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.
Follow national rules for electrical installation.
Current transformers must have 5A output.
