Finally, some consideration should be given to the earthing arrangement of the system
at the centre of which are the console and the CPS2000 (and any other Soundcraft
power supply units). The console chassis is earthed, through the mains earth, via the
power supply. When rack-mounting the CPS2000(and any other Soundcraft power
supply units) care should be taken to avoid any possible ‘ground loops’ in the system
which would introduce audible hum to otherwise clean audio signals. Ground loops
may occur where signal processing equipment, patched to the console, has its signal
earth commoned to the equipment chassis. The ground loop is formed if this chassis
and the power supply chassis are in electrical contact through the fixing rails they
share in the rack. To avoid this situation, standard isolating washers may be employed
when fixing the power supply (or supplies) or any other unit into the rack.

EARTHED. Under no circumstances should the mains
earth be disconnected from the CPS2000 power supply
unit.
