c.
Receptacles should be located so as to minimize the amount of required cable bending.
When using series II connectors with large cables which must be bent at right angles, the
cables must have the right angle bend permanently established.
d. Series II connector should not be used with heavy jacketed cable and excessive overhang
moments, because of possible shell damage.
e. Series II connectors should not be used in areas of rough handling such as experienced near
engine removal, generators, support equipment, or portable equipment, etc.
f.
When mating series II connectors in areas of difficult visibility, care must be exercised to
make sure that all bayonet pins are engaged by the coupling ring, since it is possible to
engage only one bayonet pin and therefore only partially couple.
g. When mating series II connectors in areas of difficult visibility, care must be exercised to
make sure that connector plugs with pins are not coupled to receptacles with pins. This
situation will result in the contacts touching.
