An internal 48 VDC power adapter is also available. The 36-72 VDC (nominal 48V) adapter uses a ferrite
clamp and a terminal block connector (see Figure 9 below). The black and red leads wrap around the ferrite
clamp three times. To connect the power, tighten the screws on the terminal block connector on the power
cord into the terminal block connector on the 2884.
