For HART functionality, use power supplies or SPS input cards with HART mark. If this is not
possible, the interconnection must have a resistance ≥ 250 Ω (< 1100 Ω).
The signal line can be connected with or without ground. When connecting the ground (minus
side), make sure that only one side of the contact is connected to the equipotential bonding
system.
