Applying the test voltage to the R and G terminals will OTE: Program for PDA damage the SE-330HV and the ER sensing resistor. The V TRIP LEVEL is the trip voltage at terminal N, not terminal R. * Available at www.startco.ca.
The connection of the current-transformer secondary to the SE-330HV is not polarity sensitive. c) Verify that the system is correctly grounded and that alternate ground paths do not exist that bypass the current transformer.
