E5CN


WIRING TERMINALS

The voltage output (control output) is not electrically insulated
from the internal circuits. When using a grounding thermocouple,
do not connect the control output terminals to the ground. If the
control output terminals are connected to the ground, errors will
occur in the measured temperature values as a result of leakage
current.

Two input power supplies are available: 100 to 240 VAC or 24 VDC.

WIRING PRECAUTIONS

Separate input leads and power lines to protect the E5CN and its lines from external noise.
We recommend using solderless terminals when wiring the E5CN.
Tighten the terminal screws using a torque no greater than 0.78 N
Use the following type of solderless terminals for M3.5 screws.
7.2 mm max.
7.2 mm max.
Standard insulation is applied to the power supply I/O sections.
If reinforced insulation is required, connect the input and output
terminals to a device without any exposed current-carrying parts
or to a device with standard insulation suitable for the maximum
operating voltage of the power supply I/O section.
