To connect the terminal to the weighing platform, the supply normally includes a pre-wired cable

installed on the weighing platform, i.e. analog or digital.

The cable screen must always be connected to the metal protection cap of the 9/15-pin
connector.
Do not route the connection cable to the weighing platform together with cables routed to power
drives.
