Compliance Classifications
The product is designed to the following standards for sale into European markets and will
carry the “CE” mark.
Electromagnetic Conformance (EMC)
The product is designed to comply with the following European standards:
EN50082-1 1992 Electromagnetic Compatibility Generic Immunity Standard
EN55022 1995 Limits and methods of measurement of radio disturbance characteristics of
information technology equipment.
Safety
The product is intended for use in machines that are designed to comply with;
a) EN60335-1, 3rd Edition, Safety of household and similar electrical appliances, Part 1,
General Requirements.”
b) BS3456, Safety of household and similar electrical appliances, Part 1, General
Requirements.
c) BS EN60950 1992, Safety of Information Technology Equipment, including electrical
business equipment.
The product is suitable for use in a class 2 (non-earthed or non-grounded) appliance as
defined in EN60335.
All electrical connections to the acceptor must be rated according to the requirements for
“Accessible SELV” circuits as defined in EN60335.
When used in applications where compliance to BS EN60950:1992 is necessary, the host
machine power supply must additionally meet the requirements for SELV limited power
supplies as defined in BS EN60950. For these applications, the coin mechanism should be
installed so that it is external to any fire enclosure.
Flammability
All major plastic parts will be moulded in materials with a flammability rating of 94 V-2 / IEC
707 FV2 or better. Some small parts are moulded in materials with a flammability rating of
94 HB / IEC 707 FH2.
