Finishing Connection Work; Connecting The Converter - Siemens SIMOTICS XP 1MB5 Operating Instructions Manual

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.

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
– 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
– The connecting cables are laid in an open arrangement, so that the cable insulation
2. Close the terminal box with the cover fixing screws, see Chapter Technical data (Page 157).

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 converters (uncontrolled and controlled
infeed) when maintaining the permissible voltage peaks.
The insulation system of SIMOTICS machines corresponds to the specifications laid down in
IEC 60034-18-41 according to voltage stress category C (IVIC C = high stress).
