Electrical Connections
Accidental or remote starting can
WARNING
cause severe personal injury or death. To pre-
vent accidental starting, disconnect the nega-
tive (−) battery cable from the battery before
working on the genset.
HAZARDOUS VOLTAGE! Touching
WARNING
uninsulated live parts inside the genset and
connected equipment can result in severe per-
sonal injury or death. For your protection, stand
on a dry wooden platform or rubber insulating
mat, make sure your clothing and shoes are dry,
remove jewelry from your hands and use tools
with insulated handles.
Improper wiring can cause fire or
WARNING
electric shock resulting in severe personal inju-
ry or death.
GENERATOR
Wiring Methods
All wiring methods, connections, wire ampacities,
equipment grounding and materials must be in-
spected and comply with applicable regulations.
Use flexible conduit and stranded conductors for
connections to take up the movement and vibration
of the genset. See Page 23 for the location of the
AC power output box and its conduit knockouts.
Note: All feed-through holes in decks and bulkheads
for wiring must be sealed to prevent exhaust gases
and flammable vapors from entering the rest of the
boat. Wiring conduit must be sealed inside as well as
outside
Generator Connections / Reconnections
Make generator connections and reconnections as
required (Page 22).
Note 1: When reconnecting the generator for a differ-
ent output voltage, make sure the line circuit break-
ers are suitable for the new output. Replace them if
necessary with ones of appropriate rating.
Note 2: See Page 19 if it is necessary to change fre-
quency or to readjust voltage.
Grounding
The genset, power supply wiring and all connected
electrical equipment must be bonded to the com-
mon grounding system of the boat in accordance
with applicable regulations.
Faulty
WARNING
equipment can lead to fire or electric shock re-
sulting in severe personal injury or death.
Transfer Switch
When the boat has provisions for connection to
shore power, the genset must be connected to the
boat electrical system through an approved transfer
switch to prevent backfeed.
Backfeed to shore power can lead
WARNING
to electric shock resulting in severe personal in-
jury or death. Prevent backfeed by connecting
the genset to the boat electrical system through
an approved transfer switch.
Load Balancing
Loads should be balanced as closely as possible
across the generator phases.
REMOTE CONTROL
Remote Control Connector
The sealed 8-pin DeutschR connector for remote
connections is stowed inside the genset. Remove
the access cover on the left end of the enclosure.
Remove and discard the solid rubber slot plug (not
the one with the round plastic insert). See Page 23.
Pull the connector out, fit the wire grommet into the
slot and secure the access cover. Remove the pro-
tective cap over the connector pins and join the con-
nector and its mate from the e-Series Digital Display
and/or remote switch and meters.
Onan e-Series Digital Display
Up to three (3) Onan e-Series Digital Displays may
be connected for remote control and monitoring of
the genset. The e-Series Digital Display is not igni-
tion protected and must therefore be installed in
spaces isolated from gasoline fuel sources. Follow
the installation instructions in the Display kit.
