IMPORTANT:
•
Ensure the source of the reference phase is isolated before performing these steps.
•
The SS9007 Mini CT Meter is not rated as a protection device and may only be connected
to a circuit that is protected up-stream by an approved circuit breaker.
3.
Mount the device in the switchboard.
4.
Wire the Current Transformer (CT) to the device, taking care to match the CT leads with the
appropriate "CT Black" and "CT White" terminals.
5.
Clip the CT on to the target load conductor, ensuring that the arrow on the CT points
towards the load or generator (
away from the grid
).
Connect the output of a MCB, RCD, or other protection device to the “Live” terminal of the Mini CT
Meter, and a neutral line to the “Neutral” terminal. The protection device used for this purpose
need not necessarily be on the same circuit that the device will be monitoring (i.e. the circuit to
which the CT is connected), although care should be taken to ensure the current source and voltage
share the same phase.
