EUCHNER MSC - 5.2. Calculation of the safety distance for an item of ESPE connected to the MSC system; 5.3. Electrical connections

English
Information in relation to connecting cables

Connection cross-section range: AWG 12–30, (single-conductor/multiple conductor)
(UL).

Only use copper wires (Cu) for 60/75 °C.

It is recommended to use separate power supplies for the safety module and for
other electrically powered devices (electric motors, inverters, frequency converters)
or other sources of interference.

Cables for connections with a length of more than 50 m must have a cross-section
of at least 1 mm² (AWG16).
The connections in the MSC system are listed in the table below:
