Although the unit is protected against
electromagnetic disturbance, excessive
disturbance can affect the operation,
measurement precision and data
communication quality.
Use cables of appropriate temperature
range.
Use adequate cable section, at least
0.75mm
2
(AWG18).
For current transformer inputs, use at
least 1.5mm
2
section (AWG15) cable.
The current transformer cable length
should not exceed 1.5 meters. If longer
cable is used, increase the cable
section proportionally.
Current transformers must have 5A
output.
For the RS-485 connection, use
appropriate shielded twisted wire
cable. Communication quality will
depend highly on the cable used.
Do not install the unit close
to high electromagnetic
noise emitting devices like
contactors, high current
busbars, switchmode power
supplies and the like.
