3.4 CONNECTING TO A POWER SOURCE

NOTE: The MicroMMAC-T has a universal power supply that allows it to use power sources from 85 Vac to 264 Vac, 47-63 Hz.

To connect the MicroMMAC-T to the power source, plug the power cord into a grounded wall outlet. After the MicroMMAC-T runs a self test, the CPU LED blinks green to indicate normal operation. If the LED remains red, the processor is faulty.

3.5 RESETTING THE MICROMMAC-T

The MicroMMAC-T reset button is located on the left front panel as shown in Figure 3-6.
