S Should differences in potential occur between the
machine rotor and stator because of unchecked leak
age, for example, this can usually be overcome by
connecting the rotor definitively to ground, e.g. with a
wire loop. The stator must be connected to the same
(ground) potential.

Connector pin assignment
The stator housing has two 7‐pin plugs, an 8‐pin plug and
a 16‐pin plug.
The supply voltage connections and shunt signal connec
tions of plugs 1 and 3 are each electrically intercon
nected, but are protected against compensating currents
by diodes. There is also a self‐resetting fuse (multifuse)
to protect the supply connections against overload by the
stator.
Notice
Torque flanges are only intended for operation with a DC
supply voltage. They must not be connected to older
HBM amplifiers with square‐wave excitation. This could
destroy the connection board resistors or cause other
faults in the amplifiers.
