WIRING DIAGRAM MANUAL
CAUTION: MAKE SURE
THAT FLUID DOES NOT
CONTACT WIRES, AND
REMOVE ANY FLUID
FROM THE WIRES,
THE HARDWARE
THAT
HOLDS THEM, OR
AVIONICS AND ELECTRICAL
EQUIPMENT. COLLECT AND DISCARD ANY FLUID SPILLED
WITH CLOTHS, PLASTIC
SHEETS, AND CONTAINERS.
FLUID CONTAMINATION CAN CAUSE WIRE INSULATOR
DETERIORATION
AND
SHORT CIRCUITS.
(4) Wires shall not be routed closer
than 3 inches to components producing
heat in excess of
140°F. Wires required
to connect with heat producing components
shall be routed directly away
from
the component and maintain the 3 inch
clearance thereafter. Wiring operating
in elevated
temperatures
shall be wrapped
with tape or contained in conduits.
(5) Wires and cables shall be positioned or protected to avoid contact with rough or irregular surfaces
and sharp
edges.
(a) All wiring shall be protected from
chafing by the use of grommets, protective
sleeves, by
proper support and correct routing.
(b) All screws or metal edges that are within 0.20 inch of a wire or cable shall be coated with
Glyptal, protected by nylon caterpillar-type grommets or other protection.
(c)
Wiring shall be routed to
avoid contact with moving
parts.
(d) Wiring around sharp edges should be avoided at all times.
CAUTION: USE A CLOTH TO COVER ANY WIRES, AVIONICS OR
ELECTRICAL
EQUIPMENT
THAT IS IN A LOCATION
WHERE METAL CHIPS OR SHAVINGS CAN FALL. BE
SURE TO REMOVE ANY METAL CHIPS OR SHAVINGS
FROM WIRES, AVIONICS AND ELECTRICAL EQUIPMENT.
CONTAMINATION FROM METAL SHAVINGS CAN CAUSE
WIRE INSULATOR DETERIORATION AND SHORT
CIRCUITS
(e) Wiring shall be routed so they will not be crushed or pinched during installation.
Lightly coat wire with
petroleum jelly or water before pulling
through pressure feed-thru.
Leave enough slack in wiring to accomplish the following:
(a)
Permit
staking
of terminals.
(b) Ease of maintenance.
(c)
Permit free movement
of shock-mounted equipment.
(d) Prevent
mechanical strain on
wiring and wiring supports.
(e) Provide adequate drip and service loops.
CAUTION:
DRIP LOOPS MUST BE ARRANGED SO THAT DRIP FROM
LOOP DOES NOT FALL ON EQUIPMENT WHICH MIGHT
BE ADVERSELY AFFECTED. ON MOISTURE RESISTANT
CONNECTORS,
DRIP LOOPS
MAY BE OMITTED WHERE
SPACE IS LIMITED. COAXIAL CABLE ASSEMBLIES
IDENTIFIED AS IMPEDANCE
MATCHING UNITS
MUST BE
A SPECIFIED LENGTH. DO NOT SHORTEN CABLE TO
REMOVE EXCESS SLACK.
(8) The securing of wire groups, bundles, sleeves, adapter clamps and tape shall be accomplished
with a clove hitch knot secured with a square knot. Refer to Figure 203.
(a) MIL-T-713 twine and Sta-straps shall be limited in use to operational temperatures of less
than 200°F.
(b) The free ends of the MIL-T-713 twine shall be a minimum of 3/8 inch long.
(c) Wire groups
or bundles shall be tied at intervals
not to exceed 12 inches.
