There is a big difference between a Surge Suppressor and a good EMS, so I don't know exactly what you have. A Surge Suppressor/Guard will only protect from surges, while a good EMS will protect you from Over/Under Voltage, Surges, Open Grounds and Neutrals, and mis-wired pedestals.
What ever, glad it functioning correctly now.
