OPERATION
TESTING 240VAC SINGLE PHASE
2-1 SETTING UP THE LOAD BANK - Place the load bank in an area free from fuel, oil, or any other flammable
substance. The load bank should be positioned so that any strong wind or air currents will flow with the air
flow of the load bank.
2-2 APPLYING POWER - The load bank should be connected to the power unit to be tested with an output of
240VAC single phase.
Make sure that the power unit is off before connecting the cable to the load bank. Use
L1 (Black), L2 (Red) and N (White) when testing 240VAC single phase circuits. Plug the power cable plug in to
the load bank and connect the L1 cable to L1 on the power unit, the L2 cable to L2 on the power unit and N to
the ground on the power unit.
The meter switch should be in the L1-L2 position. Turn on the output of the
power unit.
2-3 CHECKING THE POWER - check the following:
A. The amber light,
“A” and “B” should be on.
B. The VOLTS should read 240VAC
on “A” and “B” phase.
C. The FREQUENCY should read approximately 60HZ.
D. The AMPS should read 0A.
2-4 APPLYING THE LOAD - If the above steps checked OK, turn the main switch to 208VAC. The fans
should start up and the airflow should be as indicated by the airflow arrow. Next turn on load switch. Add the
load desired with the rate switch.
A. Step 1 is 6.6KW
B. Step 2 is 6.6KW
C. Step 3 is 13.2KW
D. Step 4 is 13.2KW
E. Step 5 is 13.2KW
Total load at 240Vac single phase is 52.8KW
Check to see that the voltage and frequency does not drop beyond acceptable limits under load.
2-5 SHUTTING DOWN -Turn the load and rate switches to off, allow the load bank to cool down before turning
the main switch to off. Turn the power unit off and disconnect the power cable plug.
