Studer OnAir 3000 Operating Instructions Manual page 7

Class I Equipment (Mains Operation)
Class III Equipment (Battery Operation up to 60 VDC)
B4 Electromagnetic Compatibility (EMC)
Should the equipment be delivered without a matching mains cable, the
latter has to be prepared by a trained person using the attached female plug
(IEC 320 / C13 or IEC 320 / C19) with respect to the applicable regulations
in your country.
Before connecting the equipment to the AC power outlet, check that the local
line voltage matches the equipment rating (voltage, frequency) within the
ad missible tolerance. The equipment fuses must be rated in accordance with
the specifications on the equipment.
Equipment supplied with a 3-pole appliance inlet (protection conforming to
class I equip ment) must be connect ed to a 3-pole AC power outlet in such a
way that the equipment ca binet is connected to the protective earth.
For information on mains cable strain relief, please refer to Appendix 2.

Equipment of this protection class must be earthed using the provided earth
terminal if one or more external signals are connected to the unit (see expla-
nation at the beginning of this paragraph).
The unit conforms to the protection requirements relevant to electromagnetic
phenomena that are listed in guidelines 89/336/EC and FCC, part 15.
• The electromagnetic interference generated by the unit is limited in such
a way that other equipment and systems can be operated normally
• The unit is adequately protected against electromagnetic interference so
that it can operate properly
The unit has been tested and conforms to the EMC standards of the speci-
fied electromagnetic environment, as listed in the following declaration.
The limits of these standards ensure protection of the environment and cor-
responding noise immunity of the equipment with appropriate probability.
However, a professional installation and integration within the system are
imperative prerequisites for operation without EMC problems.
For this purpose, the following measures must be followed:
• Install the equipment in accordance with the operating instructions. Use
the supplied accessories
• In the system and in the vicinity where the equipment is installed, use only
components (systems, equipment) that also fulfill the EMC standards for
the given environment
