Problem Description:

Auxiliary port does not function on GP-ISW-R.  Customers are attempting to turn inverter off by applying 12 VDC to the remote.  Feature is not working




Regarding to the Aux. Port on the GPISW-R-12, we have found the resistor value is incorrect in location R30.

Current resistor value is 47K5

Correct resistor value should be 18K2



Replace resistor.




Resistor needs to be replaced and customers unit replaced once testing is complete.  Future orders should not be affected.
