However,observe the following points:• the installer must select the cable material according to the operation mode (installation location andlaying type) and the national regulations.• Due to the construction, the recommended feed line for all cross-sections is a fine wire.• Copper wires must be used.• Rigid wires are not recommended for the use of 16 mm2cables.• The wires are to be installed in the correct position in order to minimise lateral forces on the netconnection. The lateral forces must not exceed 250 N.• The seal is run through a hole in the screw (below the screw head of the adapter housing) and the openingprovided and attached to the housing of the device.The following table shows the maximum wire lengths upon use of a REFUsol 08K ... 23K depending on thecable cross section with a voltage drop below 1 %:Line cross section 6.0 mm² 10.0 mm216.0 mm2Max. line length 30 m 50 m 70 m4.11.1 Fitting of supplied power plugThe cable fitting of the standard connector housing supplied allows 5 x 6 mm² to 5 x 16 mm² cables to beconnected.
