Where conduit is to be connected, lay the same up to the cable entry preferably using flexible conduit at the level switch end. While laying the conduit ensure that there is no chance of accumulated condensate flowing inside the level switch. Use condensate / Moisture trap if required. Now pass the cable/cables leaving desired numbers of cores through the conduit and the cable ends inside the switch head.

Alternatively, provide suitable cable gland at the Level switch cable entry and use annored cable (without conduit) and directly wire the same to the Level switch terminals. Remove any restriction provided to stop the movement of switches during transit.
