Fan tray
The fan tray (part FAN001-024) provides sufficient cooling for the 6 A and 9 A
MicroFlex e150. The fan tray might be required for the 3 A model when operating in
high ambient temperatures (see
Temperature derating
on page
132
). The fan tray
requires 23 - 27.5 V DC at 325 mA, which can be sourced from the same filtered
control circuit supply used for the MicroFlex e150. The MicroFlex e150 is UL Listed
(file NMMS.E128059) when used in conjunction with the fan tray, mounted exactly as
shown in the following diagram.

It is important that the fan tray is mounted in
close proximity to the MicroFlex e150 as
shown above. Failure to do so will result in
decreased cooling efficiency.
