1S kW Generator
Z_ Proceed with caution! Generator power voltage
Js now supplied to the transfer switch, Contact
with live transfer switch parts will result in dan-
gerous and possibly fatal electrkal shock,
11. Connect an accurate AC voltmeter and a fre-
quency meter across transfer switch terminal
lugs E 1 and E2. Voltage should be 242-252 volts;
Kequency should read about 61-63 Hertz.
12. Connect the AC voltmeter test leads across ter-
minal lug E1 and neutral; then across E2 and
neutral. In both cases, voltage reading should be
121-126 volts AC.
13. Set the generator's main circuit breaker to its
OFF (or open) position. Let the engine run at no-
load tot a few minutes to stabilize internal engine
generator temperatures.
14. Set the generator's AUTO/OFF/MANUAL swifeh to
OFE The engine should shut down.
NOTE:
it is important not to proceed until certain that
generator AC voltage and frequency are correct
and within the stated limits. Oenerally_ if both AC
frequency and voltage are high or lo_; the engine
governor requires adjustment. If frequency is cor-
rect, but voltage is high or low, the generator's
voltage regulator requires adjustment.
2.4 GENERATOR TESTS UNDER LOAD
To test the generator set with electrical loads applied,
proceed as follows:
1. Set generator's main circuit breaker to its OFF
(or open) position.
2. Set the generator's AUTO/OFF/MANUAL
switch to OFE
3. Turn OFF the utility power supply to the transfer
swifeh, using the means provided {such as a util-
ity main line circuit breaker).

Z_ Do not attempt manual transfer switch opera-
tion until aH power voltage supplies to the
transfer switch have been positiveJy turned off.
Failure to turn off aH power vottage supplies
will result in extremely hazardous and possibly
fatal electrical shock,
4. Manually set the transfer swifeh to the STANDBY
position, i.e., load terminals connected to the
generator's E 1/E2 terminals. The transfer switch
operating lever should be down.
5. Set the generator's AUTO/OFF/iVlANUAL switch
to MANUAL. The engine should crank and start
irmnediatel_t
lo
G. Let the engine stabilize and warm tip for a few
minutes.
7. Set the generator's main circuit breaker to its ON
(or closed) position. Loads are now powered by
the standby generator.
8. Turn ON electrical loads. Apply an electrical load
equal to the fllll rated wattage/amperage capacity
of the installed generator.
9. Connect an accurate AC voltmeter and a frequen-
cy meter across terminal lugs E 1 and E2. Voltage
should be greater than 230 volts; frequency
should be greater than 58 Hertz.
10. Let the generator run at full rated load tot 20-30
minutes. Listen for unusual noises, vibration or
other indications of abnormal operation. Check
ibr oil leaks, evidence of overheating, etc.
11. When testing tinder load is complete, turn OFF
electrical loads.
12. Set the generator's nmin circuit breakers to their
OFF (or open) positions.
13. Let the engine run at no-load %r a few minutes.
14. Set the AUTO/OFF/MANUAL switch to OFE The
engine should shut down.
2.5 CHECKINGAUTOMATIC
OPERATmON
To check the system for proper automatic operation,
proceed as follows:
1. Set the generator's main circuit breaker to it's
OFF (or open) position.
2. Check that the AUTO/OFF/MANUAL switch is set
to OFE
3. Turn OFF the
utility power supply
to the transfer
switch using the means provided (such as a utility
main line circuit breaker).
4. Manually set the transfer switch to the UTILITY
position, i.e., load terminals connected to the util-
ity power source side.
5. 7him ON the utility power supply to the transfer
swifeh, using the means provided {such as a util-
ity mata line circuit breaker).
G. Set the AUTO/OFF/MANUAL switch to AUTO.
Then set the generator's mata circuit breaker to
its ON (or closed) position. The system is now
ready for autonmtic operation.
7. Turn OFF the
utility power supply
to the transfer
swifeh.
With the AUTO/OFF/MANUAL swifeh at AUTO, the
engtae should crank and start when the utility source
power is turned OFE AAer starting, the transfer
swifeh should connect load circuits to the standby
side. Let the system go through its entire automatic
sequence of operation.
