When laid together with other cables (e.g. in a cable duct), the length of the 2-core
cable between QRA and AGQ1 must not exceed 20 m.
A maximum cable length of 100 m is permitted if the 2-core cable is run at a distance of
at least 5 cm from other live cables.
The length of the 4-core cable between AGQ1 and LMV5 is limited to 20 m.
A maximum cable length of 100 m is permitted if the signal line (ionization / black) is not
run in the same cable but separately at a distance of at least 5 cm from other live
cables.
