Precautions for Safe Use
• Use only the cables designed specifically for the product. Use of other products may result in
malfunction or damage of the product.
• Always turn OFF the power of the FH-L series Sensor Controller and peripheral devices be-
fore connecting or disconnecting a camera or cable. Connecting the cable with power sup-
plied may result in damage of the camera or peripheral devices.
• Since cables to which bending is frequently applied is easily broken, use the robotic cable
type (bending resistant cable) to prevent damages.
• Do not apply torsion stress to cables. If not, it may cause damage to cables.
• Secure the minimum bending radius of cables. If not, it may cause damage to cables.
Precautions for Correct Use
• Check the following items on the communications cables that are used in the network.
- Are there any breaks?
- Are there any shorts?
- Are there any connector problems?
• When you connect the cable to the communications connectors on devices, firmly insert the
communications cable connector until it locks in place.
• Do not lay the communications cables together with high-voltage lines.
• Do not lay the communications cable near devices that generate noise.
• Do not lay the communications cables in locations subject to high temperatures or high hu-
midity.
• Do not lay the communications cables in locations subject to excessive dirt and dust or to oil
mist or other contaminants.
Cable
• For communication cable, use a shielded twisted-pair cable.
• The maximum cable length is 15 [m].
How to Connect
• Align the connector to the socket and press it straight into place, then tighten it with the screws on
both sides of the connector.
