Safety Precautions (Common)
Refer to Safety Precautions for All Counters.
Note: The following precautions are common for all H7CX models.
■ Precautions for Safe Use
Operating and Storage Conditions
• Do not use in locations affected by excessive vibration or shock, or
• Do not use the product in locations subject to dust, corrosive
• Separate the input signal devices, input signal cables, and the
• Separate the product from the source of static electricity when
• Organic solvents (such as paint thinner), as well as very acidic or
• Use the product within the ratings specified for temperature and
• Do not use the product in locations where condensation may occur
• Store at the specified temperature. If the H7CX has been stored at
Usage Precautions
• Make sure that the voltage applied is within the specified range,
• The load current must be within the rated current.
• Ensure that the power is turned OFF before changing DIP switch
• Pay attention to terminal polarity to ensure correct wiring.
• Make sure that the fluctuation of the supply voltage is within the
• Apply the power supply voltage through a relay or switch in such a
• Set each set value to match the item being counted (or measured).
• Leaving the H7CX with outputs ON at a high temperature for a long
Loose screws may occasionally result in fire or malfunction.
Tighten the terminal screws securely. The recommended
tightening torque is 0.5 N·m.
There may occasionally be a risk of explosion. Do not use the
product where flammable or combustion gases are present.
If the output relay is used beyond its life expectancy, its contacts
may occasionally become fused or there may occasionally be a risk
of fire. 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.
This may occasionally cause electric shock, fire or malfunction.
Never disassemble, repair or modify the product.
This may occasionally cause electric shock, fire or malfunction.
Do not allow metal fragments or lead wire scraps to fall inside this

way that the voltage reaches the rated value within 2 s. If the
voltage is applied gradually, the power may not be reset or unstable
output operations may result.
Not matching the content of the set values with the counted (or
measured) items may cause unexpected operations resulting in
injury or damage to the equipment.
time may hasten the degradation of internal parts (such as
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.
CAUTION
• When the product is operated with no-voltage input (NPN input),
• Install a switch or circuit-breaker that allows the operator to
