12 Sensor3 CE Rack (ESR3) Installation Manual
Connect Line Power Wiring
ETC recommends routing line (feeder) cables first,
load neutral and load earth wires next, and load
phase wires last.
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 12mm 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.
See “Rack Cabling Access” on page 11.
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
Figure 9: Line and Load Connections on
page 12 .
Step 5: Tighten the lugs to 59.5Nm.
C A U T I O N : Line and load wires used with Sensor3
dimming systems must be copper. Do not
use wire containing aluminium or other
metals.
C A U T I O N : 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.
