General warning
The DMS contains dangerous voltages
when connected to line voltage. Only a
competent electrician should carry out the
electrical installation. Improper installation of the motor
or the DMS may cause equipment failure, serious
injury or death. Follow this manual as well as national
and local rules and safety regulations.
■
Safety regulations
1. The DMS must be disconnected from the mains
if repair work is to be carried out.
2. The [COASTING STOP INVERSE] command
applied to the DMS does not disconnect the
equipment from the mains and thus is not to
be used as a safety switch.
It is the responsibility of the user or the
person installing the DMS to provide proper
grounding and branch circuit protection in
accordance with national and local regulations.
■
Warning against unintended start
1. The motor can be brought to a stop by means
of digital commands, bus commands or a local
stop, while the DMS is connected to the mains. If
personal safety considerations make it necessary
to ensure that no unintended start occurs, these
stop functions are not sufficient.
2. A motor that has been stopped may start if faults
occur in the electronics of the DMS.
■
Avoiding DMS damage
Please read and follow all instructions in this manual.
Electrostatic Precaution; Electrostatic
discharge (ESD). Many electronic
components are sensitive to static
electricity. Voltages so low that they cannot be
felt, seen or heard, can reduce the life, affect
performance, or completely destroy sensitive
electronic components. When performing service,
proper ESD equipment should be used to prevent
possible damage from occurring.
