(7) Air cleaner
Make sure air cleaner element is installed. Recommended replacement element is United Air
Cleaner No. 250A13.
(8) Battery
Check fluid level in 12 volt battery. Fluid should cover plates.
C. Output Cable Installation
Units are normally supplied without a generator-to-aircraft cable.
(1) Cable requirements
Cable length is determined by the customer's requirements. It is recommended that the cable be
no longer than 30 feet (9 m). The cable should be two conductor with lug-type terminals on one
end and an AN-2551 plug connector on the other.
The recommended single conductor sizes for 28.5 volt DC, continuous rated amperage and 90C
(194F) rise is as follows:
for 285 amperes use 2/0 size
for 385 amperes use 4/0 size
for 530 amperes use 350 MCM size
NOTE: Some operators may wish to add a second cable assembly with MS-25019 plug connector for
starting aircraft such as Jetstar and Sabre liner.
(2) Cable connector
(a) Connect 28 volt conductors to output terminals on output terminal panel (Figure 1). Terminals
are identified POSITIVE and NEGATIVE. Tighten terminal nuts securely.
(b) Store cables in cable tray provided on top of fender, or on hangers on side of canopy if fend-
ers are not used.

2. Preparation for Storage

When a generator set is to be stored or removed from operation, special precautions should be taken to
protect the internal and external parts from rust and corrosion.
A. General
(1) The unit should be prepared for storage as soon as possible after being removed from service.
(2) Storage should be in a building which is dry and which may be heated during winter months.
(3) Moisture absorbing chemicals are available for use where excessive dampness is a problem, how-
ever the unit must be completely packaged and sealed if moisture absorbing chemicals are to be ef-
fective.
