Starting Procedures
When using this product for the first time, pursue work while making sure to avoid omission and incorrect
wiring by referring to the procedure below. "PC" stated in this section means "PC software".
This section explains the procedure for starting up the Gateway Unit. For the settings and wiring of each of
the individual devices, controllers, and actuators connected to the network, refer to the individual device's
Instruction Manual.
