SV-D700 / SV-D1000 Installation and Configuration
SkyView System Installation Guide - Revision K 4-7
Electrical Installation
Use this section in conjunction with the information contained in Appendix C: Wiring and
Electrical Connections (notably Figure 89 on page 17-7). The wires and wire colors in this section
refer to the wires on the included SkyView Display Harness (SV-HARNESS-D37).
Power Input
SkyView displays have a primary power input that is compatible with 12 volt and 24 volt
systems (10 to 30 volts DC). There are two unterminated solid red primary power input wires
(to reduce current loading in each wire—these are not for redundancy and both should be
connected to the same power source) and two unterminated solid black primary ground wires.
Ensure that there is an appropriately rated circuit breaker or replaceable fuse on
the primary power input. A 5 amp circuit breaker or replaceable fuse is sufficient
for the majority of installations. Reference the Power Consumption Section of the
System Planning Chapter for more information.
Grounding
Ensure that all external devices that interface with SkyView have a common ground with
SkyView. If a device does not share ground with SkyView, it may not communicate properly.
Airplane Master Contactor / Relay Considerations
If your aircraft is equipped with a master contactor or a relay that is operated by the master
switch, it is imperative that the coil of the contactor or relay is protected by a diode to reduce
the voltage spike seen when the contactor is turned off. Without this diode, the aircraft system
can see spikes above 100V, which can damage Dynon equipment and other avionics.
While some contactors have this diode internally, many do not. Please verify the existence of
this diode before operating your Dynon equipment.
Backup Battery Connection and Operation Rules
SkyView displays have the option of an external backup battery (SV-BAT-320). The display
harness has a connector that mates with the connector on the backup battery. Simply
connecting the display to the battery using this connector enables backup battery functionality.
In the event of an electrical failure that causes SkyView to run on the SV-BAT-320, the SV-BAT-
320 supplies power to the SkyView display it is connected to, along with any connected SV-
ADAHRS-26X, SV-EMS-220, SV-ARINC-429, and SV-GPS-250 modules. Because of higher power
requirements, the SV-BAT-320 does not power Autopilot servos, the SV-XPNDR-26X, or any
other external device.
SkyView displays are only compatible with Dynon’s SV-BAT-320 battery pack. Do
not connect a lead-acid battery or any other battery as the charging algorithm is
optimized for the SV-BAT-320. Connecting any other battery may have detrimental
