3.7.4 Equipment operating temperature and humidity. Equipment shall
operate within the temperature range 4 for operating equipment and the humidity
specified in MIL-E-16400.
3.7.4.1 Compartment ambient conditions. The equipment shall operate when
subjected to the compartment ambient conditions specified in section 204 of
MIL-STD-1399. The equipment shall operate at any relative humidity up to 95
percent.
3.8 Wiring fixtures. Wiring fixtures shall consist of dummy back section
modules mounted in a frame, thus simulating the back section(s) of the actual
production switchboard. Terminal boards or box mounted connector receptacles,
without inserts (dummy connector receptacles in accordance with MS3105), for
each incoming ship cable shall be mounted on the dummy modules to permit the
installing activity to terminate and form up ship cables prior to receipt of
the actual switchboard back sections. Mating ship cable connector plugs for
each wiring fixture shall be supplied and shipped with the wiring fixture (see
5.1.3). The applicable back section connector location drawing will provide
the information regarding the ship connectors required (see 6.2.1). It is not
required to paint the wiring fixtures. Wiring fixtures shall be bolted not
welded in place.
3.9 Installation and checkout parts. Quantities of parts shall be pro-
vided for use during installation and check out (testing) periods (INCO kits)
so that use of onboard repair parts will not be required. Quantities of items
as listed in table V shall be provided for each switchboard on each ship. These
parts are intended for use only by the switchboard service engineers during
installation and checkout of the switchboards prior to completion of the ship
(see 5.2). Tools and any repair parts remaining after checkout and acceptance
of the switchboard will be turned over to the ship.
