Mechanical Considerations
The DC MegaPAC
™
can be mounted on any of four surfaces using standard 8-32/M4 screws. The
chassis comes with four mounting points on each surface; maximum allowable torque is 20lb.in. The
maximum penetration is 0.15in [3,8mm].
When selecting a mounting location and orientation, the unit should be positioned so airflow is not
restricted. Maintain a 2in [5,1cm] minimum clearance at both ends of the DC MegaPAC and route all
cables so airflow is not obstructed. The standard unit draws air in at the fan side and exhausts air out
the load side. If airflow ducting is used, avoid sharp turns that could create back pressure. The fan
moves approximately 30CFM of air.
Avoid excessive bending of output power cables after they are connected to the DC MegaPAC. For
high-current inputs and outputs, use cable ties to support heavy cables minimizing mechanical stress
on output studs. Be careful not to short-out to neighboring output studs. The DC MegaPAC is supplied
with serrated, flanged hex-nuts on all output studs, so LOCTITE
®
or lock washers are not required.
The maximum torque recommended on flanged nuts is 45lb.in. Never loosen the inner nut on a
ConverterPAC
™
. This nut supports the hardware inside the ConverterPAC and is factory torqued.
Avoid applications in which the unit is exposed to excessive shock or vibration levels. In such
applications, a shock absorption mounting design is required.
