MIL-PRF-49192A(CR)
3.4.1 Leakage current. Leakage current shall not exceed 3.5 milliamperes (mA) if an
open circuit should occur between an accessible part/component and ground. Accessible parts are
defined as control shafts with knobs removed, switches, recessed controls, calibration and
adjustment controls, and all other electro-mechanical parts/components which may pose a hazard
to the operator/maintainer.
3.4.2 Fuses and circuit breakers. Fuses and circuit breakers shall be provided to
disconnect the equipment from the power source in the event of excessive current drain. Either
common or separate fuseholders may be provided. If only one fuseholder is used (common), the
equipment shall be provided with the 115VAC fuse installed and the 230VAC fuse shall be
stowed with the accessories.
3.4.3 Input power switch. A front panel mounted power switch shall be provided. Visual
indication shall be provided on the front panel to show when the equipment is energized. Visual
indication may be accomplished by digital displays, lamps, or other means which clearly indicate
that the equipment is energized. The switch shall break both sides of the input power source.
3.4.4 Connectors. The input and output connectors shall be series "BNC" type female
connectors except for the RF Output, which shall be a series "N" type female connector.
3.5 Enclosure requirements. The equipment shall be housed in an enclosure that has no
openings on the top surface and provides protection from mechanical shock, and conditions
associated with bench top use in environmentally controlled areas. The enclosure shall be capable
of being rack mounted if specified in the contract or purchase order. The contractor shall supply
a conversion kit to convert the enclosure for rack mounting. The conversion kit shall include all
hardware required to configure the equipment for rack mounting. If the height or width of the
front panel is less than the height or width of the rack, the conversion kit shall provide filler panels
to accommodate the equipment. No part of the equipment shall protrude above or below the
front panel when the enclosure is rack mounted.
3.6 Marking and identification. Reference designations shall be used to identify each part,
subassembly, circuit board, and component. The marking/identification of these parts shall be
placed so that they will be clearly visible without having to remove, unsolder, or disassemble the
components/parts of the equipment. Warning markings shall warn of the location, nature, and
extent of a hazard. Warning marking shall have a high contrast between the warning letters and
the background colors, be located as close as possible to the hazard area, and be as permanent as
the life expectancy of the equipment.
3.6.1 Identification plate. The equipment identification plate shall contain the following
data:
a. Nomenclature
b. Manufacturer's name and code
