Be sure to read the precautions for all Counters.

Warning Indications

Meaning of Product Safety Symbols

Do not allow pieces of metal, wire clippings, or fine

metallic shavings or fillings from installation to enter

the product. Doing so may occasionally result in

electric shock, fire, or malfunction.

Minor injury due to explosion may occasionally occur.

Do not use the Counter where subject to flammable or

explosive gas.

Fire may occasionally occur. Tighten the terminal

screws to the rated torque.

H7CC terminals and

P3GA-11/P3G-08 socket terminals

: 6.55 to 7.97 lb-in (0.74 to 0.90 N·m)

P2CF Socket terminals: 4.4 lb-in (0.5 N·m)

Minor injury due to electric shock may occasionally

occur. Do not touch any of the terminals while power

is being supplied. Be sure to mount the terminal cover

after wiring.

The service life of the output relay varies considerably

according to its usage. Use the output relay within its

rated load and electrical life expectancy. If the output

relay is used beyond its life expectancy, its contacts

may become fused or there may be a risk of fire. Also,

be sure that the load current does not exceed the

rated load current and when using a heater, be sure to

use a thermal switch in the load circuit.

Minor electric shock, fire, or malfunction may

occasionally occur. Do not disassemble, modify, or

repair the Counter or touch internal components.
