External hinged current transformers
Ensure that the current transformers are assigned correctly (
I1
to
L1
,
I2
to
L2
and
I3
to
L3
) and that
the energy direction is observed.
PLEASE NOTE:
Before snapping the current transformer onto the phase conductors, they must al
-
ready be connected to the CAN-EZ3. Otherwise the current transformers can be damaged.
Each external current transformer is labelled with "
K
L
", whereby the
energy direction must be
from K to L
for positive metering.
The poles of the cable connecting the electricity sensor and the energy meter must not be swapped.
The white cable must be on the left and the black cable on the right.
Each current transformer must be closed carefully by clicking the snap fastener securely into place.
If the energy direction is changed, the energy meter counts in the negative.
