Precautions for Safe Use
• If using an I/O cable 20 m long, confirm that the power supply output is 24 VDC or higher. If it is lower
than 24 VDC, the product does not operate.
• Cut off unnecessary signal wires so that they do not contact any other signal wires.
• After wiring the cables, confirm if the power supply is appropriate, if there is miswiring such as short-
circuit of load, if the load current is appropriate, and if FG is connected appropriately. Otherwise, the
product may be broken due to miswiring etc.
• Take enough safety measures such as a failsafe circuit before using the product.
• Be sure to apply Class D grounding (100Ω or lower grounding resistance) to the case of the smart
camera and the ground wire of the I/O cable.
• Do not share the ground wire with some other devices or connect it to the beam of the building. The
product may be adversely affected.
• Determine the contact point as near as possible to shorten the ground wire as much as possible.
The product may be adversely affected.
Ground
• Make sure the power supply circuit of the FH Sensor Controller is insulated from the internal circuit.
Refer to this manual or Instruction sheet.
• When the connected camera to Sensor Control comes packaged with a base, make sure to mount
with the base. Since the enclosure of the camera main body made of metals is short-circuited with
the internal circuit, the internal circuit might be short-circuited with FG if no base is used, so that fail-
ures or malfunctions may be caused.
Perform Class D grounding (with a grounding resistance of 100 Ω or less).
Keep the ground line as short as possible by setting the grounding point as close as possible.
Ground the FH Sensor Controller independently. If sharing the ground line with other devices or con-
necting it with a building beam, the Sensor Controller might be adversely effected.
• Check wiring again before turning on the FH Sensor Controller.
• Do not ground the plus (+) terminal when the FH series Sensor Controller is connected to the
FH-SC12/FH-SM12. Doing so may cause a short circuit of the internal circuit, resulting in a malfunc-
tion.
The internal circuit is possible to be given damage, it can be cause the failure.

• Do not ground the plus (+) terminal of the 24 VDC power source when the FH series Sensor Control-
ler is connected to the FH-MT12 with a USB cable. Doing so may cause a short circuit of the internal
circuit, resulting in a malfunction.
