OPERATION
TESTING 120VAC 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
120VAC 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 single phase circuits. L1 should be connected to the line out,
L2 should be connected to neutral and the N cable should be connected to the ground of the unit being tested
.
Plug the power cable plug in to the load bank. 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” should be on.
B. The VOLTS should read 120VAC
on “A” 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 on the main switch to 208VAC. The fans
should start up and the airflow should be as indicated by the airflow arrow. Next turn on the load switch. Add
the load desired with the rate switch.
A. Step 1 is 1.7KW
B. Step 2 is 1.7KW
C. Step 3 is 3.3KW
D. Step 4 is 3.3KW
E. Step 5 is 3.3KW
Total load at 120VAC is 13.3KW.
Check to see that the voltage and frequency does not drop beyond acceptable limits under load.
2-5 SHUTTING DOWN - Turn the load switch and rate switches to the off position and 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.
