Mains fuse – maximum number of drive controllers
Multiple drive controllers with the power can be connected via a common mains
fuse. The size of the mains fuse as well as the mains input current of the drive
controllers that are supplied with power correspond to that of a single drive
controller.
To prevent damage to the safety fuse, the number of possible drive controllers
on a common mains fuse is limited as follows:
• Size 0 Maximum 4 drive controllers,
• Size 1 Maximum 2 drive controllers,
• Size 2 Maximum 5 drive controllers,
• Size 3 Maximum 2 drive controllers.
NOTICE
Material damage!
To ensure uniform distribution of the charge current to all the drive controllers
supplied with AC power, all fuses must be closed when the supply voltage is
turned on.
To ensure that the input rectifier is not overloaded in case a fuse fails, the
evaluation of phase monitoring of the drive controllers that are supplied with AC
power must result in the entire compound DC link system being disabled.
4.10.4 Power contactor
All drive controllers supplied with power must be connected with the mains
voltage via a common contactor. Make certain to observe the instructions in
7.3.9 X30: Quick DC-Link, braking resistor.
NOTICE
Material damage!
Use only one contactor!
If multiple contactors are used, the charge resistors of the drive controllers will
be damaged by the scattering of switching times that will occur.
