DCS 500 User Manual

 

 
 

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: 
 

 

Cautions are designed to draw your attention to a 
particular state of affairs. 

 

A note contains or refers you to additional informa-
tion available on the particular topic concerned. 
 

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 cir-
cuit 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 must be installed at each control desk 
and at all other control panels requiring an emergency stop func-
tion. Pressing the STOP button on the CDP 31x control panel of the 
thyristor power converter will neither cause an emergency motor 
stop, nor will the drive be disconnected from any dangerous poten-
tial. 
 

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 intended 
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 instal-
lation must be provided by the customer during assembly.
