8.2 Safety instructions for the Voltage Sensing Module (VSM10)
NOTICE
Destruction of the VSM10 as a result of incorrectly performed voltage measurements
If the voltage measurement is carried out incorrectly, the VSM10 can be destroyed as a result
of the high voltage stress across the insulating clearance.
• When using long motor cables, it is not permissible that the output voltage of the Motor
NOTICE
Destruction of the VSM10 as a result of a terminal assignment which is not permissible
The VSM10 has two terminal strips, X521 and X522, to sense the three-phase line supply
voltage. A terminal assignment which is not permissible results in the module being destroyed.
• Use just one of the two terminal strips.
• Only connect voltages to terminal strip X521 up to a maximum 100 V (phase-to-phase) via
• Only connect voltages to terminal strip X522 up to a maximum 690 V (phase-to-phase)
NOTICE
Damage through use of incorrect DRIVE-CLiQ cables
The use of incorrect or unreleased DRIVE-CLiQ cables can cause damage or functional faults to
devices or the system.
• Only use suitable DRIVE-CLiQ cables that have been released by Siemens for the particular
Note
Malfunctions due to polluted DRIVE-CLiQ interfaces
Malfunctions can occur in the system through the use of polluted DRIVE-CLiQ interfaces.
• Cover unused DRIVE-CLiQ interfaces with the supplied blanking covers.
Note
Malfunctions when using various generations of the VSM10 with parallel infeed
When connecting infeeds in parallel, only Voltage Sensing Modules of the same generation may
be used (either 6SL3053-0AA00-3AA0 or 6SL3053-0AA00-3AA1), as otherwise malfunctions
can occur.
