Class I Equipment (Mains Operation)
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
(IEC320/C13 or IEC320/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 admissible 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 equipment)
must be connected to a 3-pole AC power outlet so that
the equipment cabinet is connected to the protective earth.
For information on mains cable strain relief please refer to Appendix 2.

Class III Equipment (Battery Operation up to 60 V
DC
)
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 ex-
planation at the beginning of this paragraph).
B4 Electromagnetic Compatibility (EMC)
The unit conforms to the protection requirements relevant to electromag-
netic 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 stan-
dards for the given environment.
• Use a system grounding concept that satisfies the safety requirements
(class I equipment must be connected with a protective ground conduc-
