Generator MLCB (generator disconnect) can be locked in
OFF (OPEN) position for security during maintenance.
Use an appropriately-sized padlock (not included) with a
shackle long enough to pass through both lock tabs (B).
NOTE: DO NOT leave generator MLCB (generator dis-
connect) locked in the open (OFF) position during normal
generator operation. Leaving the generator MLCB (gen-
erator disconnect) in OFF (OPEN) position will prevent
generator from powering structure when placed in AUTO

Auxiliary Shutdown Switch

Equipment Damage. The auxiliary shutdown switch
is not to be used to power down the unit under
normal operating circumstances. Doing so will
result in equipment damage.
All generators are equipped with an external means of
shutting down the generator which complies with the lat-
est NEC code requirement. The primary generator shut-
down sequence is described in
Testing.
See Figure 2-11. An auxiliary shutdown switch is pro-
vided on the exterior of the generator back panel. This
switch shuts down the generator and disables restarts.
