Notes:
1. Coil resistance varies ±10% for less
than 1,000 W, and ±15% for more than
1,000 Ω. For each ±1°C change in ambient temperature, coil resistance varies
±
0.4%.
2. For each ±1°C change in ambient temperature, pick-up and drop-out voltages
vary approximately ±0.4%.
3. Pic k-up and drop-out voltages are measured with the relay mounted as follows.
4. The coil operating current should be
pure direct current in principle. When rectified alternating current is applied to the
coil, the relay characteristics (pick-up,
drop-out voltage) may be changed due to
the ripple factor. Confirmation of the characteristics in the actual circuit is suggested.

NOTES
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 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 remo v e
a receptacle, 2 to 4 kg of pulling strength
is required. Do not remo ve more than one
receptacle at one time.Always remove
one receptacle at a time and pull it straight
outwards.
5. Install the rela y 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. Theref ore, 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. Since the JH rela y latching model is polarized, be sure to follow the instructions
in the wiring diagrams when wiring the +
and - coils. Mistaken wiring will lead to incorrect operation and failures. Short the
negative side no. 6 and no . 8 set and reset
terminals.
8. When using the push-on blocks for the
screw terminal type, use crimped terminals and tighten the screw-down terminals to the torque listed below.
M4.5 screw
147 N·cm to 166.6 N·cm
(15 to 17kg·cm)
M4 screw
117.6 N·cm to 137 N·cm

NOTES
1. Be careful not to drop the relay. It is
made of heat-hardened resin and may
break.
2. Be sure to tighten the screw-down terminals firmly . Loose terminals may lead to
the generation of heat.
