Precautions for Safe Use

Grounding
• The Smart camera casing and grounding wire of the input output cable must be grounded ac-

cording to Class D grounding (grounding resistance of 100Ω or less).

• Do not share the ground wire with other equipment or connect it to the beams of the building.

It could be adversely affected.

• Keep the ground line as short as possible by setting the grounding point as close as possible.
• The FHV body enclosure, the I/O connector enclosure, the EtherNet connector enclosure,

and the lighting connector enclosure are all at the same potential (FG) and are connected to
0V via a capacitor and a resistor in the internal circuit.

• When connecting to a PLC, or other external device, ensure that FG of the Smart Camera

and the FG of the external device are grounded so as to have the same electric potential.
Depending on the grounding method, a potential difference may occur between the Smart
Camera and the external device, which may result in equipment failure, or malfunction.

• When the positive (+) terminal of 24 VDC power supply is grounded.

‐

Inside of an external device, the shell of an Ethernet connector and SG should not be con-

nected. [

‐

Inside of an external device, 0V and FG should not be connected. [

Since FG and 0V will make short-circuit like below diagram, do not ground the positive (+)
terminal.

Precautions for Correct Use

Power Supply and Wiring
• When using a commercially available switching regulator, ground the frame ground terminal.
• If there is a surge on the power supply line, please use a surge absorber, depending on the

usage environment it is connected in.

• After wiring is complete, but before turning on the power supply, check whether there is incor-

rect connection such as power supply error, load short circuit, etc., and that there is the prop-
er load current. Malfunction, or damage may occur due to incorrect wiring etc.

• Wiring should be done in a state that there is no load on the cables and connectors.
• Do not turn off the power while saving data to the Smart Camera. Doing so causes the data

in the memory to be corrupted, resulting in the product not operating properly upon the next
start-up.

• Before turning power OFF, confirm that data save processing is completed according to the

following guidelines.

－

When the data save process is performed by operation on the smart camera: The data

save process is completed and the next operation is enabled

－

When the data save process is executed by a communication command: Processing of the

corresponding command has been completed and BUSY is OFF

• When touching a terminal part or a signal wire in a connector, take anti-static measures using

a wrist strap or another device to prevent damage from static electricity.

• Do not turn OFF the power while any message is displayed indicating that a task is in prog-
