I Operating Environment

• Use the product within the ratings specified for submerging in water

and exposure to oil.

• Do not use the product in locations subject to vibrations or shocks.

Using the product in such locations over a long period may result in

damage due to stress.

• Do not use the product in locations subject to dust, corrosive

gases, or direct sunlight.

• Separate the input signal devices, input signal cables, and the

product from the source of noise or high-tension cables producing

noise.

• Separate the product from the source of static electricity when

using the product in an environment where a large amount of static

electricity is produced (e.g., forming compounds, powders, or fluid

materials being transported by pipe).

• Organic solvents (such as paint thinner), as well as very acidic or

basic solutions might damage the outer casing of the H7CX.

• Use the product within the ratings specified for temperature and

humidity.

• Do not use the product in locations where condensation may occur

due to high humidity or where temperature changes are severe.

• Store at the specified temperature. If the H7CX has been stored at

a temperature of less than -10

°C, allow the H7CX to stand at room

temperature for at least 3 hours before use.

• Leaving the H7CX with outputs ON at a high temperature for a long

time may hasten the degradation of internal parts (such as electro-

lytic 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.

• The load current must be within the rated current.

I Insulation

• Specifications call for basic insulation between the power supply

and input terminals, between the power supply and output termi-

nals, and between the input and output terminals. (The H7CX-A

is not insulated between the power supply and input terminals.)

• Input and output terminals are connected to devices without

exposed charged parts.

• Input and output terminals are connected to devices with basic

insulation that is suitable for the maximum operating voltage.
