Install operating fluid reservoir
1. Insert the new capillary rods using tweezers.
2. Insert the operating fluid reservoir up to the stop in the pump base.
– When doing so, do
not
exert pressure on the operating fluid reservoir.
3. Insert the O-ring in the groove in the pump base.
4. Mount the housing cover.
5. Tighten the housing cover with the Torx screws.
– torque:
0.8 Nm
.
6. Screw the rubber-metal pad into the pump base.
7.4 Replace the electronic drive unit
NOTICE
Damage to the turbopump and electronic drive unit due to improper disconnection of compo-
nents
Even after the mains power is switched off, the turbopump continues to deliver electrical energy dur-
ing its run-down period. If the turbopump and electronic drive unit are disconnected prematurely,
there is the risk of body contact and consequently the destruction of electronic components.
► Never disconnect the turbopump and electronic drive unit from each other if power is still con-
nected or if the rotor is running.
► Monitor the turbopump rotation speed via the parameters available in the electronic drive unit
(e.g.,
[P:398]
).
► Wait until the turbopump comes to a standstill (rotation speed f=0).
NOTICE
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".
