2.4 — Rear Panel Connections
Please re-read section 1.3 for safety instructions.
To connect the Rear Panel
All Connections, except those to the CT core of the ELNet LT
Energy & Powermeter
are made via terminal connector plugs
(Voltage input, Power Supply, Communication etc.).
Maximum recommended tightening torque for the connector
screws is 0.5 Nm.
The CT cores of the ELNet LT
Energy & Powermeter
are
located externally on the rear of the instrument and the lead
from the leg of the external Current Transformer must pass
through in the correct direction.
NOTE!
Ensure all the connections to the leads of the current
transformer wiring are secure and there is no mechanical
strain on the wire. The cross section of the leads to the
current transformer must be compatible to the power of the
current transformer. We recommend a power transformer
with at least 3VA and the length of the wiring of the
transformer no longer than 3m.
Insert the leads from side “L” of the external Current
Transformers to the ELNET current transformers side “L” and
from side “K” of the ELNET current transformers back to side
“K” of the external transformers.
