Notes
Notes supply information on states requiring particular attention, or
indicate that additional information is available on a specific topic.
For this purpose, the following symbols are used:
CAUTION!
Cautions
are designed to draw your attention to a
particular state of affairs.
Note
A
note
contains or refers you to additional informa-
tion available on the particular topic concerned.
Mains connection
You can use a switch disconnector (with fuses) in the power supply
of the thyristor power converter to disconnect the electrical compo-
nents of the unit from the power supply for installation and mainte-
nance work. The type of disconnector used must be a switch dis-
connector as per EN 60947-3, Class B, so as to comply with EU
regulations, or a circuit-breaker type which switches off the load
circuit by means of an auxiliary contact causing the breaker’s main
contacts to open. The mains disconnector must be locked in its
"OPEN" position during any installation and maintenance work.
EMERGENCY STOP
buttons
EMERGENCY STOP buttons must be installed at each control
desk and at all other control panels requiring an emergency stop
function. Pressing the STOP button on the CDP 312 control panel
of the thyristor power converter will neither cause an emergency
motor stop, nor will the drive be disconnected from any dangerous
potential.
To avoid unintentional operating states, or to shut the unit down in case of
any imminent danger according to the standards in the safety instructions
it is
not
sufficient
to
merely
shut down the drive via signals „RUN“, „drive
OFF“ or „Emergency Stop“ respectively „control panel“ or „PC tool“.
Intended use
The operating instructions cannot take into consideration every
possible case of configuration, operation or maintenance. Thus,
they mainly give such advice only, which is required by qualified
personnel for normal operation of the machines and devices in
industrial installations.
If in special cases the electrical machines and devices are in-
tended for use in non-industrial installations - which may require
stricter safety regulations (e.g. protection against contact by
children or similar) -, these additional safety measures for the
installation must be provided by the customer during assembly.
