Recommended fan shroud design – rear cooling
Guidelines for rear cooling
■
Design the cooling shroud so that it encloses the full length of both the laser and the cool-
ing fan.
■
Fit the shroud snugly against the laser’s heatsink fins so air is ducted between the fins and
not around them.
■
For proper heat removal, open the shroud at the front to direct air flow through the laser.
■
Use a cooling fan rated for at least 8.5 m
3
/min (300 CFM) at a static air pressure of 23.9
mm H
2
O (0.94 in H
2
O) and position it approximately 150 mm (6.0") from the rear of the
laser.
Electrical connections
The following procedures describe how to complete electrical connections to v30 lasers. OEM v30 DC
power cables are manufactured from #12 AWG wire and measure 1 meter (40 inches) in length.
DC power supply
Note: The negative (–) side of the DC input to the laser is internally connected so that the laser chas-
sis serves as DC power ground. You should isolate the laser’s DC power supply so that the only
grounded connection is at the laser. Alternatively, you can mount the laser chassis on an insulat-
ing pad or film in order to electrically isolate the laser when other equipment is grounded to the
laser’s DC power supply.
