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.
