WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or connected equipment, disable the generator
set as follows: (1) Move the generator set master switch to the
OFF position. (2) Disconnect the power to the battery
charger. (3) Remove the battery cables, negative (--) lead
first. Reconnect the negative (--) lead last when reconnecting
the battery. Follow these precautions to prevent starting of the
generator set by an automatic transfer switch, remote
start/stop switch, or engine start command from a remote
computer.
Prevent the generator set from starting by moving the
generator set master switch to the OFF position;
disconnecting power to the generator engine start
battery charger, if installed; and disconnecting all
generator engine start battery cables, negative (--) leads
first.
Connect the generator set remote starting circuit to the
engine start terminals located on the transfer switch
contactor assembly. See Figure 2-13 through
Figure 2-18 for the locations of the engine start
terminals, which are labeled on the unit with a red decal.
Refer to the generator set installation manual for wire
size specifications.
The engine start contact ratings are shown in
Figure 2-12.
2.6.3 Auxiliary Contacts
Connect the auxiliary contacts to customer-supplied
alarms, remote indicators, or other devices. Auxiliary
contacts provide contacts that close when the transfer
switch is in the Normal position and contacts that close
when the transfer switch is in the Emergency position.
Refer to the schematic diagram provided with the
transfer switch to identify which auxiliary contacts are
closed on Normal and which are closed on Emergency.
Figure 2-13 through Figure 2-18 show the locations of
the auxiliary contacts for different models. The auxiliary
contact ratings are shown in Figure 2-12.
