Connecting the projector to AC power with a
permanent connection
Learn how to connect the projector to AC power with a permanent connection.
Warning! If not avoided, the following could result in death or serious injury.
•
A certified electrician must be present during installation to ensure the installation meets the
local electrical code.
•
SHOCK HAZARD! A dedicated, protected ground or earth wire must be installed on the product
by Christie qualified technicians or electricians before it can be connected to power.
•
Do not return the current through the ground or earth.
•
Always connect the ground or earth first to reduce shock hazard.
•
Use an appropriately sized strain relief connector with the knockout plate provided, to ensure
adequate environmental sealing and to prevent the AC supply cable from accidentally being torn
out or rubbing against the knockout plate.
When connecting the projector to AC power, follow all electrical codes for your location. In addition,
follow these recommendations:
•
Use a 30-32A, double-pole, UL-listed wall circuit breaker. It must be part of the building
installation and easily accessible.
•
Use 10AWG or 8AWG wiring.
•
When using 10AWG cables, the distance between the wall circuit breaker and the projector
must not exceed 20 m (65.6 feet).
•
When using 8AWG cables, the distance between the wall circuit breaker and the projector
must not exceed 30 m (98.4 feet).
•
For North American installations, use at least 10AWG copper wires to connect the main AC
supply to the projector’s ground lug.
Follow these steps to connect the projector to AC power with a permanent connection:
1. On the bottom of the projector in the front-right corner, loosen the two screws and slide the
plate forward to expose the terminal block.
