Connecting the grounding
Pfeiffer Vacuum recommends connecting an appropriate grounding cable to divert applicative interfer-
ence forces.
1. Use the grounding terminal of the turbopump (M4 internal thread).
2. Perform the connection in accordance with applicable local regulations.

Secure the HiCube 300 Eco against twisting
In the case of a sudden blocking of the turbopump rotor, the resulting torque must be taken up via the
pumping station frame by the fixture provided by customer. Anchoring the pumping station is mandatory
in order to secure the pumping station and the vacuum system. For this purpose there are 2 securing
hooks at the sides of the pumping station frame.
1. Always fasten the HiCube 300 Eco pumping station using securing straps to both securing hooks.
2. Fix the securing straps against the securing hook openings and thus against the direction of rota-
tion of the turbopump.
3. Fasten the securing straps at the customer's site such that they are able to withstand loads of up
to 2000 N per fixing point.
4. Ensure that the straps are correctly positioned and tensioned. The loop of each strap must be in
the hollow of the hook.
