Power Supply Unit
An individual power supply unit is required with the 7400D data module
only when
it is used as a stand-alone module
. When the 7400D is rack-mounted in a 77A
rack-mount, the rack-mount provides powering capabilities for up to eight units.
The power supply unit connects a grounded AC outlet and the “POWER”
connector at the rear of the data module. This power supply unit provides the
necessary operating voltages for the data module.
