Safety Precautions for All H7CX Series (Common)
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.
H7CX 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 life expectancy 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.

internal circuits from water penetration through the space between
the H7CX and operating panel, waterproof packing is included.
