 and VN
(if neutral is distributed).
