6.2 Information on operation
When operating the controller, please observe the following notes:
Stop!
• Cyclic connection and disconnection of the controller supply voltage at L1, L2, L3 or +U
G
,
-U
G
may overload the internal input current load:
– Allow at least 3 minutes between disconnection and reconnection.
• During mains switching (L1,L2,L3) it is not important whether further controllers are supplied
via the DC bus.
6.2.1 Switching on the motor side
• Switching on the motor side of the inverter is permissible for emergency switch-off.
• Please note:
– Switching while a controller is enabled may cause the fault indication ”0Cx”
(short-circuit/earth fault in operating case x).
– For long motor cables and operation of controllers with smaller output power, leakage
currents through interfering cable capacitances may cause the fault indication ”OCx”.
– Switching equipment on the motor side must be dimensioned for DC voltages
(U
DC max
= 800 V).
