  If your DSPM Inverter doesn’t operate, with no lights or warning sounds, here are a few things to check: * First, ensure that the input power source is available and the main input circuit breaker is on. * Next, verify that the Emergency Lighting Inverter System input circuit breaker is also on. * Make sure you are pressing the “ON” button for at least 1 second. * Finally, turn off the Inverter and remove all load to check for output short circuits or overloads.
