MOUNTING METHOD
1. Plug-in terminal type
M4 screw
Washer
Faston No.250
2. Screw terminal type
M 4 screw
Washer
3. Allowable installation wiring size for
screw terminal types and terminal blocks
1a type
2a type
2.6 mm or 5.5 mm
2
2.0 mm or 3.5 mm

Due to the UP terminals, it is possible to
either directly connect the wires or use
crimped terminal
NOTES
1. The dust cover should not be removed
since doing so may alter the characteris-
tics.
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 5
kg to 7 kg·cm
4.5 to 6 pounds·inch.
4. Firmly insert the receptacles so that
there is no slack or looseness. To remove
a receptacle, 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. Install the relay so that it lies in direction
A (up-down direction). (Pick-up voltage
and drop-out voltage values are those
when installed in direction A.)
6. 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. Moreover, the release time for the
NC side of the 2a1b type requires the
same verification.
7. When using the push-on blocks for the
screw terminal type, use crimped termi-
nals and tighten the screw-down termi-
nals to the torque’s listed below.
M4.5 screw
M4 screw
M3.5 screw
147 N-cm to 166.6 N-cm
(15 to 17 kg·cm)
117.6 N-cm to 137 N-cm
(12 to 14 kg·cm)
78.4 N-m to 98 N-cm
(8 to 10 kg·cm)
8. All AC240V types are rated for double
coil voltage, both AC 220V AC 240V.
For Cautions for Use, see Relay Technical Information (Page 11 to 39).
