Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before
working on the generator set.
Remove the negative (--) lead first
when disconnecting the battery.
Reconnect the negative (--) lead last
when reconnecting the battery.
WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or equipment connected to the set, disable the
generator set as follows: (1) Press the generator set off/reset
button to shut down the generator set. (2) Disconnect the
power to the battery charger, if equipped. (3) Remove the
battery cables, negative (--) lead first. Reconnect the negative
(--) lead last when reconnecting the battery. Follow these
precautions to prevent the starting of the generator set by the
remote start/stop switch.
Hazardous voltage.
Can cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
are in place.
Moving parts.
WARNING
Grounding electrical equipment. Hazardous voltage can
cause severe injury or death. Electrocution is possible
whenever electricity is present. Ensure you comply with all
applicable codes and standards. Electrically ground the
generator set, transfer switch, and related equipment and
electrical circuits. Turn off the main circuit breakers of all
power sources before servicing the equipment. Never contact
electrical leads or appliances when standing in water or on wet
ground because these conditions increase the risk of
electrocution.
Short circuits. Hazardous voltage/current can cause
severe injury or death. Short circuits can cause bodily injury
and/or equipment damage . Do not contact electrical
connections with tools or jewelry while making adjustments or
repairs. Remove all jewelry before servicing the equipment.
Electrical backfeed to the utility. Hazardous backfeed
voltage can cause severe injury or death.
Connect the
generator set to the building/marina electrical system only
through an approved device and after the building/marina
main switch is turned off. Backfeed connections can cause
severe injury or death to utility personnel working on power
lines and/or personnel near the work area. Some states and
localities prohibit unauthorized connection to the utility
electrical system. Install a ship-to-shore transfer switch to
prevent interconnection of the generator set power and shore
power.
6.2.2 Circuit Breaker Installation
1. Place the generator set master switch in the OFF
position.
2. Disconnect the generator set engine starting
battery, negative (--) lead first.
3. Remove the six screws from the right side junction
box panel and remove the panel.
4. Install the circuit breaker on the new panel with the
screws and washers. Position the ON side of the
circuit breaker toward the rear of the junction box.
See Figure 6-3.
5. Attach stator leads L1, L2, and L3 to the extension
leads (if supplied) or to the line side of the circuit
breaker. See Figure 8-3.
Note: Insulate leads with electrical tape after
connecting extension leads to stator leads.
6. Connect the neutral connection stator leads to the
L0 stud.
Note: Verify that terminal positions and previously
made line lead connections allow room for
load connections to load studs.
7. Connect the load side of the circuit breaker to
customer-supplied craft wiring. Connect the
neutral lead to the L0 stud. See Figure 8-3.
8. Attach the new panel to the junction box using the
original six screws. See Figure 6-3.
