9.3.4 Connecting Alarm Output
The terminal blocks use M3.0 screws (at a tightening torque of 0.5 N•m).
We recommend that you use a round crimp connector (RAV 1.25-
3) for connection.
Open collector output (Rating: 30 VDC, 20 mA max.)
Design the wiring to prevent short-circuiting of the ALARM
and CLAMP SENSOR INPUT terminals, thus avoiding electric
shock and accidents due to short-circuiting.
• The ALARM terminals are electrically insulated from the U
INPUT terminals and CLAMP SENSOR INPUT terminals.
• To avoid the effects of external noise, design the wiring so that
cables connected to the ALARM terminals are separated from
those for measurement, as well as cables connected to the
CLAMP SENSOR INPUT terminals and voltage cables.
