Shutdown
Voltage from charged capacitors can still be present at the live components or power connections after disconnection from the supply voltage. Observe the following information to avoid electric shock and risk of injury:
WARNING
The energy storage units are still charged after the device has been switched off.
Severe or fatal injuries from electric shock.
The energy storage units must be discharged before you perform any work on the device. Only electrically skilled persons are permitted to discharge and short-circuit the energy storage units. Information about this can be found in the documentation "EKD-003 Discharge unit and Drive Power Solutions MOVI-DPS®".
WARNING
With the MDP92A on the AC grid, voltage is present between PE and DC link even in deactivated state.
Severe or fatal injuries from electric shock.
All work on the DC link may only be carried out after complete disconnection from the grid.
- Prior to any electric work, the energy storage units must be discharged using the discharge unit from SEW‑EURODRIVE or the braking resistor.
- Observe the hazard symbols on the product.
- Disconnect the device from the grid.
After discharging the external energy storage units, the system must be protected against recharging with a short circuit.
