USB Connector

This section shows the wiring for a USB connector.
USB cable
Use a USB cable supplied with a connected device.
A cable with type A connector can be connected to this product.
Wiring procedure
■Connection
Check the insertion direction, and insert a USB cable into a connector.
After connecting the cable, take a measure to prevent it from falling out.
Page 78 Measure to Prevent a Cable from Falling Out
■Disconnection
Pull out the USB cable from the connector.
When a measure to prevent the cable from falling out is taken, remove the cable tie from a mounting base in advance.
Considerations
• Attach the provided dust-proof cover to protect an unused USB connector from dirt and dust.
• Connected devices must be installed in a control panel.
• For devices connected to this product, using the same power source is recommended.
• When a device to be connected has a 3-pin power plug or when the device or its power plug has a grounding wire, connect
the plug to a grounding receptacle or ground the grounding wire with a ground resistance of 100 ohms or less.
• Do not turn the power of the system/this product OFF, reset the hardware, restart Windows in this product forcibly, or
unmount/eject the USB Mass Storage Class-compliant device while accessing the files in a USB Mass Storage Class-
compliant device. Doing so may result in data corruption in the USB Mass Storage Class-compliant device or file system
error.
• If overcurrent occurs in a USB port used, some of the USB ports stop according to the port where overcurrent occurs.
(Page 72 Operation when overcurrent occurs)
• Do not connect a USB device with large current consumption and one of which data may be corrupted if disconnected
during operation (such as USB Mass Storage Class-compliant device) to ports in the same group if possible. If the current
consumption of USB devices is close to the maximum supply current, it is recommended to connect the devices via a self-
powered USB hub.
• When connecting multiple USB devices of which data may be corrupted if disconnected during operation, do not connect
them to ports in the same group if possible. Otherwise, when overcurrent occurs in the other group, such USB devices may
be required to be disconnected during operation for the recovery operation.
