2.1
Installation Overview
The installation of the VP-X is accomplished in five main steps, and the
amount of work for each step is shown by the relative size of the boxes
shown above.
Following these steps will increase the likelihood of a trouble-free electrical
system. Each step is described in detail later in this manual. You can optionally
swap steps 2 and 3 and set everything up on the bench first.
We recommend that you read through all five steps so that you better
understand the system prior to beginning the planning step.
Taking the time up front to carefully plan your electrical system will pay big
dividends later on.
2.2
System Overview
The VP-X provides circuit protection, circuit switching, trim and flap control,
and a host of other functions. The electrical devices are controlled by
conventional switches that are wired into the VP-X. The VP-X integrates with
popular EFIS units, which display electrical system information. Trim and flap
position information from the VP-X is also displayed on the EFIS, and circuit
faults can be reset from the EFIS.

2.3 Supported Bus Architecture
The VP-X supports a single main aircraft electrical bus architecture, with
one or two alternators and one or two batteries. An additional independent
backup or ‘e-bus’ can be added as well for redundancy (described later in
this manual).
The Vertical Power PPS is
a solid-state replacement
for contactors. More
