FUSES: Two 20x5mm, 1Amp slo-blo fuses (T 1A L 250V) on front panel.
CAUTION: for continuos protection against fire, replace with same type and rating fuse.
P+ fuse for the independent precision phantom network supply.
V± fuse for the independent bipolar amplifier supply.
GROUND LIFT: A toggle switch on the front panel connects/disconnects the DC
common/signal ground from the PS34’s AC Safety Ground. This may alleviate ground
‘loop’ problems under certain interconnect configurations. The DC common is ‘lifted’
when the switch is in the up position.
Please note that the PS34’s chassis is always connected to the third pin safety
ground of the AC plug. If the PS34 is mounted in the same rack with other devices, their
chassis grounds will be connected via the rack rails, defeating the ground lift switch’s
function.
