SAFETY

All high performance filters contain capacitors which will store charge even after the power has been removed from the filter. All ac filters listed are fitted with internal discharge resistor networks. These are intended to discharge the capacitors to a safe level within two seconds of switching off the power.

As an added precaution, after removing the power, filter terminals should always be shorted to earth (filter case) and to each other, before touching. A good low impedance earth connection must be  made to the filter.
