3.6.10 Load Sharing
Terminal No.
88, 89
The connection cable must be shielded and the max. length from the adjustable frequency drive to the DC bar is limited to 82 ft [25 m].
Load sharing enables the linking of the DC intermediate circuits of several adjustable frequency drives.
Please note that voltages up to 1099 V DC may occur on the terminals.
Load sharing calls for extra equipment and safety considerations. For further information, see load sharing instructions MI.50.NX.YY.
Please note that a line power disconnect may not isolate the adjustable frequency drive due to DC link connection
3.6.11 Shielding against Electrical Noise
Before mounting the line power cable, mount the EMC metal cover to ensure best EMC performance.
NOTE: The EMC metal cover is only included in units with an RFI filter.
