For the main power input, a 14 VDC installation requires two aircraft power and two aircraft ground
connections be used for each main power input used. A 28 VDC installation requires a minimum of one
each power and ground connection, but two are recommended.
CAUTION
A power connection on P4006-44 is only required if NAV SUPERFLAG and/or G/S SUPERFLAG is
utilized.
The power inputs P4001-19 and -20 provide power for all functions of the 400W Series unit except the
COM transmitter and the NAV and G/S SUPERFLAG outputs.
4.2.2 Lighting Bus
CAUTION
Connection of the lighting bus to incorrect pins can cause damage to the unit that will
require return to the factory for repair. Ensure that the lighting bus is connected to the
correct pins and does not short to any adjacent pins prior to applying power to the unit,
including the lighting bus.

The 400W Series unit can be configured to track 28 VDC, 14 VDC, 5 VDC or 5 Vac lighting buses using
these inputs. Alternatively, the 400W Series unit can automatically adjust for ambient lighting
conditions based on the photocell. Refer to Section 5.3.7 for configuring lighting inputs.
