Site Selection and Preparation
Installation Guidelines For 50 Hz Air-Cooled Generator Sets 17
Fire Prevention
The generator set must be installed at a safe distance
away from combustible materials. Engine, alternator, and
exhaust system components become very hot during
operation. Fire risk increases if unit is not correctly venti-
lated, is not correctly maintained, operates too close to
combustible materials, or if fuel leaks exist. Also, accu-
mulations of flammable debris within or outside the gen-
erator set enclosure may ignite. Distance Requirements
See Figure 3-2 . Minimum clearances must be main-
tained around generator set enclosure. These clearances
are primarily for fire prevention, but also to provide suffi-
cient room for removing front and end panels for mainte-
nance purposes.
