Installation Guidelines

• Mounting: Slide the module onto the S7-300 mounting rail and connect it to the backplane bus using the provided bus connector.
• Wiring: Use shielded cable for the load cell connection to minimize noise interference. Ensure the shield is properly grounded at the module or via the designated earthing terminal.
• Configuration: Use the RS232 interface to connect a PC with SIWAREX U software to calibrate the scale and set operational parameters.
• Remote Display: Use the TTY interface specifically for connecting remote weight displays to ensure distance communication without electromagnetic interference.
