ELECTRICAL CONNECTIONS

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 termi-
nals.
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.

The Countis ATd has two connection
modes for current and voltage.
TERMINAL-FREE CONNECTION
Remove the two covers to access the
terminals.

• 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
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
2 bet- 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).
