Follow 3-5 Terminal Layout and 3-6 Terminal Arrangement
Table and make sure to conduct wiring correctly.
The press-fit terminal must fit an M3.5 screw and have a
width of 7 mm or smaller.
The input signal wire must not be accommodated with a
high-voltage power cable in the same wiring conduit or duct.
Shielded wire (one-point grounding) is effective to avoid
electrostatic induction noise.
Twisting the input wires at short and equal intervals is an
effective way to avoid magnetic induction noise.
For wiring for power supply, use a 600V vinyl insulated wire
or cable which is 1 mm2 or larger in section or a wire or cable
of equivalent for higher performance.
The wire for grounding must be 2 mm2 or larger in section
and must be grounded at a grounding resistance of 100
ȍ
or
lower.
Clamp the terminal screws firmly.
Clamp receiving torque: 1.0N.m (10 kgf.cm)

against lightning surge will be required for
signal line over 30m.
Cut a hole for mounting the controller in the panel by
referring to the cutout drawing in Section 3-4.
The panel thickness should be 1.0 ~ 4.0 mm.
As the instrument is provided with pawls for fixing, just press
it firmly from the front of the panel.
The EM70 is designed to be mounted on a panel. Never use it
without mounting on the panel.
Be sure to install this product with the attached gasket.
Failure to do so could result in electric shock.
