Extend the CT Cable
1. If required, the CT cable may be extended up to a theoretical maximum of 100m.
x To avoid interference and reduce the loss of signal, extension cables should be
as short as possible. Extensions of 20m or less are recommended.
x Extension cables must be a screened ‘Twisted Pair’. A screened twisted pair
within a CAT6 computer network cable may be used.
NOTE: Twisted pairs within a CAT cable are indicated by their matching colours.
Do NOT use conductors of different colours, interference may be induced.
Connect the CT Cable to the Chargepoint
IMPORTANT: A suitable cable gland must be installed to the chargepoint enclosure to
accept the CT cable and maintain the IP rating of the enclosure.
1. Locate the EV Charge Controller
enclosure and the connector
marked CT.
2. Connect one CT clamp wire to the
H+ terminal on the circuit board
connector.
3. Connect the other CT clamp wire to
the H- terminal on the circuit board
