INSTALLATION

3.3CONNECTING THE SEHI TO THE POWER SOURCE

Note: The SEHI has a universal power supply. This allows you to connect the SEHI to power sources from 90 Vac to 264 Vac, 47-63 Hz.

To connect the SEHI to the power source:

1.Plug the power cord into the back panel of the SEHI.

2.Plug the other end of the power cord into a grounded wall outlet.

3.Verify that the PWR LED is on, this indicates that the SEHI is receiving power. After the SEHI runs a self test, the CPU LED blinks green indicating normal operation. If the LED remains red, the processor is faulty.
