controlled and monitored by the ICM on the primary 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.
Do not attempt to connect shelves in series, they are meant for
parallel operation only!
The master 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.

CAUTION
Risk of damage to equipment!
•
Do not use the internal BMM battery LVD contactor for parallel applications
where load current can exceed the 150A 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 (150A)
Install the Shelf Paralleling Bus Bars (ICT-PAR) and plastic bus bar covers as
shown in Figure 8, using the hardware included with the Hybrid Power Series.
Install the Parallel Control Cable (ICT-JMP) connecting the two RJ-11 style SHARE
ports as shown in Figure 8 to allow the Primary ICM to control the secondary
shelf. (Shelf slots 1 to 4 (front, L to R) are on the main shelf, slots 5 to 8 (front, L
to R) on the secondary shelf)
Connect alarm monitoring wiring to the Form-C contacts on the secondary shelf
if desired, to remotely monitor for secondary shelf module alarm conditions.
Connect a load to the parallel shelf outputs to utilize the combined power of all
power modules installed in the two shelves, or connect the loads to the back
panel output ports of any installed LDM modules for built in intelligent power
distribution.
