Check Manual Transfer Switch
Operation
Refer to the Manual Transfer Operation section of the
owner’s manual for procedures.
Electrical Checks
Proceed as follows to complete electrical checks:
1. Verify generator is OFF.
2. Set the generator main line circuit breaker (genera-
tor disconnect) to OFF (OPEN).
3. Turn off all circuit breakers/electrical loads that will
be supplied by the generator.
4. Turn on the utility power supply to the transfer
switch using the means provided (such as a utility
main line circuit breaker).
5. Use a calibrated AC voltmeter to check utility
power source voltage across transfer switch termi-
nals N1 and N2. Nominal line-to-line voltage
should be the output voltage selected during instal-
lation (e.g. 220 VAC). If voltage is not correct, verify
AC output and wiring from utility source to N1 and
N2 lugs at transfer switch.
6. Switch OFF the utility power supply to the transfer
switch when certain that utility power supply volt-
age is compatible with transfer switch and load cir-
cuit ratings.
7. Push the MANUAL mode button on the generator
panel. The engine will crank and start. Record
cranking gas pressure: ______________.
8. Let the engine warm up for approximately five min-
utes to allow internal temperatures to stabilize.
Then set the generator MLCB (generator discon-
nect) to ON (CLOSED). Record running gas pres-
sure: ______________.
9. Connect a calibrated accurate AC voltmeter and a
frequency meter across transfer switch terminal
lugs E1 and E2. Voltage should be the output volt-
age selected during installation ± 2V (e.g. 218-222
VAC) at a frequency of 49.5–50.5 Hz. If voltage is
not correct, verify that the MLCB (generator dis-
connect) is closed and verify AC output and fre-
quency (Hertz or Hz) at the MLCB. Also verify wir-
ing from generator to E1 and E2 lugs at transfer
switch.
10. Verify wiring from generator to E1 and E2 at trans-
fer switch.
11. Set the generator main line circuit breaker (genera-
tor disconnect) to OFF (OPEN).
12. Press the generator OFF mode button. The engine
will shut down.
NOTE: It is important not to proceed until certain that the
generator AC voltage and frequency are correct and
within the stated limits.
Generator Tests Under Load
Proceed as follows to test the generator set with
electrical loads applied:
1. Verify the generator is off.
2. Turn OFF all breakers/electrical loads that will be
powered by the generator.
3. Turn OFF the utility power supply to the transfer
switch, using the means provided (such as a main
line utility breaker).
4. Manually set the transfer switch to STANDBY, i.e.,
load terminals connected to the generator’s E1/E2
terminals. The transfer switch operating lever
should be down.
5. Press the generator MANUAL mode button. The
engine will crank and start immediately.
6. Verify gas pressure while cranking. Record crank-
ing gas pressure: ______________.
7. Allow the engine to stabilize and warm up for a few
minutes.
8. Verify gas pressure while running. Record running
gas pressure: ______________.
9. Set the generator main line circuit breaker (genera-
tor disconnect) to ON (CLOSED). Loads are now
powered by the standby generator.
10. Turn on the circuit breakers/electrical loads that are
powered by the generator one by one.
11. Connect a calibrated AC voltmeter and a frequency
meter across terminal lugs E1 and E2. Voltage
should be the approximate output voltage selected
during installation, and frequency should be
approximately 50 Hz. If the voltage and frequency
are rapidly dropping as the loads are applied, the
generator may be overloading, or there may be a

DANGER
Electrocution. Do not manually transfer under load.
Disconnect transfer switch from all power sources
prior to manual transfer. Failure to do so will result
in death or serious injury, and equipment damage.

DANGER
Electrocution. High voltage is present at
transfer switch and terminals. Contact with live
terminals will result in death or serious injury.
