High voltages in the intermediate circuit
Note that even after the power supply unit has been switched off high volt-
ages may occur in the intermediate circuit of the complete system that can
cause serious injuries.
→ Wait until the intermediate circuit is fully discharged before cutting the
connections of the intermediate circuit ("capacitor discharge").
→ Take the following steps before working on the device or on the inter-
mediate circuit:
→ Disconnect the power supply unit definitely from the mains supply.
→ Wait until the discharge time of the of the DC link capacities has ex-
pired. It is longer than 4 minutes.
→ Ensure by measuring that the intermediate circuit is fully discharged.
→ Disconnect the intermediate circuit connections from the power sup-
ply.
→ Also consider general safety instructions before you continue working
on the device.
