EMC Directive 89/336/EC (Disclaimer)
Please note that the item to which the enclosed application data refer is designed to be used as a
component in another finished good, and is not intended to be placed on the market or brought into
service independently. The system integrator using this item must assume responsibility for
Electro-Magnetic Compatibility (EMC) between this item and its environment, both for emissions and
immunity/susceptibility.
Particular attention should be paid to the wiring connections between the item and the power supply,
data source and other parts of the user's system in case special shielding and/or cable layout is
required to meet applicable EMC criteria.
A104B Series Printer Controller Boards
To assist OEM customers, we have carried out traceable pre-compliance tests on our most popular
Ap24 printer, which indicate that the printer itself is unlikely to prevent EMC compliance of the
customer's equipment, as follows:
Since the A104B is DC powered and will only be electrically connected within an OEM equipment,
conducted emissions and immunity are not relevant, and we consider that the A104B falls outside
the scope of the Regulations in these regards.
When fitted in an earthed steel case and connected to an internal data source and power supply,
the A104B may be expected to comply with the requirements of the EMC Directive in respect of
radiated emissions and immunity;
When fitted with an earthing wire to the mechanism, the A104B may also be expected to comply
with the requirements in respect of electrostatic discharge (ESD).
