3.2   EMC regulations

    

To comply with the current EMC regulations, it is necessary to connect the 
lines leading in and out of the head-end station using cable terminals. 

 When mounting the cassette in an STR 19-8 head-end station which is in-

stalled in a 19” cabinet, make sure the connections leading in and out for 
the 19” cabinet are made using cable terminals.

• Insert the required number of cable terminals in the openings provided in the 

head-end station or in the 19” cabinet.

  —>  Cable

 

terminals are not included in the scope of delivery.

 

  

Tighten the nut on the cable terminals until the teeth on the lock washer have 
penetrated the exterior coating and a good connection is made between the 
housing and cable terminal.

3.3  Connecting the cassette

• Connect the HF input cable to the ”
