The 240 V cord is the one you left in a safe place, you know the spot, where it will be easy to find when you need it, that spot that slips your mind the moment you need to plug your Engel into the mains power.
The Type H Cord suits all those old Engels that are still ticking over with the rectangular plug and four round pins, thankfully Engel still make them.
Replacement 240V AC cord
