CAUTION
Proper grounds, disconnecting devices (e.g. fuses) and other safety devices and their location are the
responsibility of the user and are not provided by WATT Drive GmbH
CAUTION
DANGEROUS VOLTAGE EXISTS UNTIL THE POWER LIGHT ON THE DIGITAL OPERATOR IS OFF.
CAUTION
Rotating shafts and electrical potentials above ground level can be hazardous. Therefore it is strongly
recommended that all electrical work conform to the national electrical codes and local regulations.
Installation, maintenance and alignment should be performed by qualified personnel only.
Factory recommended test procedures included in this instruction manual should be followed. Always
disconnect electrical power before working on the unit.
WARNING
a) Any motor used must be of suitable rating.
b) Motors may have hazardous moving parts so that suitable protection must be provided in
order to avoid injury.
CAUTION
Alarm connections may have hazardous live voltages even when the inverter is disconnected. In case of
removing the front cover for maintenance or inspection, confirm that incoming power for alarm connections is
surely disconnected.
CAUTION
Main terminals or other hazardous terminals for any interconnection (terminals for connecting the motor,
contact breaker, filter etc.) must be inaccessible in end installation.
All of the above instructions, together with any other requirements, reccommendations,
and safety messages highlighted in this manual must be strictly complied with.

WARNING
This equipment should be installed, adjusted and serviced by qualified personnel familiar with
construction and operation of the equipment and the hazards involved. Failure to observe this
precaution could result in bodily injury.
When using L2000 series inverters in EU countries, the EMC directive 89/336/EEC must be observed. To
satisfy the EMC directive and to comply with the standard, the following provisions should be obeyed:
A) Environmental conditions for the inverter:
•
Ambient temperature: -10°C to 40°C.
•
Relative Humidity: 20% to 90% (no dew condensation)
•
Vibrations: max. 5,9m/s
2
(0.6 g) at 10–55Hz.
•
Location: 1000 meter or less altitude, indoors (no corrosive gas or dust).
B) The power supply to the L2000 inverter must conform to the conditions stated below. If one of
the conditions mentioned is not satisfied then an appropriate L2000 AC reactor will have to be
installed.
•
Voltage fluct/-10% or less
•
Voltage unb/-3% or less
•
Frequency var/-4% or less
