Master station power supply modules are field replaceable units that
can be removed from an operating system
so long as the input power
source to the module being replaced has been disconnected
. Refer to Section 8.4 Replacing
Modules for information on removal and installation.
DC power supply modules are available for several different input
ranges. These modules have interchangeable connectors. Make sure
the supply is within the rating for the module installed.
When installing DC Power Supply modules, torque thumbscrews to 10
in-lbs, or approximately ¼ turn past hand tight, to insure optimum heat
transfer through thermal contact connector on the rear of the unit.
When connecting DC Power Supply modules, the length of the power
cable
MUST
be no longer than 3 meters.
