H7CX
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 produc-
ing 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 oc-
cur due to high humidity or where temperature changes are se-
vere.
• Store at the specified temperature. If the H7CX has been stored
at a temperature of less than –10
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
electrolytic capacitors). Therefore, use the product in combina-
tion 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.
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@D is not insulated between the power supply and input termi-
nals.)
• Input and output terminals are connected to devices without ex-
posed charged parts.
• Input and output terminals are connected to devices with basic
insulation that is suitable for the maximum operating voltage.
