Description
WARNING
Danger of electric shock due to high DC voltage in the supply lines (about
DC 900 V).
Severe or fatal injuries.
•
Only use cables provided by SEW‑EURODRIVE.
•
Install the cables according to the instructions.
WARNING
Risk of burns due to hot surfaces. Braking resistors reach a temperature of up to
250 °C under load.
Serious injuries.
•
Select a suitable installation location and observe the minimum clearance.
•
Provide for covers to secure hot surfaces.
•
Install the protection devices according to the regulations.
•
Check the protection devices on a regular basis.
NOTICE
In case of incorrect assignment of the inverters, an overload may occur at the brak-
ing resistor and damage the braking resistor.
Damage to braking resistor.
•
Observe the assignment of the braking resistor to the inverter and the project
planning guidelines.
For regenerative operation, an external braking resistor is connected to MOVIPRO
