All connectors are crimp type. These can be easily disassembled,
if desired for easy of installation.
See table for pin configuration and colour code of the network
cable. DO NOT MIX THE PINS AND THE CABLE COLOURS!
Note ! Apply a thin layer of pure Vaseline on the connector threads and make
sure the connectors are properly secured to the receptacle by the
coupling ring. The connectors are weather proof according to IP56,
when properly installed. All unused Robnet plugs must be fitted with
the plastic cap to keep the connector free from dirt and moisture. A
separate screw cap for the Control unit comes as part of the installation
kit.
