7.4 Replacing electronic drive unit
Damage to the vacuum pump and electronic drive unit due to improper disconnection of com-
ponents
Even after the power supply has been switched off, the vacuum pump continues to deliver electrical
energy during its run-down period. If the vacuum pump and electronic drive unit are disconnected
prematurely, there is the risk of body contact and consequently the destruction of electronic compo-
nents.
► Never disconnect the vacuum pump and electronic drive unit from each other if power is still con-
► Monitor the rotation speed via the parameters available in the electronic drive unit (e.g. [P:398]).
► Wait until the vacuum pump comes to a standstill (rotation speed f = 0).
Property damage from electrostatic discharge
Neglecting the electrostatic hazard for electronic components results in their damage or destruction
► Implement ESD safety measures at the workstation.
► Observe EN 61340 "Protection of electronic devices from electrostatic phenomena".
