10.1.6 Connection of additional consumers
It is not permitted to connect additional consumers (e. g. control cabinet fans or air-con-
ditioning units) parallel to the drive controller [2]/regenerative power supply unit in front
of a common power switch (
→ following figure) . When triggering the switch, there is no
connection to the power supply system [1] that represents the power drain and the syn-
chronizing element for the incoming and regenerative unit. The IGBTs will now route the
DC link voltage directly to the consumers. The resulting and almost rectangular "power
supply" voltage supplies a current to the consumers whose strength and shape depends
on their impedance. If the power consumption of the consumers is too low, the DC link
voltage will increase in regenerative operation as well as the output voltage of the re-
generative power supply units. This high voltage can damage all connected units.

NOTICE
Overvoltages can cause irreparable damage to the connected drive controller
[2] and/or the regenerative power supply unit as well as the other loads.
