Warning! Risk of hazardous voltage

When operating the transducer, certain parts

may carry hazardous live voltage (e.g., primary

conductor, secondary terminals). The transducer

should not be put into service if the installation is

not complete.

Warning! Risk of electric shock or

personal injury

Safe operation can only be guaranteed if

the

is used for the purpose for

transducer

which it was designed and within the limits

of the technical specifications. When this

symbol is used, it means you should consult

all documentation to understand the nature

of potential hazards and the action required

to avoid them.

INSTALLATION

INSTRUCTIONS

Part No. 3ACT030-42-24-F

Quick Start Guide

1. Mount the 3ACT/3ACTR Current Transducer to a

DIN rail or panel in a suitable enclosure.

2. With monitored load off, install each phase

through the sensing windows. Designate one

phase as A, B, and C.

3. Select the current range using the slide

switch

4. Connect output terminals + and - using 22-14

AWG copper wires rated 75/90°C. Tighten to 5-7

inch-pounds torque.

5. Connect power supply voltage to terminals 9-10.

6. The output will be proportional to the current in

each phase, plus one which is the average of the

three.

7. Any of the four analog signals can be used

independently, or all four can be used at the same

time.
