Precautions for Connecting Serial Interface

The serial interface is not isolated. The SG (signal ground) and FG (frame ground) terminals are connected inside this product. When the serial interface connector is D-Sub, connect the FG wire to the shell.

DANGER
ELECTRIC SHOCK AND FIRE
  • Verify that a ground loop is not created when you set up the system.
  • When the SG and FG on the external device are not isolated, connect the product's SG to the SG on the external device.
  • Connect the SG to a known reliable ground connection to reduce the risk of damaging the circuit.
Failure to follow these instructions will result in death or serious injury.
CAUTION
LOSS OF COMMUNICATION
  • Do not put excessive stress on the communication ports of all connections.
  • Securely attach communication cables to the panel wall or cabinet.
