General Safety
DANGER! YOU MUST FOLLOW APPROVED SAFETY PROCEDURES.
Performing the following procedures may expose you to hazards. These procedures should be
performed by qualified technicians familiar with the hazards associated with this type of equipment.
These hazards may include shock, energy, and/or burns. To avoid these hazards:
a) The tasks should be performed in the order indicated.
b) Remove watches, rings, and other metal objects.
c) Prior to contacting any uninsulated surface or termination, use a voltmeter to verify that no voltage
or the expected voltage is present. Check for voltage with both AC and DC voltmeters prior to
making contact.
d) Wear eye protection.
e) Use certified and well maintained insulated tools. Use double insulated tools appropriately rated for
the work to be performed.
Voltages
AC Input Voltages
DANGER! This system operates from AC input voltage capable of producing fatal electrical shock. AC
input power must be completely disconnected from the branch circuits wiring used to provide power to
the system before any AC electrical connections are made. Follow local lockout/tagout procedures to
ensure upstream branch circuit breakers remain de-energized during installation. DO NOT apply AC
input power to the system until all electrical connections have been completed and checked.
DC Output and Battery Voltages
DANGER! This system produces DC power and may have a battery source connected to it. Although
the DC voltage is not hazardously high, the rectifiers and/or battery can deliver large amounts of current.
Exercise extreme caution not to inadvertently contact or have any tool inadvertently contact an output
terminal or battery terminal or exposed wire connected to an output terminal or battery terminal.
NEVER allow a metal object, such as a tool, to contact more than one termination or battery terminal at a
time, or to simultaneously contact a termination or battery terminal and a grounded object. Even a
momentary short circuit can cause sparking, explosion, and injury.

PLACING THE BAYS AND INSTALLING
INTERNAL/EXTERNAL BUSBARS
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.

NOTE! If you are installing List 2 and List 12 bays (with List 30, 31, or 32 PDSC), skip this procedure and
refer to “Placing and Securing List 2 and List 12 Power/Distribution Bays (with PDSC)".
•PDSC = AC Input 'Power Distribution Service Cabinet'.
•Refer to Figure 1 through Figure 18 as this procedure is performed. Figure 1provides a floor hole
drilling pattern.
•Bays are typically placed next to each other and bolted together. Refer to the previous Section,
GENERAL REQUIREMENTS, for bay line-up recommendations.
Procedure
Preparing the Bays
1. Remove all front Rectifier mounting position blank cover panels from each Power/Distribution Bay to
provide access to bay's floor mounting holes and leveling feet. Cover panels will be re-installed in empty
Rectifier mounting positions after all Rectifiers are installed. To do so: Remove the screws and ground
washers securing the cover panel. Remove the cover panel.
2. Remove the three rear cover panels from each Power/Distribution Bay. These cover panels will be re-
installed after all mounting and electrical connection procedures have been completed. To do so: Top
Panel: Loosen the screws securing the cover panel. Lift the cover panel until the screw heads clear the
keyhole slots. Remove the cover panel. Lower Panels: Remove the screws and ground washers
securing the panel. Remove the panel.
3. Remove the side cover panels from each Power/Distribution Bay (two per side) as follows, if equipped.
Note that you may leave the side cover panels on the "outside side" of the two end bays.
a) Remove the rear-most side cover panel as follows: Remove the screws and ground washers
securing the side cover panel. Screws are accessible from the rear of the bay through holes in the
side channels. After removing screws, pivot rear edge of cover panel outward, then slide cover
panel toward rear of bay to disengage tabs at the front of the cover panel from slots in the bay.
