There are two holes for each terminal. The hole on the right is the operating
hole; the hole on the left is the wire hole.
Insert a flat-blade screwdriver with a width of 2.5 mm into the operating hole
and then insert the wiring into the wire hole.
The wire will be clamped when the screwdriver is removed.
A1
Use crimp terminals for wiring that match the cross-sectional area of the
A2
wiring material.
A3
We recommend the following crimp terminals:

• 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.
• Conforming to Safety Standards
The power supply terminals must be supplied from a SELV, limited-current
source. A SELV (separated extra-low voltage) source is a power supply
having double or reinforced insulation between the primary and the sec-
ondary circuits and having an output voltage of 30 V r.m.s. max. and 42.4
V peak max. or 60 VDC max.
Recommended power supply: S8VM Series or S8VS Series (both manu-
factured by OMRON)
Note Select a power supply that suits the operating environment.
• To comply with the standards for noise terminal voltage for class A in EN
61326, install a noise filter (Densei Lambda MXB-1206-33 or the equiva-
lent) to the DC line as close as possible to the EJ1.
