44、all be 1 000 mm, unless there is only a single arm. 4.1.1.3 Overall length of EAS When measured in accordance with 5.1.3, the length of the energy absorbing system without connecting devices shall be 1 500 mm 4.1.2 Connecting device If the connecting device is a connector according to EN 12275, it s

45、hall be a type K connector. If an EAS is not fitted with a connector of type K according to EN 12275, refer to the information supplied by the manufacturer of the EAS (see Clause 7). 4.1.3 Connection to the safety line There shall be at least two arms intended for attachment to the safety line, unle
