Section II -Installation
2.1 GENERAL INFORMATION
2.1.1 SCOPE
This section provides detailed installation and interconnect instructions for the UPS Aviation Technologies
SL10-Series Audio Selector Panel/Intercom System and SL10M-Series Audio Selector Panel/Intercom
System with internal Marker Beacon.
With the exception of the internal marker beacon receiver, the SL10, SL10S, SL10C and SL10SC are
identical to the SL10M, SL10M-S, SL10M-C, SL10M-S-C. All units will be identified hereafter as the
SL10, where the information applies to all.
Please read this manual carefully before beginning any installation to prevent damage and post installation
problems. Installation of this equipment requires special tools and knowledge. The equipment must be
installed by an appropriately rated Certified Aircraft Repair Station, in accordance with applicable
regulations.
NOTE: The SL10-Series-S requires specialized knowledge and tools for an effective installation. An
appropriately rated Certified Aircraft Repair Station must install this equipment in accordance with
applicable regulations. UPS Aviation Technologies, warranty is not valid unless the equipment is installed
by an authorized UPS Aviation Technologies, dealer. Failure to follow any of the installation instructions,
or installation by a non-certified individual or agency will void the warranty, and may result in an
unairworthy installation.
2.2 Unpacking and Preliminary Inspection
Use care when unpacking the equipment. Inspect the units and parts supplied for visible signs of shipping
damage. Examine the unit for loose or broken buttons, bent knobs, etc. Verify the correct quantity of
components supplied with the list in Section 1.6 (B). If any claim is to be made, save the shipping material
and contact the freight carrier. Do NOT return units damaged in shipping to UPS Aviation Technologies. If
the unit or accessories shows any sign of external shipping damage, contact UPS Aviation Technologies to
arrange for a replacement. Under no circumstances attempt to install a damaged unit in an aircraft.
Equipment returned to UPS Aviation Technologies for any other reason should be shipped in the original
UPS Aviation Technologies packaging, or other UPS approved packaging.
2.3 Equipment Installation Procedures
2.3.1 Cooling Requirements
Forced air cooling of the SL10 is not required. However the unit should be kept away from heat producing
sources (i.e. defrost or heater ducts, dropping resistors, heat producing avionics) without adequate cooling
air provided.
NOTICE: To reduce the amount of heat dissipated in the audio selector panel, when used in a 28
Volt aircraft, it is required that the 15 W, 15 Watt dropping resistor (p/n 701-015-1501) be
installed in series with the power input.
If the SL10/M-S is installed in a 27.5 VDC aircraft system, a 15 W, 15 Watt dropping resistor (p/n 701-015-
1501) should be installed. Failure to do so will generate unnecessary heat inside the unit and may void UPS
Aviation Technologies's warranty.
2.3.2 Mounting Requirements
The SL10 must be rigidly mounted to the instrument panel of the aircraft structure and within view and
reach of the pilot position(s). Installation must comply with FAA Advisory Circular AC 43.13-2A. The unit
may be mounted in any area where adequate clearance for the unit and associated wiring bundle exist.
NOTE: The mounting hole configuration for the SL10 is identical to the KMA-24 Audio Selector
Panel. See Appendix B
