Warning
The rated current of the connected motor must match the rated drive converter
current, as otherwise motor feeder cable protection is not guaranteed. The
cross–section of the motor feeder cable must be dimensioned for the rated
drive converter current.

Warning
Before commissioning the 611D, the encoder cable must be checked to ensure
that it has no ground faults. If there is a ground fault, uncontrolled movement
could occur for pulling loads.

Note
If a system high voltage test is made, the overvoltage limiting module must be
removed in order to prevent the voltage limiting responding.
When configuring the system, the connection between the voltage limiting cir-
cuit and the central grounding point should be as short as possible and be low
ohmic.
Note
The terminal blocks of the SIMODRIVE 611 modules are exclusively used to
electrically connect that particular module; if they are used for any other pur-
pose (e.g. as handle) this can cause damage to the module.
