Prepare. Solder. Secure.
Disconnect power. Put the gland and housing parts over the cable first. Follow the equipment pin assignment. Solder the conductors to the cups, insulate each joint and check for shorts. Seat the connector seals and retain the cable jacket with the gland. Align the key before threading the coupling. Test continuity and isolation before service.
