Mechanical Considerations
The 3-Phase MegaPAC and 4kW 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 20lb.in. The maximum penetration is 0.15in [3,8mm].
When selecting a mounting location and orientation, the unit should be positioned so air flow is not
restricted. Maintain a two inch minimum clearance at both ends of the 3-Phase MegaPAC and 4kW
MegaPAC and route all cables so air flow is not obstructed. The standard unit draws air in at the
fan side / AC input side and exhausts air out the load side. If air-flow ducting is used, use caution, as
sharp turns could present back pressure to the 3-Phase MegaPAC and 4kW MegaPAC. The fans move
approximately 50CFM of air for the 4kW MegaPAC and 30CFM for the 3-Phase MegaPAC. The 4kW
MegaPAC has a second fan for additional cooling capabilities.
Avoid excessive bending of output power cables after they are connected to the 4kW MegaPAC or
3-Phase MegaPAC. For high-current outputs, use cable ties to support heavy cables in order to minimize
mechanical stress on output studs. Be careful not to short-out to neighboring output studs. The
3-Phase MegaPAC and 4kW MegaPAC is supplied with serrated, flanged hex-nuts on all output studs,
so thread-locking compounds 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.
