Product information for series large current generator:
a) Series large current generator is designed for short time working, so do not allow for a long time working under the rated capacity, in particular must not exceed the rated current running, in order to prevent overheating.
b) For the new installed and long time no using transformer, should use the 1500 megger to measure the coil and coil-to-ground insulation resistance before usE, if the value of the resistor is not less than 0.5 megohms, it can be used. 
c) In use, the boost transformer and operation desk must be grounded, to ensure safety.
d) The boost process should be slowly and evenly, in the process of movement, should avoid excessive vibration during moving . 
e) The contact surfaces of regulator and electrical brush should be kept clean, depending on the circumstances, can use 90% alcohol dipped cotton to wipe.
f) Series large current generator should be stored in a clean, ventilated and dry place.
