Installation

cable_extension The wires of the current transformers can be extended if necessary, but note that this will increase the measurement noise slightly. In general: The longer the cables, the higher the noise floor. However, if the length is doubled, the additional error is still low (almost 0A).
mounting Chassis Mount (snap-on around the conductor)
DigiKey - KEMET C/CT-0810 product listing — "Mounting Type: Chassis Mount"
orientation There is an arrow printed on the CT labelled L <- K. Ensure the arrow points towards loads.
phase_matching Make sure the current transformers are connected to the correct phase wire and input terminal. The transformers are marked with an indicator showing which input port they belong to.
restriction It is not allowed to use the current clamps on bare wires.
