SECTION 4: INSTALLATION
4.1 Unpacking
Unpack the degausser carefully, and inspect it for signs of physical damage. If damage is
apparent, a claim should be filed with the courier.
4.2 Power Requirements
Check the power supply requirements on the label attached to the back of the equipment
with the available supply. The unit is supplied with a flying 3 wire cable which, when
connected to a properly wired receptacle, earths the unit. It is essential that a proper earth
connection is made to assure safe operation.
CAUTION!
A good electrical ground must be connected to the degausser. The unit must be
connected to the correct power supply. Failure to do so may result in permanent
damage.

IMPORTANT INSTRUCTION
The mains supply outlet socket should be close to the installed equipment and fully
accessible.
NOTE:
Degausser Current Consumption
The degaussing coils are powered as part of a tuned resonant circuit. This allows quite
high circulating currents to be generated within the degaussing coils, with minimal current
consumption from the mains voltage supply. However, this technique requires that the
waveform of the supply voltage contains minimal harmonic distortion. A distorted waveform
will result in an increase in current consumption. In extreme cases excessive current will
trip the circuit breaker making it necessary to use a mains filter to remove the distortion
and reduce the current consumption.
The typical current consumption figures provided in this manual are when powered from a
supply with minimal distortion. Any increase in current consumption due to a distorted
waveform will have minimal effect on the degausser performance; however, excessive
current consumption should be avoided for obvious reasons. In the event of unexplained
high currents, please consult your supplier.
