 Stop!
No device protection if the mains voltage is too high
The mains input is not internally fused.
Possible consequences:
ƒ Destruction of the device if the mains voltage is too high.
Protective measures:
ƒ Observe the maximally permissible mains voltage.
ƒ Fuse the device correctly on the supply side against mains
fluctuations and voltage peaks.
 Danger!
Device damage
The installation backplane can be damaged by current overload.
Possible consequences:
ƒ Damage of the DC−bus installation
Protective measures:
ƒ The maximum currents must not be exceeded:
– Current load of the conductors in the installation backplane:
57 A
– Current load of the terminal X111 (right part, +UG/−UG): 50 A
ƒ In DC−bus systems, currents from drives in generator and motor
mode must be considered in the calculation.
