There must be a service disconnect in the commercial power line ahead of the transfer switch.
Typical installations of a transfer switch are shown in Figure 17 on page 25 and Figure 19 on page 27.
Cabinet dimensions and weights are listed in Table 2 on page 27.
Choose a vibration-free mounting surface that supports the weight of the switch. Avoid locations that are
near flammable liquids or gases, or are hot, moist, or dusty.
WARNING
An electrical arc occurs during transfer that can ignite a flammable atmosphere, resulting in
severe personal injury or death. The switch must not be located near batteries, fuel tanks,
solvents, or other sources of flammable liquids or gases, or in areas sharing ventilation with
such sources.
