ELECTRICAL INSTALLATION
Do not install the unit close
to high electromagnetic
noise emitting devices like
contactors, high current
busbars, switchmode power
supplies and the like.
Although the unit is protected against
electromagnetic disturbance, excessive
disturbance can affect the operation and
measurement precision.
ALWAYS remove plug connectors when
inserting wires with a screwdriver.
Fuses must be connected to phase voltage
inputs, in close proximity of the unit. Fuses
must be of fast type (FF) with a maximum
rating of 6A.
Use cables of appropriate temperature
range and section, at least 0.75mm
(AWG18).
For current transformer inputs, use at least
2
1.5mm
section (AWG15) cable.
The current transformer cable length
should not exceed 1.5 meters. If longer
cable is used, increase the cable section.
5A Current transformers must be used.
Current Transformers must be
used for current measurement.
No direct connection allowed
Do not overload the relay
outputs. If necessary use

extra contactors.
