Precautions for Safe Use
Power Supply and Wiring
• Make sure to use the product with the power supply voltage specified by this manual.
• Provide the power from a DC power supply (safety extra-low voltage circuits) that has been
taken measures not to generate high-voltage.
• Make sure to tighten all screws in mounting.

FH-2000/FH-5000 Series
Precautions for Safe Use
Power Supply and Wiring
• Keep the power supply wires as short as possible (Max. 2 m).
• Use the wire of a suitable size (AWG 10 to 16) according to the current consumption.
Ground
• The power supply circuit of the FH Sensor Controller is insulated from the internal circuit.
• When a base is packed in a camera that will be connected to the Sensor Controller, make
sure to mount the camera using the base. Since the enclosure of the camera body is con-
nected to the internal circuits, mounting the camera without using the base allows the internal
circuits to be directly connected to the ground, which may cause malfunction or failure.
• Apply Class D grounding (grounding resistance: 100 [Ω] or less)
• Provide the grounding point as close to the product as possible to shorten the grounding wire.
• Wire the grounding wire for the Sensor Controller independently. If the grounding wire is
shared with other devices or connected to a building beam, the Sensor Controller may be ad-
versely affected.
• Check the wiring again before turning on the power.
Connect the FH-2000/FH-5000 Series to FH-MT12
Do not ground the positive terminal of the 24 VDC power supply when connecting the Sensor
Controller and FH-MT12 using a USB cable. The internal circuits may cause a short-circuit and
result in malfunction.
Connect the FH-2000/FH-5000 Series to FH-SC12/FH-SM12 (12 megapixels camera)
Do not ground the positive terminal of the 24 VDC power supply when connecting the Sensor
Controller and a 12 megapixels camera like FH-SC12 or FH-SM12.
Other
• There are products in which the enclosure, mounting screw holes, or ground terminal are
short-circuited to 0 V inside (e.g., commercially available monitor products).
Connecting the enclosure, mounting screw holes, or ground terminal of such products to the
Sensor Controller with the ground terminal connected to the ground allows the 0 V reference
inside the product to be directly connected to the ground, which may cause equipment failure
or malfunction.
