BHS MCP and for the connection between the BHS MCP to the BHS field
devices.
2) Beyond each provided feeder, the BHSC shall furnish and install services,
feeders, and fused disconnects for branch circuits from each MCP as
specified and furnish and install panel boxes, wireways, conduits,
conductors, transformers, fuses, equipment and materials required to
complete the fully functional electrical power distribution for the operation
of BHS. If additional power is required, the COTR shall be informed
immediately upon discovery.
3) The BHS field wiring work shall be part of BHS scope of work under
BHSC.
c. Motors and Efficiency: Motors shall be in accordance with the requirements of the
Energy Policy Act (EPAct) efficiency standards. For motor which is controlled by
Variable Frequency Drives (VFD), the motor shall be inverter duty type and its
motor insulation system shall be complied with NEMA MG-1 Part 31. Motors
shall be listed and labeled by Underwriters Laboratories (UL). Motors shall be by
one manufacturer throughout this Work.
d. Drive Horsepower: Size conveyor drives so that starts can be made under full load
conditions. BHSC shall identify horsepower requirements for each conveyor drive
using the requirements identified herein. Requirements for determining the
horsepower rating for each drive are listed herein and shall be complied with in the
calculations.
e. Variable Frequency Drives (VFD): Provide VFDs on all equipment where the
manufacturer requires or recommends their use or as defined on the BHS
Drawings. Where an equipment manufacturer requires or recommends use of a
VFD, the BHSC shall coordinate with equipment manufacturer for VFD
operational and location requirements or recommendations. VFD locations shall
be submitted for review and acceptance. Each VFD shall be mounted at the
conveyor/close to the conveyor that it is controlling, not in a centralized motor
control panel. The VFD shall be equipped with external appropriately sized
dynamic brake resistors and heat sink.
f. Radio Interference: BHS equipment provided or its installation shall not cause
interference with communications within the airport or between the airport and
aircraft or ground vehicles. BHS electrical and electronic equipment, including
inter-connecting wires and cables shall be designed to operate without malfunction
in the presence of normal electro-magnetic emissions generated by other
equipment installed or used at the airport. The normal airport environments shall
include various electrical motors and controls, power tools (including welders),
radar, automotive vehicles, communications equipment, etc. Provide isolation
transformers and line suppression, if required.
g. The BHSC shall submit a summary of power load requirements for each system to
the COTR to verify the feeder size. Refer to submittal requirements.
h. Uninterruptible and Conditioned Power (UPS): The BHSC shall provide
Uninterruptible Power Supply (UPS) and conditioned power regulation for control
and network equipment in the MCP. The BHSC shall be responsible to size the
UPS for the actual equipment provided in order to meet the functional
requirements of the BHS as stated herein.
