NOTICE
・ Terminal connection for Whessoe Matic 550 (WM550) and Mark Space, refer to the next few pages.
・ Terminals 4 & 5 and 24 & 25 for HART devices are inter - connected on Explosion proof (Ex d) certified version.
・ Terminals 24 & 25 (and 24, 25 & 26 for spot temp.) will be intrinsically safe (i.s.) device connection
only when intrinsically safe certified version is selected.
