Note: In no circumstance should the secondary of the PT be shorted. The secondary of the

PT should be grounded at one end. Please refer to the wiring diagram section for further

details.

Current Input:

Current Transformers (CTs) are required in most engineering applications. Typical

current rating for the secondary side of the CT shall be 5A (standard) or 1A (Optional),

please refer to the ordering information appendix for further details. CTs must be used

if the system rated current is over 5A. The accuracy of the CT should be better than 0.5%

with rating over 3VA is recommended in order to preserve the meter's accuracy. The wire

between CTs and the meter shall be as short as possible. The length of the wire have an

eect on the accuracy.The wire size of current input is AWG15-10 or 1.5-2.5mm2.

Note: The secondary side of the CT should not be open circuit in any circumstance when

the power is on. There should not be any fuse or switch in the CT loop. One end of the CT

loop should be connected to the ground.

Vn Connection:

Vn is the reference point of the Acuvim II series meter voltage input. Low wire

resistance helps improve the measurement accuracy. Different system wiring modes

require dierent Vn connection methods. Please refer to the wiring diagram section for

more details.
