Main Circuit Breaker Protection
Before beginning installation of your Sensor3 dimmer rack(s), make sure you have installed a main
circuit breaker cabinet or other readily accessible input power disconnect device. See
Sensor3 CE Rack Specifications, page 36
WARNING:
Energising the System
Sensor3 racks should only be energised by an authorised ETC representative. Wiring errors in
unauthorised installations may endanger personnel or cause system damage and failure.
WARNING:
CAUTION:
Use 90°C Copper Wire
Use only 90°C-rated copper wiring installed in accordance with all applicable electrical codes.
.
CAUTION:
Prepare for Installation
Check the shipping container for physical damage.
If you find damage, document it to help with a claim against your shipper.
Unpack your order and check the contents against the packing list to be sure your order
is complete.
If you discover a problem, contact your dealer or nearest ETC office.
Dimmer racks installed without an accessible power disconnect
device cannot be serviced or operated safely.
Do not attempt to energise the system without proper approval.
Energising the system without correct inspection may result in
serious injuries.
Energising your system without proper inspection may result in equipment
damage that may not be covered under your warranty!
A two-wire circuit with separate phase and neutral conductors is
required for every branch circuit that will be connected to the dimmer rack.
Shared neutral circuit arrangements are not recommended for phase-control
dimming systems due to harmonics and potentially elevated neutral currents
in a shared neutral arrangement.
For retrofit installations where shared neutral circuits are already installed, or
track lighting installations where the track has a shared neutral, consult ETC
Technical Services for rack installation guidelines.
The Neutral of the supply to the dimming system should have at least the
same cross-sectional area as the phase conductors
for individual rack power requirements.
