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 5 m (16 ft) cable length as standard. Cable lengths 10 m (33 ft) and
20 m (66 ft) are optionally available.
Lengths can be selected by the user up to an overall length of 300 m (980 ft) and are available by the
meter (order option "8") or foot (order option "A").
Overvoltage protection
The device is equipped with integrated overvoltage protection.
