Termination technology
Pre–assembled cables save on the assembly time and increase the operational
reliability.

Caution
Servomotors cannot be directly connected to the line supply, and should only
be used with the assigned SIMODRIVE 611 transistor PWM converters.
Please observe the rating plate data and adequately dimension the connecting
cables (tables are included in the Guide), and ensure that these cables are
strain–relieved.
For safety–relevant circuits, it should be checked, for every application,
whether the internal control devices in the drive converter are adequate to elec-
trically isolate it from the line supply.
When carrying–out any work on the system, it should always be in the no–volt-
age condition (powered–down)!
Table 4-1 specifies the permissible current load capability acc. to DIN VDE 0113
Part 1/02.86 “Electrical equipment on industrial machines” for PVC–insulated
cables with copper conductors at an ambient temperature of 40
°
C.
