    : Do not feed the EPM 2000’s auxiliary power supply terminals with a voltage greater than the rating marked on the label. The EPM 2000 will be permanently damaged and GE’s Warranty shall be void. 5.2. Potential Transformers and Current Transformers Large electrical installations have high voltages and currents which may exceed the direct connection rating of the meter.
