Power Supply Unit
A separate power supply unit is required with the 7400B Data Module.
This unit connects between 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.
Caution:
Make certain that the AC outlet to which you connect the
power supply is unswitched (for example, not controlled
by a wall switch or light dimmer).
Instructions for installing the power supply unit with an illustration are
provided in the hardware installation section of Chapter 2,
"Installation."
