Connect Line Power Wiring
ETC recommends routing line (feeder) cables first, load neutral
and load earth wires next, and load phase wires last.
CAUTION:
CAUTION:
Preparing Line Feed Cable
Line cable and power wire should enter the rack through the
designated top and bottom access points.
Line feed wires connect on the rack's line phase, neutral and
earth bus bars. Each bus bar has one or two 12 mm studs to
secure a lug connection for the line feed wires. The installer
must provide the line feed connecting lugs.
Pull the line phase, neutral and earth cables to the rack
through the openings you prepared previously.
Cabling Access" on page 15.
Step 1:
Pull the line phase, Neutral and Earth cables to
the rack through the openings you prepared
previously.
Step 2:
Cut the wires to length such that they reach the
correct stud
Step 3:
Prepare the end of the wire and fit the desired
termination.
Step 4:
Attach the lug to the correct phase, neutral or
earth stud as shown in
Connections on page
Step 5:
Tighten the lugs to 59.5Nm.

Line and load wires used with Sensor3
dimming systems must be copper. Do not
use wire containing aluminium or other
metals.
Dress wires neatly and avoid leaving
extra wire inside the rack. Too much
clutter (especially along the right side of
the rack) can restrict air circulation and
reduce cooling efficiency. If cabling
interferes with airflow during operation,
the rack may shut down due to
overheating.
