Warning
Unauthorized opening of the converter
voids the warranty.
Before opening the converter, always dis-
connect it from the mains and the pump!
Before disconnecting any cables make sure
that the converter is switched off and the
pump has come to a standstill.
When applying external voltage in excess
of 42 V to terminals of the device, observe
local safety regulations!
Unauthorized device conversion and modi-
fications are prohibited for safety reasons.
Warning
The rotor has to be changed after 40,000
hours of operation or after 5000 starts/
stops.
Due to high-speed and temperature, the
service life of the rotor is limited.
If the rotor is changed too late, it may be
destroyed. Thus in the flange mounts high
forces and torque conditions can occur.
The mounting screws for the pump may
be torn off.
When using clamped flange
connections at the housing or with compo-
nents above the housing, sudden twisting of
the entire pump can be experienced.
The pump’s operating hours are displayed at the fre-
quency converter (see Sectiont 4.3.2 ).
Only the Leybold service can change the rotor.
Please keep this Operating Instruction for future reference.
