6) 

OVERCURRENT AND SHORT CIRCUIT PROTECTION 

Remote  overload  protection  is  required.  (see  Fig.  7).  [

Integral  solid  state  short  circuit  protection  does  not  provide 

branch  circuit  protection.  Branch  circuit  protection  must  be  provided  in  accordance  with  the  Manufacturer 
Instructions, National Electrical Code and any additional local code

]. 

The protection devices shown infigure 7a and figure 7b must include a branch fuse type: LP-CC-8 by COOPER 
BUSSMAN LCC or equivalent. [

Suitable for Use On A Circuit Capable Of Delivering Not More Than 5000 Arms 

Symmetrical Amperes, 79 Vdc Maximum for all models when protected by semiconductor fuses model LP-CC-8 by 
COOPER BUSSMAN LCC.

7) 

ELECTRO-MAGNETIC INTERFERENCE 

Drive  and  all  related  cabling  are  source  of  E.M.  interference  (conducted  and  radiated).  In  order  to  comply  to  directive 
2004/108/CE  and  related  standards  (EN  61800-3)  installation  has  to  be  done  according  to  schematics  in  Fig  7  and 
following indications: 

 

 

Locate drives, power supply, transformer and related cables inside the same enclosure, which has to be hermetic 
to electromagnetic fields. 

 

Interpose a filter between the transformer primary and the main (CORCOM mod. 6VDK1). Locate the filter near 
the supply entrance. Use only shielded cable (outside the enclosure) for connecting motor and drive. 

 

Connection made to Protective Earth terminal (PE), shown in Fig.7, must be short and have the lowest possible 
inductance. 

 

Use a supply transformer with a metal shield between primary and secondary winding and connect this shield to 
earth. 

8) 

FORCED COOLING 

According to operating conditions (ambient temperature, current setting, duty-cycle) forced cooling can be necessary. The 
most sure method to evaluate if this need exists or not is to measure temperature of the drive heatsink; if this temperature 
is greater than 65 - 70 °C in the most unfavourable working conditions, you need a forced cooling to obtain a reasonable 
long life from drive.
