8 SAFETY.
Before handling any device in the filter disconnect the supply upstream. The filter does not have any
main switch. Switch must be placed at the line head.
Even when the bank is disconnected, there still may be voltage in the capacitors. Therefore, after
having removed the supply voltage, wait for 3 minutes and then short circuit them and earth the
terminals or output cables on each capacitor.
