4) Operation
Please contact Mosebach Manufacturing if you are planning on operating the load bank
in ambient temperatures above 46 ºC.
Ambient plus heat generated by the resistive elements can cause electrical components
to possibly malfunction.
a. Pre-Start Up
i. Check housekeeping in the operational area and correct all unsafe
conditions.
ii. Failure to do this may result in debris being blown around and may
cause a fire hazard.
iii. Check the switch panel and move all switches to the OFF position.
iv. Position the load bank so that air will flow freely into the intake and out of
the exhaust port.
v. All air intakes and exhaust ports must be clear.
b. Start Up
i. Connect the grounding Cam Lock on the unit directly to a known earth-
ground.
ii. Connect all
de-energized
load power to Cam Lock connections on the
unit.
iii. Energize the load power source with an acceptable voltage.
iv. Turn the MAIN on/off power switch to the ON position. The unit will only
run if an acceptable voltage is supplied. The meter, green Main Power
