Sufficient ventilation is required around the laser rack to regulate the temperature of the laser
modules. See the following chart for airflow and heat load requirements. If necessary, air intake
and exhaust HVAC ducts can be installed. See
Add 15% more CFM to the airflow values in the chart for every 1000M above sea level.
Failure to comply may result in equipment damage.

Laser rack power requirements
A certified electrician must complete these and any other electrical installations.
•
Two single phase (100 - 240) VAC, 15 A, (50 - 60) Hz or other suitably rated branch circuits for
the laser system network switch and the laser bank manager.
•
One to four single phase (200 - 240) VAC, 30 A, (50 - 60) Hz circuits for the power distribution
unit, as specified in the following table. To protect from overcurrents, short circuits, and earth
faults, a 30 A circuit breaker for each circuit, which must be part of the building installation. The
disconnect device must be readily accessible in the same room as the laser rack.
•
Use wires suitable for at least 90 degrees Celsius for AC supply connections.
•
Use appropriately rated IEC 60309 plugs and receptacles as part of the AC power cord
connections.
•
Connect the AC feed to the AC terminals on the back of the power distribution unit.
