10. INTERCONNECTING CONTROLLERS AND SITRAD INBOX
10.1 FOR A ROBUST ELECTRICAL INSTALLATION, OBSERVE THE FOLLOWING RECOMMENDATIONS:
- Use a 2-way cable, minimum 24 AWG;
- Preferably, use cables with mesh shielding to protect the communication line from outside interference;
- Avoid splicing the cable;
- Use terminal blocks to connect controllers. Besides facilitating the connection, they have a protection feature;
- Avoid connections longer than 2 meters between the connection block and the controller;
- Use a maximum of
32 devices
connected to each Interface.
