Safety Precautions
Minor injury due to electric shock may occasionally
occur. Do not touch any of the terminals while
power is being supplied.
Fire may occasionally occur. Tighten the terminal
screws to a torque of 0.5 to 0.6 N·m (4.4 to 5.3 in-lb).
Minor injury due to explosion may occasionally
occur. Do not use the H7BX where subject to
flammable or explosive gas.
If the output relay is used beyond its life
expectancy, its contacts may become fused or
there may be a risk of fire.
Use the output relay within its rated load and
electrical life expectancy. The life expectancy of the
output relay varies considerably according to its
usage.
Minor electric shock, fire, or malfunction may
occasionally occur. Never attempt to disassemble,
modify, or repair the H7BX or touch any of the
internal parts.
● Operating Environment
● Power Supply
The H7BX is intended for indoor use only. Do not use the
H7BX outdoors or in any of the following locations.
This is a class A product (for industrial environments). In
residential areas, it may cause radio interference, in which
case the user may be required to take adequate measures to
reduce interference.
Use the H7BX within the specified ratings for operating
temperature and humidity. Temperature rise may shorten the
service life of H7BX if it is used near a power supply or other
heat-generating objects.
Use the H7BX within the specified ratings for vibration, shock,
and splashing water.
The H7BX is not oil resistant. Do not use it in locations subject
to oil.
Install the H7BX well away from any sources of excessive
static electricity, such as pipes transporting molding materials,
powder, or liquids.
Store the H7BX within the specified ratings. If the H7BX has
been stored at temperatures of 10 C or lower, let it stand for
3 hours or longer at room temperature before turning ON the
power supply.
Maintain voltage fluctuations in the power supply within the
specified range.
Internal elements may be destroyed if a voltage beyond the
rated voltage is applied.
When the power is turned ON, an inrush current will flow for a
short time (approx. 10 A for 2 ms). Depending on the power
Locations subject to sudden or extreme changes in
temperature.
Locations where high humidity may result in condensation.
Locations subject to direct sunlight.
Locations subject to corrosive gas.
Locations subject to excessive dust or dirt.
Precautions for Safe Use
Caution
● Installation and Wiring
● Handling
supply capacity, operation may not start. Be sure to use a
power supply with a sufficient capacity.
Use a commercial power supply as the AC power supply for
the H7BX. Using an inverter output with an output frequency of
50/60 Hz as the power supply may cause the H7BX to
produce smoke or become damaged by burning.
Use a switch, relay, or other device with contacts so that the
rated power supply voltage will be reached within 2 s. If the
power supply voltage is not reached quickly enough, the
outputs may malfunction.
Use a switch, relay, or other device with contacts so that the
rated power supply voltage will be reached within 2 s. If the
power supply voltage is not reached quickly enough, the
outputs may malfunction.
To mount the H7BX to a panel, attach the two supplied
adapters to the left and right sides of the H7BX, and securely
tighten the knurled screws on the adapters by hand,
maintaining a balance between them. Damage may result if
the knurled screws are excessively tightened with pliers or
other tools.
Be sure to wire the terminals correctly.
Up to two wires of the same size and type can be inserted into
a single terminal.
Do not connect more than two crimp terminals to each H7BX
terminal.
Use the specified wires for wiring.
Applicable wire: AWG 24 to AWG 18 (equal to a cross-
sectional area of 0.20 to 0.82 mm
Solid wire or twisted wire (copper), operating temperature over
70 C.
Separate the H7BX, the devices that generate input signals,
and input signal wires from any potential sources of noise,
such as high-voltage lines.
Do not use organic solvents (such as paint thinner or benzine),
strong alkaline, or strong acids because they will damage the
external finish.
Approximately 14 V will be output to the input terminals when
the H7BX is used with the key protection input terminals and
no-voltage input (NPN input) is used. To prevent charging
accidents, connect a diode to the power supply circuit of input
devices if input devices are used with a power supply of less
than 14 V.
Do not connect loads that exceed the rated output current.
The output elements may be destroyed, possibly resulting in
short-circuit or open-circuit faults.
When using heaters, be sure to use a thermal switch for the
load circuit.
Always connect a diode to protect against counter
electromotive force when using an inductive load. H7BX
electromotive force may destroy output elements, possibly
resulting in short-circuit or open-circuit faults.
Install a switch or circuit breaker that allows the operator to
immediately turn OFF the power, and label it to clearly indicate
its function.
Check that the display (backlight and LCD) is operating
normally. Some operating environments may accelerate
deterioration of the indicators, LCD, and resin components
and cause display malfunctions. Periodically inspect and
replace parts.
