Warning
Only qualified personnel should operate the HarmonicGuard Active filter with the door open. Failure
to follow standard safety procedures may result in death or serious injury. Do not attempt any work
on a powered filter converter.
The HGA contains high voltages and capacitors. Wait at least five minutes after disconnecting power
from the converter before you attempt servicing. Check for zero voltage between all terminals to the
converter. Be aware everything ahead of the circuit breaker will still be energized.
