Safety of Mains Operated Equipment
This equipment has been designed to meet the safety regulations currently
advised in the country of purchase and it conforms to the safety regulations
specified by use of the CE Mark.
Warning : There are no user serviceable parts inside the equipment. If you should ever
need to look inside the unit, always disconnect the mains supply before removing the
equipment covers.
Voltage Setting Checks
Ensure that the machine operating voltage is correct for your mains power supply by
checking the box in which your Reference Monitor Meter was supplied. The voltage is
shown on the box label. Please note that all Reference Monitor Meters have a universal
power supply, 85-264V AC, 47-63Hz.
Fuse Rating
The Reference Monitor Meter is supplied with a single fuse in the live conducting path
of the mains power input. For reasons of safety it is important that the correct rating and
type of fuse is used. Incorrectly rated fuses could present a possible fire hazard, under
equipment fault conditions. The fuse rating for the Reference Monitor Meter is:
1A 5 x 20mm SB
The active fuse is fitted on the outside rear panel of the unit.
Power Cable and Connection
An IEC power connector is supplied with the Reference Monitor Meter which has a
moulded plug attached – this is a legal requirement. If no moulded plug has been supplied
with your Reference Monitor Meter, please contact your supplier, because an IEC connector
is always supplied from the Sonifex factory.

cable, you should use the following wiring guidelines.
