Current Transformers
When wiring current transformers into the system you must follow these considerations:
1. The maximum amperage allowed on the secondary is 5A. A 5:X ratio CT should be used where X is the maximum
primary amperage rating (e.g. 200A).
2. The CT power rating should be a minimum of 1VA.
3. The current transformer of each phase must be facing the same direction. See below.
4. The CT Common connection must be connected to the black wire on each current transformer.
5. The wires from the current transformers to the controller should be as short as possible.
6. The CT wires should be run in a separate conduit from the AC voltage wires.
NOTE : If readings are unstable with the configuration shown below, attempt connecting the CT Common's black wire
to the negative terminal of the battery. Ensure the connecting wire is as short as possible.
