Onan RDJF Series User Manual

RECONNECTIBLE GENERATORS, BEGIN
SPEC AA
The factory ships all special order sets with in-
struments on the control panels completely wired for
the voltage code or voltage specified on the
customers purchase order. Standard sets without
instruments are shipped with the T'-T
4
or T
1
-T'
2
output leads separated in the output box. These
single phase and broad range generators are connec-
tible or later reconnectible to provide any of the
output voltages shown in Figure 8 •
Code 3C or 53C Reconnectible Generators: The
single phase, 60 and 50 Hertz generators have output
leads T', T
2
, T
3
, and T
4
available for making the single
phase voltage and load connections shown in Figure
8 at the installation site. Grounding procedure should
comply with local codes.
Code 18R or 518R Reconnectible Generators: The
three phase, broad range, 60 and 50 Hertz 12 lead
generators have output leads T
1
through T
12
available
for making several single and three phase voltage
load connections shown in Figure 8. Grounding
procedure should comply with local codes.
When connecting the output leads, be sure to connect jumper WIO
on the voltage regulator printed circuit board between terminal V
4
(common) and V, V
2
, or V
3
as listed on the reconnection diagram.
A broad range generator is capable of generating numerous
different oufput.voltages as indicated by the reconnection diagram.
Code 9X Generators: These special order three
phase, 60 Hertz, 4 wire, generators are prewired at the
factory to provide 347/600 VAC. Output leads T
1
, T
2
,
T
3
, and T
0
are available for connection to the load
wires. See connection diagram. Grounding
procedure should comply with local electrical codes.
GENERATORS PRIOR TO SPEC AA
Revolving field generators, used with the RDJF series
prior to Spec AA, have four leads. Connections for
these generators are shown in Figure 9.
Reconnectible Single Phase Generators: Code 3C
models, such as RDJF-3C are reconnectible for use
as 120/240 volt 3 wire; 120 volt two wire; or 240 volt 2
wire units (Figure 8) exceptwhen optionally equipped
with a meter panel.
Delta Generators: On these generators, T
0
is the
center tap between T
1
and T
2
; T
0
is normally not
grounded but may be grounded if required.
Grounding: A number 8 or larger wire should be used
to connect the generator housing to a rod or pipe that
penetrates into moist earth. If a solderless connector
is not provided on thegenerator, connectthe ground
wire at the battery ground stud on the engine.

FIGURE 10. BATTERY CONNECTION
BATTERY CONNECTIONS
The battery is. connected for negative (-) ground,
Figure 10. Be sure all battery connections are secure.
Battery polarity must agree with th^eetifieMocated
in the control box. If battery ground'm.dst be changed,
reverse the rectifier connection in the control box/
f ^erseii "/
CAUTION { If battery polarity is wiwg, damage wiM occur
within 3 minutestobUe,.stoppecfor 5 seconds
while running. Alternator windings will be damaged almost instant-
ly if battery charging circuit is shorted between resistor R21 and the
B1 end of the charging winding.
See Specifications for minimum 12 volt battery re-
quirements. Connect battery positive (+) to starter
engaging solenoid terminal post, Figure 9. Connect
battery negative (-) to a good ground on the engine.
Sets may be equipped for 24 volt cranking and battery
charging circuit. Battery connections are similarto 12
volt connections. Provide two 12 volt batteries con-
nected in series (one battery negative to the other
battery positive).
OPTIONAL ALARM
The GND terminal on the remote control terminal
block is for a customer supplied alarm at a remote
location to warn of emergency shutdown. Refer to
Wiring Diagram for proper voltages.
