Installation environment
Avoid the following locations to install the HX.
- Excessive dusts, salty air, or conductive materials
(iron powder, etc.)
- Direct sunlight.
- Temperature less than 0 °C or more than 55 °C.
- Humidity less than 5 % or more than 95 %.
- Dew condensation.
- Direct vibration or impact to the unit.
- Corrosive, explosive or combustible gases.
- Water, chemicals or oil splashing on the HX.
- Close to noise emission devices.
Mounting
- Mount the HX on a metal plate and install in a cabinet as
follows.
Other
equipment
A：50 mm or more
B：10 mm or more
- Be sure to ground the cabinet, the metal plate, and
metal duct otherwise there is a risk of malfunction.
- Take appropriate measures when the HX system
installed in locations :
• Influenced easily due to noise or static electricity or
other forms of noise.
• Under strong electromagnetic field.
• Close to power supplies.
- Installation to a DIN rail
(1) Mounting to a DIN rail
1] Hook the claw of HX rear to the DIN rail.
2] Press the HX into the DIN rail until it clicks. Because
HX is fixed to the DIN rail without fixing brackets,
fixing brackets is not required.
Figure 1 Mounting to a DIN rail
(2) Removing from the DIN rail
1] While lowering the DIN rail fixing mounting lever
toward the bottom,
2] Raise the HX upward to remove.

Wiring for Power Supply
- Appropriate emergency circuitry, interlock circuitry and
similar safety measures should be added to the system.
- Appropriate safety measures should be included in the
system for unexpected breaking of wire or malsignal
caused from instantaneous power failure.
- Install external earth leakage breakers to avoid short
circuit accident.
- In case of the following operations, turn off power.
Otherwise, there is a danger of breakdown and/or injury
and/or fire.
• Mounting or dismounting HX.
• Assembling cabinet or machine including HX.
• Wiring.
- Install EMC filter specified in Table 1 or similar. Using
insulation transformer with shield is recommended. Use
the isolation AC-DC power supply that is conformed CE
marking for power supply to HX.
- When using HX in an equipment, supply power to DC
connector shown in Figure 3. DC jack is for debugging
on the desk purposes only.
- Wire the power supply according to Figure 4.
- Assemble the power supply cable according to Figure 5.
- Use the power cable of 1.25 to 2.0 mm
recommended length of the power line is 3 m or less.
- Be sure to ground with 100
grounding terminal (FE terminal) with a 2.0 to 2.5 mm
wire. The recommended length is 20 m or less.
