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." |
