1. Plug-in type 2. Screw terminal type 3. Allowable installation wiring size for
screw terminal types and terminal
sockets
Due to the UP terminals, it is possible to
either directly connect the wires or use
crimped terminal.

1. The dust cover should not be removed
since doing so may alter the
characteristics.
2. Avoid use under severe environmental
conditions, such as high humidity, organic
gas or in dust, oily locations and locations
subjected to extremely frequent shock or
vibrations.
3. When mounting, use spring washers.
Optimum fastening torque ranges from
49 to 68.6 N⋅m (5 to 7 kgf·cm).
4. Firmly insert the receptacles so that
there is no slack or looseness. To remove
a receptacle, 19.6 to 39.2 N (2 to 4 kg) of
pulling strength is required. Do not
remove more than one receptacle at one
time. Always remove one receptacle at a
time and pull it straight outwards.
5. When using the AC type, the operate
time due to the in-rush phase is 20 ms or
more. Therefore, it is necessary for you to
verify the characteristics for your actual
circuit.
6. When using the push-on blocks for the
screw terminal type, use crimped
terminals and tighten the screw-down
terminals to the torque below.
M4.5 screw:
147 to 166.6 N⋅cm (15 to 17 kgf·cm)
M4 screw:
117.6 to 137 N·cm (12 to 14 kgf·cm)
M3.5 screw:
78.4 to 98 N·cm (8 to 10 kgf·cm)
