2.16 Parallel Shelf Installation
CAUTION
Risk of personal injury or damage to equipment and
property. Always observe the following:
•
Do not use the internal BMM battery LVD contactor for
parallel applications where load current can exceed the 150
amps maximum rating of the LVD contactor.
•
Do not parallel BMM modules. A battery connection may be
made to a single BMM module, with maximum battery
current not to exceed the rating of the individual BMM unit
(150 amps).
•
Do not connect shelves in series, they are meant for parallel
operation only.

NOTE: Please review the ICT MPS Ultra Series of power supplies for pre-
configured 2RU power supplies with up to 12000 watts of DC power.
Use a secondary power shelf for applications that require up to an additional
6000 watts of DC power. The secondary shelf has no internal ICM, as it is
controlled and monitored by the ICM on the main unit, requiring only an
additional AC line input connection, a control jumper cable (ICT-JMP)
connection, and the installation of tie bars (ICT-PAR) to parallel the shelf
outputs.
The primary and the secondary power shelf must be installed as a set into
adjacent rack locations to ensure the output power tie bars and control cable
jumper will correctly fit.
