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. |
