3. Mounting

3.1 Mounting Environment
Mount the HD-500 in a location where no corrosive gases are present, where airflow is not stagnant, andwhere average humidity can be detected.
(If you have any questions regarding mounting environment, please contact us.)
• In an environment of corrosive gases, degradation of the humidity sensor will be quickened, and it willcause measurement errors. Avoid mounting in a location where the following gases are present:
Chlorine gas, Hydrogen chloride gas, Sulfur dioxide gas, Carbon dioxide gas, Nitric acid gas,Ammonia gas, Ethanol gas, Methanol gas, Cigarette smoke, etc.
• No water, oil, chemicals or their vapors come into direct contact with the instrument.
• A minimum of dust
• No exposure to direct sunlight, an ambient temperature of 0 to 50 (32 to 122 ) that does not change
rapidly• No mechanical vibrations or shocks• Mount the unit in a location where its operating humidity range is within 20 to 90 %RH.
Use the water-proof filter (THF-500, sold separately) in an environment where dew condensation occurs
because the sensor degradation will be quickened.
• The wire connecting the HD-500 to the “instrument to receive humidity” should be kept away from large
capacity electromagnetic switches or cables through which large current is flowing.
3.2 Mounting Method(1) Mount the HD-500 within a range of 90 degrees (between horizontal and upright). Otherwise water willenter through the gap between the sensor cap and the protective tube, and this will cause sensor
malfunction. (Fig.3.2-1)
Mount the protective tube perpendicularly placed to airflow, and keep the HD-500 50 mm or more of
distance from the wall. However, be careful about mounting direction of the humidity sensor HD-S2. See(Fig. 3.2-2) on p.4.
(2) Securely mount the HD-500 using the provided screws after opening the terminal box cover.
(3) After connecting the wire to the terminal, securely fix the moisture protection connector of theconnecting wire outlet and rubber packing for terminal box cover. Otherwise, terminal parts will becorroded and a measurement error will result.
Use the water-proof filter (THF-500, sold separately) in an environment where dew condensation
occurs.

4. Wiring
Warning

Turn the power supply to the HD-500 OFF before wiring or checking. Working on or touching
the terminal with the power switched ON may result in severe injury or death due to electricalshock.

Caution• When wiring the terminals of the HD-500, use a solderless terminal with an insulation sleeve in whichan M3 screw fits. Turn the power supply to the HD-500 OFF before wiring.
• Tighten the terminal screw (M3) using the specified torque. If it is tightened with excessive torque, theterminal screw (M3) may be damaged.
• The connecting wire (0 to 1 V DC) from the HD-500 should be kept away from other power lines andload lines.

Caution• Do not use any humidity sensors except HD-S2.
• Keep the socket and sensor terminals clean.
If they are not clean, correct measurement is impossible due to imperfect contact.
• Do not apply excessive force to the sensor, and do not touch the sensor with wet hands or withchemicals on them.
• Do not clean the sensor.
Replacement of the humidity sensor(1) Unscrew the sensor cap of the HD-500 counterclockwise, and pull it out straightly.

Sensor cap(Fig. 4.3-1)(2) Pull, straightly, the degraded humidity sensor (HD-S2) out of the socket.

Sensor terminal

Humidity sensor (HD-S2)(Fig. 4.3-2)(3) Set the new sensor (HD-S2) in the socket straightly.
The humidity sensor (HD-S2) has polarity. Therefore, fit the contra-insertion protection pin andon the humidity sensor.
