2 Safety Notes
2.1 Bus systems
A bus system makes it possible to adapt frequency inverters to the particulars of the ma-
chinery within wide limits. As with all bus systems, there is a danger of invisible, external
(as far as the inverter is concerned) modifications to the parameters which give rise to
changes in the unit behavior. This may result in unexpected, though not uncontrolled,
system behavior.
2.2 Safety functions
MOVIDRIVE
®
B and MOVITRAC
®
B inverters may not perform any safety functions
without higher-level safety systems. Use higher-level safety systems to ensure protec-
tion of equipment and personnel. For safety applications, ensure that the information in
the publication "Functional safety for MOVITRAC
®
B" is observed.
2.3 Hoist applications
MOVIDRIVE
®
B and the MOVITRAC
®
B are not designed for use as a safety device in
hoist applications.. Use monitoring systems or mechanical protection devices as safety
equipment to avoid possible damage to property or injury to people.
2.4 Disposal
Observe the applicable national regulations.
Dispose of the following materials separately in accordance with the country-specific
regulations in force, as:
