A trouble-free and safe operation of the COMBIVERT R6 is only guaranteed
when the connection instructions below are strictly followed. Incorrect opera-
tion or damage may result from incorrect installation:
• Pay attention to mains voltage.
• Install power cables and control cables separately (>15 cm separation).
• Use shielded / twisted control lines. Lay shield at one side to COMBIVERT
R6-S to PE !
• Only use suitable circuit elements to control the logic and analog inputs,
whose contacts are rated for extra-low voltages.
• Housing of the COMBIVERT R6 must be well earthed. Screens of larger
power cable must be directly and securely attached to both the inverter PE
terminal and the motor ground terminal (remove paint) !
• Ground the cabinet or the system earth star point with the shortest connec-
tion to mains earth. (avoid earth loops)
• Use exclusively the line commutation throttle specified by KEB.
• The average value of the supplied DC current may not exceed the maxi-
mum DC current.
• If several frequency inverters are connected to the COMVIBERT R6-S the
max. permissible DC link capacities of all connected frequency inverters
must be considered during supply operation (see technical data).
The COMBIVERT R6 can be adjusted by such way that the inverter restarts
automatically after an error case (e.g. phase failure). System design must take
this into account, if appropriate, and additional monitoring or protective fea-
tures added where necessary.
The COMBIVERT R6 is not short-circuit proof at the power supply input ! A con-
ditional protection at the supply input is possible if the I
with a gR fuse. Short-circuit protection at the DC output is ensured by internal
or external aR or gR fuses.
