3.2.2 Mounting and coolingthe MicroFlex e100
Ensure you have read and understood the Mechanical installation and location requirements in
section3.2. Mount the Micr oFlex e100 vertically on its rear side, the side opposite the front panel.
M5bolts or scr ews should be used to mount the MicroFlex e100. Detailed dimensions areshown
insection 3.2.1.
For effective cooling, the MicroFlex e100 must be mount ed upright on a smooth vertical metal
surface. The MicroFlex e100 is designed to operate in an ambient temperature of 0°C to 45°C
(32°F to 113°F). Output current must be derated between 45°C (113°F) and the absolute
maximumambient temper ature of 55°C (131°F). Within the ambient temperature range:
The3A model is des igned to operate without any additional cooling methods.
The6A and 9A models requirea forced air flow, passing vertic ally from the bottom to the top of
theMicroFlex e100case, to allow full rated curr ent at 45°C (113°F).
Temperaturederating characterist ics are shown in sections 3.2.3 to 3.2.5.
Note: Failureto meet c ooling air flow requirements will result in reduced pr oduct lifetime
and/or drive overtemperature trips. It is recommended to chec k periodically the
operationof the cooling equipment. Optional fan tray FAN001-024, mounted exactly
ass hown in section A.1.1., ensures that correct coolingis provided and allowsthe
MicroFlex e100 to be UL listed.
3.2.2.1 Effects of mounting surface and proximity
The proximity of the MicroFlex e100 to other
components could affect cooling efficiency. If
theMicroFlex e100 is mount ed besideanot her
MicroFlex e100 (or other obstruction), there
should be a minimum space of 15mm to
maintaineffective c ooling.
If the MicroFlex e100 is mounted above or
below another MicroFlex e100 (or other
obstruction),there s hould be a minimum space
of 90mm to maintain effective cooling.
Remember that when a MicroFlex e100 is
mounted above another MicroFlex e100 or
heat source, it will be receiving air that has
beenalready heated by the devic e(s) below it.
MultipleMicr oFlex e100 units mounted above
each other should be aligned, not offset, to
promoteair flow acrossthe heatsink s.
The derating characteristics assume the
MicroFlex e100 is mounted on 3mm thick (or
less) metal plate. If the MicroFlex e100 is
mounted on 10mm plate then the current
characteristics shown in sec tions 3.2.3 to 3.2.5
may be increased by up to 7% if there is no
forced air cooling, or 15% if forced air cooling
ispres ent.
It is recommended to allow approximately
60mmat the front to ac commodate wiring and
connectors.
