PM1000-DAP Wiring, Generic
Revision 5 Page 3 200-191-0000
Section 2 Installation
2.1 General Information
The PM1000-DAP comes with hardware
necessary for installation.
Installation of the PM1000-DAP, using the
available wiring and hardware supplied, re-
quires special avionics installation knowledge
other than described in FAA Advisory Circular
43.13-2. It is the installer's responsibility to
determine the approval basis for this installa-
tion. An FAA From 337, or other approval may
be required. See Appendix B for example of
FAA Form 337.
2.2 Unpacking and inspection
The PM1000-DAP was carefully inspected
mechanically and thoroughly tested electroni-
cally before shipment. It should be free of elec-
trical or cosmetic defect.
Upon receipt, verify that the parts kit P/N
250-003-0001, includes the following:
2.3 Equipment installation pro-
cedures
1. Using the template, drill six holes in the
instrument panel in a location convenient to
the pilot positions.
2. Insert the PM1000-DAP from behind the
instrument panel, aligning the holes for the
knobs, LED, and switch.
3. Place the faceplate over the knob shafts and
secure, using the two # 4-40 round head
screws provided.
4. Install the knobs over the volume and
squelch control shafts.
2.4 Cable harness wiring
To complete the installation, a wire harness
must be made as shown in wiring diagrams.
There are many variation of dual ACP in-
stallation. Although there are many successful
installations, PS Engineering cannot supply
technical advice in any case other than as de-
scribed in these appendices.
The PM1000-DAP is connected to the exist-
ing jacks. To connect intercom into the aircraft
audio system, parallel the appropriate set of ca-
bles from the intercom to the Aircraft Radio
Headset Jacks. See the wiring diagram for all
details of the wiring.
