Special conditions for safe operation
• The M12 connectors were tested in accordance with table 8 of EN 60079-0 / table 5 of EN
61241-0 for group II and for a low mechanical risk with an impact energy of 4 joules.
• Do not separate the connectors when energized.
• Secure the connector by tightening the nut sufficiently. Tightening torque approx. 1.2 Nm to
1.5 Nm. This tightening torque is ensured as follows:
-Hand-fasten the coupling nut (0.4 to 0.5 Nm).
-Then turn by 3 notches using a screwdriver across the flats 14.
• The connector conforms to the requirements for an M12 connector in EN 61076-2-101.
The counterpart must also conform to this standard.
