◆1.9.1 GENERATOR
Install the generator set, in its protective enclosure, outdoors, where adequate cooling and ventilating air is always available. Consider these factors:
•Install the unit where air inlet and outlet openings will not become obstructed by leaves, grass, snow, etc. If prevailing winds will cause blowing or drift- ing, you may need to consider using a windbreak to protect the unit.
•Install the generator on high ground where water levels will not rise and endanger it.
•Allow sufficient room on all sides of the generator for maintenance and servicing. A good rule is to allow 3 feet of space on all sides.
•Where strong prevailing winds blow from one direction, face the generator air inlet openings to the prevailing winds.
•Install the generator as close as possible to the fuel supply, to reduce the length of piping.
•Install the generator as close as possible to the transfer switch. HOWEVER, REMEMBER THAT LAWS OR CODES MAY REGULATE THE DIS- TANCE.
DANGER
If the Auto/Off/Manual switch is not set to its OFF position, the generator can crank and start as soon as the battery cables are connected. If the utility power supply is not turned off, sparking can occur at the battery posts and cause an explosion.
Battery cables were factory connected at the genera- tor (Figure 1.5). Connect cables to battery posts as follows:
3.Connect the red battery cable (from starter con- tactor) to the battery post indicated by a positive, POS or (+).
4.Connect the black battery cable (from frame ground) to the battery post indicated by a nega- tive, NEG or
NOTE:
Damage will result if battery connections are made in reverse.

◆1.9.2 TRANSFER SWITCH
The transfer switch shipped with this generator is rated 100 amps maximum at 120/240 volts AC single phase. The enclosure of the transfer switch is NEMA
1.This type of enclosure is intended for indoor use only. Follow these rules:
•Install the transfer switch indoors on a firm, stur- dy supporting structure.
•To prevent switch distortion, level the switch if necessary. This can be done by placing washers between the switch enclosure and mounting sur- face.
•Never install the switch where water or any corro- sive substance might drip onto the enclosure.
•Protect the switch at all times against excessive moisture, dust, dirt, lint, construction grit and cor- rosive vapors.
