GENERAL REQUIREMENTS
• The installer should be familiar with the installation requirements and techniques to
be used in securing the bay(s) to the floor.
• This product is intended only for installation in a Restricted Access Location on or
above a non-combustible surface.
• This product is intended for installation in Network Telecommunication Facilities (CO,
vault, hut, or other environmentally controlled electronic equipment enclosure).
• This product is intended to be connected to the common bonding network in a
Network Telecommunication Facility (CO, vault, hut, or other environmentally
controlled electronic equipment enclosure).
• Front and rear access is required for installation.
• Typical industry standards recommended minimum aisle space clearance is 2' 6" for
the front of the bay(s) and 2' for the rear of the bay(s). See also next paragraph.
• Rectifier ventilating openings must not be blocked and temperature of air entering
Rectifiers must not exceed rated Operating Ambient Temperature Range found in
System Application Guide SAG582140000. Distance from rear of a
Power/Distribution or Power Only Bay to a wall or other solid structure must not be
less than 6 inches. This assures proper airflow through the Rectifiers.
• The system consists of from 1 to 10 bays, depending upon your power requirements.
All bays that are designed to be bussed together must be placed in a line adjacent to
each other, with no space between bays. It is recommended to place the Primary
Power/Distribution or Power Only Bay on the far right or far left end of the bay line-
up, and to expand the system to the left or right of the Primary Power/Distribution or
Power Only Bay. This allows simple cable connections between bays, and a
consistent MCA Bay numbering scheme. The Primary Power/Distribution or Power
Only Bay is identified by the MCA as Bay #1. The other bays are numbered
consecutively, following the bay-to-bay cabling scheme. Thus, bays are numbered
#1-#10 from right to left or from left to right. The Primary Power/Distribution or Power
Only Bay may be placed in the middle of the bay line-up, expanding the system to the
left and right of the Primary Power/Distribution or Power Only Bay. In this
configuration, bay-to-bay cabling MUST start with the Primary Power/Distribution or
Power Only Bay, then each Secondary Power/Distribution or Power Only Bay and
Distribution Only Bays are daisy-chained into the cabling string. Remember, the
Primary Power/Distribution or Power Only Bay is identified by the MCA as Bay #1,
the other bays are numbered consecutively following the bay-to-bay cabling scheme.
