Safety Precautions
Refer to Safety Precautions for All Counters.
Tighten the terminal screws to the specified torque (approx. 0.5 N⋅m).
Fire or malfunction may result if the screws become loose.
Do not use the product in locations subject to flammable or explosive
gases. Doing so may result in explosion.
The service life of the output relays depends on the switching capacity
and switching conditions. Consider the actual application conditions
and use the product within the rated load and electrical service life.
Using the product beyond its service life may result in contact
deposition or burning.
Do not disassemble, repair, or modify the product. Doing so may
result in electric shock, fire, or malfunction.
Do not allow metal objects or conductive wires to enter the product.
Doing so may result in electric shock, fire, or malfunction.
Other Precautions
• Store at the specified temperature. If the H8GN has been stored at

electrolytic capacitors). Therefore, use the product in combination
with relays and avoid leaving the product as long as more than 1
month with the output turned ON.

insert the adapter from the back, and
push the H8GN into the cutout as far
as possible. Use screws to secure the
H8GN. To make the H8GN waterproof,
insert waterproof packing and tighten
the screws.
