Mechanical Considerations
The Autoranging MegaPAC can be mounted on any of four surfaces using standard
8-32 or 4mm screws. The chassis comes with four mounting points on each surface;
maximum allowable torque is 20 lb-in. The maximum penetration is 0.15 in. (3,8mm).
When selecting a mounting location and orientation, the unit should be positioned so
air flow is not restricted. Maintain a 2 inch (5,1cm) minimum clearance at both ends of
the Autoranging 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 30 CFM of air.
Avoid excessive bending of output power cables after they are connected to the
Autoranging MegaPAC. For high-current 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 Autoranging MegaPAC is supplied with serrated, flanged
hex-nuts on all output studs. Therefore, thread locking compounds or lock washers are
not required. The maximum torque recommended on flanged nuts is 45 lb-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.
