4.7 DC link connection of frequency inverter with
AEC
WARNING
Dangerous voltage!
When the device is disconnected from power supply, the mains
and DC terminals may still be live for some time. Work on the
device may only be started once the DC link capacitors have
discharged. The time to wait is at least 3 minutes in the case of
sizes 1 through 7 and at least 8 minutes in the case of size 8.
The electrical installation must be carried out by qualified
electricians according to the general and regional safety and
installation directives.
The documentation and device specification must be
complied with during installation.
Before any assembly or connection work, disconnect the
device from power supply.
Check for absence of voltage.
Do not connect inappropriate voltage sources. The nominal
voltage of the device must correspond to the supply voltage.
The devices must be connected to ground potential.
Do not remove any covers of the device while power supply
is on.
CAUTION
Device damage
Unsuitable frequency inverters will be damaged or destroyed if
used in combination with a mains unit.
For the "Sinusoidal feedback" function, IT-ACU/ANG devices
must be used in any case.
For mains and motor connection of an ACU or ANG frequency
inverter, comply with the Operating Instructions of this device.
