NOTES FOR FIGURES 5-2 & 5-3:
1. Selecting the grounding scheme is dependent upon the controller interface.
2. The current loop path must be completed for the system to operate.
3. The ungrounded loop is not truly isolated from ground. Isolators are required if this configuration is needed by the controller interface.
