Before you apply power to the AFE, follow these steps.
1. Open the power structure enclosure door.
2. If present, remove the protective barriers.

.
3. Check for zero volts between DC+ and DC-.
4. To perform forward and reverse biased diode tests, use a digital

.
5. Confirm that wiring to the AFE (AC input, ground, DC bus, and I/O)
is connected to the correct AFE terminals, and is secure.
6. Verify that AC line power at the disconnect device is within the rated
value of the AFE.
7. Verify that the control power voltage is correct.
8. Whenever possible, isolate the AFE from the rest of the DC bus system
to enable the AFE to be powered separately.
