3.2 Installation
NOTE: Any end-product/system incorporating or coupled
to a Lumencor Light Engine shall be fully evaluated to
verify all applicable safety and regulatory compliance
requirements prior to use.
When setting the RETRA (L) Light Engine up for use, place
the unit on a hard surface and avoid blocking or restricting
airflow at the air inlet (front panel; Figure 3) or exhaust
ports (rear panel) on the enclosure. Restricting the airflow
will cause the unit to operate at elevated temperatures and
will result in decreased product life and/or premature
failure.
The RETRA (L) Light Engine must be operated in a non-
condensing environment (dew point <10ºC with controlled
ambient temperature <30º C). Thermal overload protection
is provided by the on-board computer in conjunction with
an on-board temperature sensor. If the internal
temperature registered by the sensor exceeds 50°C
OR
the
fan rotor is stopped, all light output channels automatically
turn OFF and are locked in this state until the internal
temperature is below 50°C and/or the fan restarts. The
current reading of the on-board temperature sensor is
displayed on the front panel status display (Figure 3) and in
the GUI (Figure 5).
Connect the DC power supply to a grounded AC wall outlet
using the power cord supplied with the light engine.
Connect the DC output to the 6-pin receptacle on the front
