The filter compartment (see Figure 38 - Frame 1,
Figure 39 - Frames 2, 3) is cooled by air that enters
through the ventilation grill (1), passes the IFU
inductors (2), circulates up through access holes
to the filter resistors(3), and exits to the fan (4).
Cabinet design
Heavy-duty 2.5 mm [12 gauge] external panels with
integral frame structure incorporate cabinet
strength and stability.
