Connecting temperature sensors
Temperature sensors may be connected only to intrinsically safe circuits with certified
evaluation devices. The maximum permissible input currents and powers according to the EU
type-examination certificate may not be exceeded. This can otherwise result in damage.
● If shielded, intrinsically safe temperature sensors are fitted or mounted, they must be
connected using the blue connecting terminals. The cable shield is grounded just once;
multiple grounding is not permitted.
6.9.5 Finishing connection work
1. Before closing the terminal box, please check that:
– The electrical connections in the terminal box have been made in accordance with the
specifications above and tightened with the correct tightening torque.
– The machine is connected in such a way that it rotates in the direction specified.
– The inside of the terminal box is clean and free of any cable debris, dirt and foreign
bodies.
– All of the seals and sealing surfaces of the terminal box are intact and in a good condition.
– Any unused cable entries are sealed with glued-in ferrous or certified sealing elements.
The sealing elements can only be removed with a tool.
– The connecting cables are laid in an open arrangement, so that the cable insulation
cannot be damaged during operation.
2. Close the terminal box with the cover fixing screws, see chapter Technical data (Page 155).

NOTICE
Material damage caused by an excessively high supply voltage
Material damage can occur if the supply voltage is too high for the insulation system.
● Observe the values in the following tables.
SIMOTICS machines can be operated with SINAMICS G converters and SINAMICS S
converters (uncontrolled and controlled infeed) when maintaining the permissible peak
voltages.
