The PTO drive shaft should be maintained in as straight a line
as possible. Install the generator so the drive line is aligned to
within 5 degrees (10 degrees Max). The 2510/2512 PTO units
will require about 50 Hp to maintain full output, be sure that
the auxiliary drive on the vehicle transmission and the gear
reduction box is capable of the expected mechanical load. It
is generally recommended that the drive shaft be balanced to
minimize drive line vibration and stress.
Make sure no binding
exists in generator or gear box. If binding is found, locate the
cause and correct it before proceeding
E. PRE-WIRE SYSTEM CHECK:
WARNING: Personal Injury
When working on or around these generators, do not wear
loose fitting clothing or any articles that may get caught in
moving parts.
Before wiring the generator to the distribution load circuits,
the installation and operation of the drive system and
generator should be checked to insure proper drive line,
engine and generator operation.
Use the following check List to verify correct installation
before starting the engine:
1. Drive line straight and tight.
2. Unit mounting base and hardware solid and bolts
properly torqued.
3. Ventilation clear and protected.
4. Clearance on all sides and service access on both
ends
5. Generator output leads protected from grounding.
After completing the above checklist, the generator is ready
for the initial start-up test.
F. INITIAL START AND TEST PROCEDURE
CAUTION:
Make sure that all tumbling bar lock pins are engaged and
that all safety shields are in place before operating the
PTO generator.
1. See vehicle manufacturers instructions for operating
procedures. The generator should be turning at
specified rpm and producing correct voltage and
frequency. If the generator fails to operate as speci-
fied, stop the engine and refer to the trouble shooting
section of this manual.
2. With the engine running smoothly, and at the desired
speed, check the no-load voltage and frequency.
Generator leads G1 to G3, should read 240 Volts
nominal(240 TO 255 volts). Leads G1 to GN, and G3 to
GN both should read a nominal 120 volts(120 to 127
volts) at 60 Hz. It may be necessary to adjust the
voltage regulator to obtain the proper voltage. The
voltage regulator is located on the left hand side of the
generator end cover. Final voltage adjustments must
be done on the voltage regulator. The regulator may
not effect the no-load voltage to any degree.
*****Notice *****
If for any reason during the check-out procedure the
voltage and frequency are not correct, stop the engine and
refer to the troubleshooting procedures.
After verifying the voltage and frequency are correct, prepare
for final wiring of the generator by disabling the drive system
and or engine. The generator can now be connected to the
load circuits.
G. GENERATOR ELECTRICAL POWER CONNECTIONS
ALL wiring should be done by a licensed electrician, and
should conform to the national electrical code and with state
and local regulations.
The generator power output leads are marked G1(A & B) ,
G3(A & B) and GN(A & B). We use parallel leads from the
generator to reduce the wire size and make them eaiser to
handle. The A & B wires are always paired together.
A main line circuit breaker must be installed in the load
distrubution panel on the vehicle. The G1 and G3 wires are
routed to the mainline circuit breaker in the distribution panel.
The neutral lead GN is run to the neutral terminal in the
distribution panel.
Note! Most codes require that the neutral conductor be
“bonded”’ (grounded directly to the frame of the generator).
Check local codes to insure compliance. Refer to the national
electrical code NEC for portable/ mobile equipment. No
further electrical connections are required.
The load current carrying wires must be sized to handle
the maximum load current without excessive voltage drop.
By NEC code, conductors must be heavy enough to handle
the full current rating of the main line circuit-breaker (or
fuse) in the load distribution panel protecting the conduc-
tors.
All wires should be installed in rigid or flexible conduit.
Because of the many different types of wiring service,
feeder, and distribution panels used on rescue equipment,
no specific wiring instructions can be provided.
*************
*****WARNING******
************
If auxiliary (shore/commercial) power may also be con-
nected to the load for demonstration, training or alternate
source power, an isolation switch must be installed. An
isolation switch will prevent feed back of commercial power
into the generator or generator power into commercial line.
When the load is connected to the generator there must be
absolutely no feedback from the generator to the power line
or from the power line to the generator during any operating
condition. When correctly connected, the design of the wiring
control system prevents an possibility of feedback. Improper
installation can create a serious hazard that could result in
equipment damage, serious personal injury or death.
