Safety Information
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
specied 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 was supplied. The voltage is shown
on the box label. The available voltage settings are 115V, or 230V. Please note that all
Reference Monitores are either switchable between 115V and 230V, or have a universal
power supply.
Fuse Rating
The Reference Monitor 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 re hazard, under equipment
fault conditions. The fuse rating for the Reference Monitor is:
230 or 115 V operation - 2A 5 x 20mm SB
The active fuse is tted on the outside rear panel of the unit.
Power Cable and Connection
An IEC power connector is supplied with the Reference Monitor which has a moulded plug
attached – this is a legal requirement. If no moulded plug has been supplied with your
Reference Monitor, please contact your supplier, because an IEC connector is
always supplied from the Sonifex factory.
If for any reason, you need to use the Reference Monitor with a dierent power cable, you
should use the following wiring guidelines.
Wire Colour Connection
Green, or green and yellow Earth (E)
Blue, or black Neutral (N)
Brown, or red Live (L)
Fig B: Power Connections
Connect the equipment in accordance with the connection details and before applying
power to the unit, check that the machine has the correct operating voltage for your mains
power supply.
Important Note : The terminal marked on the rear panel must be earthed.

Reference Monitors User Handbook v
Ordering the Correct Mains Lead
When ordering a Reference Monitor from Sonifex, it is helpful if you can specify your
required operating voltage and mains lead. After the product code add:
UK, for 230V, UK 3 pin to IEC lead
EC, for 230V, European Schuko 2 pin to IEC lead
US, for 115V, 3 pin to IEC lead
AU for 230V, Australasian 3 pin to IEC lead
Fig C: Mains Lead Table
E.g. order RM-2S4 UK for a UK IEC lead to be supplied.
Installation Information
Atmosphere
The units should be installed in an area that is not subject to excessive temperature
variation (<0°C, >50°C), moisture, dust or vibration.
Electromagnetic Radiation
The cover is connected to earth by means of the xing screws. It is essential to maintain
this earth ground connection to ensure a safe operating environment and provide
electromagnetic shielding.

WEEE & RoHS Directives - Sonifex Statement
The Waste Electrical and Electronic Equipment (WEEE) Directive was agreed on
13 February 2003, along with the related Directive 2002/95/EC on Restrictions
of the use of certain Hazardous Substances in electrical and electronic
equipment (RoHS).
The Waste Electrical and Electronic Equipment Directive (WEEE) aims to minimise the
impacts of electrical and electronic equipment on the environment during their life times
and when they become waste. It applies to a huge spectrum of products. It encourages
and sets criteria for the collection, treatment, recycling and recovery of waste electrical and
electronic equipment. All products manufactured by Sonifex Ltd have the WEEE directive
label placed on the case. It gives a contact for individuals who are unsure about the correct
procedure when the product has reached its “end of use”.
Sonifex Ltd will be happy to give you information about local organisations that can
reprocess the products, or alternatively all products that have reached “end of use”can be
returned to Sonifex and will be reprocessed correctly free of charge.
Sonifex Ltd has phased out the use of certain hazardous substances identied in the
European Union’s Restriction of Hazardous Substances (RoHS) directive. The RoHS
directive limits the use of certain hazardous substances currently used in EEE manufacture,
including lead, mercury, cadmium, hexavalent chromium, and halide-containing
compounds PBB (polybrominated biphenyl) and PBDE (polybrominated diphenyl ether).
Elimination of these substances will result in more environmentally friendly recycling
of electronic equipment. For the products which Sonifex manufacture, the main area
where products were aected was in the use of lead for manufacturing and assembling
electronics circuit boards.
Sonifex Ltd practices lead-free (LF) manufacturing processes. LF solder is used on the
surface-mount PCB manufacturing processes and for hand soldering. The printed circuit
boards (PCBs) used are either gold plated, or immersion tin plated, both of which use no
lead. Historically the PCBs were hot air solder levelled (HASL) PCBs which used tin/lead
based solder.
The manufacturing processes include the assembly of purchased components from
various sources. Product is oered as RoHS compliant, or LF, only after sucient evidence
is received from the component manufacturers that their components are RoHS compliant.
Sonifex Ltd relies solely on the distributor, or manufacturer, of the components for
identication of RoHS compliance. Thus whilst every eort is made to ensure compliance,
Sonifex Ltd makes no warranty, or certication, or declaration of compliance concerning
said components.
Sonifex Ltd denes “Lead Free” as pertaining to any product, which has been manufactured
by Sonifex Ltd using components which have been declared by the manufacturers as
“Lead Free”. All statements by Sonifex Ltd of RoHS compliance are based on component
manufacturer documentation.
