O represents shielded wire, and all marked grounding points must be effectively grounded.
The transmitter housing is grounded by default, so field equipment must be effectively grounded.
Only the current output has reverse connection protection (no damage but not working),
current limiting and voltage limiting protection. Reverse connection of other output signals will cause damage to the transmitter.
