Cable specification
Unshielded cable, wire cross-section 0.75 mm
2
• Resistant to UV and weather conditions as per ISO 4892-2
• Flame resistance according to IEC 60332-1-2
As per IEC/EN 60079-11 section 10.9, the cable is designed for a tensile strength of 30 N (6.74 lbf)
(over a period of 1 h).
The device is supplied with 10 m (33 ft) cable length as standard.
Overvoltage protection
The device is equipped with integrated overvoltage protection.
Performance characteristics
Reference operating
conditions
