NOTE: Read this entire manual before installing and operating the system. Upon receipt of a Vertiv™
Liebert® MBX Busway System, the installer should perform the following steps to ensure a top-quality
installation.
•Inspect the shipment for damage or signs of mishandling before unpacking the unit(s).
•Unpack the system components carefully. Use care to avoid puncturing the container with sharp
objects that could damage the contents.
•Remove the packing and vapor barriers and inspect the equipment for any obvious shipping
damage.
1.1 Mechanical Lifting
•Some sections of the busway system may require mechanical lifting due to their weight. Options for
mechanical lifting includes forklift, scissor lift, platform lift and block and tackle. A full assessment of
the risks should be carried out by the installer before commencing work.
•The Liebert MBX must be safely secured to the lifting apparatus before lifting.
•Always check that the weight of the load does not exceed the safe working load of the lifting
apparatus. Ensure that the lifting equipment is used according to the manufacturer’s guidelines.
1.2 Storage
•The Liebert MBX is delivered to the customer neatly stacked on a wooden pallet for ease of removal.
The maximum weight of the pallet will not exceed 5,500 lb. (2,500 kg).
•The Liebert MBX is protected from minor water ingress by an outer polythene wrap that should be
left in place until the track is mounted.
•If the Liebert MBX will not be installed immediately upon delivery, it should be stored in a clean, dry
area with temperatures maintained in the range of 32°F to 104°F (0°C to 104°C). The busway system
should never be stored outdoors.
•Storage/transport: Up to 40,000 ft. (12,200m) above mean sea level.

2.1 Power Feed Box
The Power Feed Box is a NEMA enclosure that provides connections for incoming power cables to the
Liebert® MBX Busway System. The Power Feed Box is usually the first component to be mounted on a run.
NOTE: The Power Feed Box should be installed at the correct height in accordance with the approved
drawings. Refer to the submittal drawing MBX-05-Sxxx and and MBX-17-Sxxx for installation height,
torque values and additional technical information. Contact your Vertiv™ representative for copies of
the appropriate submittal drawing.
Consult the design engineer's approved drawings for busway track installation requirements.
The power feed box may be installed using all-thread from the ceiling or Unistrut. For horizontal
installations, move the mounting brackets to the narrow side of the box. For vertical installations, move the
mounting brackets to the wide top side of the box. keep refer submittal drawing MBX-05-S00x and Figure
