WARNING: EQUIPMENT DAMAGE
NEVER APPLY A LOAD TO THE GENERATOR UNTIL
YOU HAVE FIRST CHECKED THE VOLTAGE AT THE
TERMINAL BLOCKS OR THE CAM-LOCKS.
7. With the engine running smoothly check the no load
voltage and frequency on the digital display. The
voltage should be 208/240/480 AC depending on
which model you have and a frequency of 59.5
to 60.5 hertz (Hz).
If you have the proper voltage at the generator the next
step is to check the voltage at the customer connec-
tion points, wither the terminal block or the Cam-Lock,
that you intend to use. The voltage between the L, L2
and the L3 terminals should be the same as it was on
the generator front panel. The voltage should also be
checked between the hot terminals (L, L2 and L3) and
the N to be certain of a balanced voltage output and a
solid neutral connection. See the voltage table on page 9
for proper voltage reading in each selector switch posi-
tion. WHEN USING THE 20/240 VOLT THREE PHASE
(DELTA) SYSTEMS BE SURE YOU KNOW WHERE
THE HIGH VOLTAGE "WILD" LEG IS. IT MUST BE IN
THE SAME LOCATION ON THE GENERATOR SIDE AS
IT IS ON THE LOAD SIDE.
** Notice **
If for any reason during the check out procedure the volt-
age and frequency are not correct, depress the STOP/
RESET button and correct the problem before proceed-
ing.
8. Stopping - There are two ways to stop the unit when
t is in the manual mode. Pressing the STOP/RESET
button will stop the unit immediately. Pressing the
AUTO mode button will stop the unit but only after
the cool down timers have timed out and there Is no
remote start signal being sent to the unit.
E. REMOTE STARTING AND CONNECTION
(Standby applications)
. Complete the manual starting procedure above to
ensure the system is set up properly.
2. Ensure the engine control is in the “off” position dur-
ing installation of the remote start connections.
3. Locate the remote start terminal block. This terminal
block is located next to the full power connections,
behind the access door on the control panel.
4. Locate the remote start terminals in your remote
automatic transfer switch (ATS). The ATS terminal
block and wire numbers will vary with each ATS
manufacturer. The RP25 requires a contact closure
for start.
WARNING: EQUIPMENT DAMAGE
THE REMOTE “SIGNAL” MUST BE A “DRY” (NON-
POWERED) CONTACT CLOSURE. USING A POWER
CONTACT WILL CAUSE PERMANENT DAMAGE TO
THE ENGINE CONTROL MODULE.
5. For most installations 6-gauge wire is sufficient
to handle the control signal. On extremely long runs
increase wire size to minimize voltage drop.
6. Locate the neutral and full power output load connec-
tion terminal on the generator.
7. Locate and identify the “neutral” and “generator” con-
nections in the automatic transfer switch.
8. Connect the load block to the transfer switch using
the proper wire sizes. Refer to the National Electric
Code Handbook (NFPA 70) for proper wire type and
sizing. Use Table 30-6 for wiring run through con-
duit and table 30-7 for free air wiring.
Use extreme caution when installing the delta voltage
pattern. One power leg of this 3 phase pattern pro-
duces 208 volts measured from line to neutral. Be sure
to match the location of the generator wild leg to the
location of the wild leg on the incoming power service.
Failure to do so will cause equipment damage to any 20
volt load incorrectly connected to this line.
9. Connect the neutral to the transfer switch using the
same wire size.
0. For isolated neutral operation remove the jumper
wire between the ground lug and neutral connec-
tion block. Then route a ground lead back to system
ground.
. Ground the Mobile Diesel Generator set using an 8 ft.
copper ground rod or other approved grounding sys-
tem. Connect #4 Awg Copper cable from the ground
lug on the generator to the ground rod.
2. Depress the "RUN" button on the RP25 control panel
to start the generator set.
3. Check the voltage at the transfer switch. Verify that it
matches the incoming power line voltage line-to-line
and line-to-neutral on each leg.
4. Check the three phase rotation pattern. Ensure that
you have the same rotation, with both the generator
and the normal power source.
5. Depress the “STOP” button on the front of the
engine control. Let the unit stop and then depress
the “AUTO” button. The unit is now in AUTOMATIC
mode. Also be sure the "AUTO" light is lighted on
the control, this light tells you it is in automatic mode.
See control panel layout for additional information.
