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, measurement precision and

data communication quality.

 Use cables of appropriate temperature range.

 Use adequate cable section, at least 0.75mm

(AWG18).

 For current transformer inputs, use at least

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 proportionally.

 Current transformers must have 5A output.

Current Transformers must be

used for current measurement.

No direct connection allowed
