TAC Xenta 400 I/O modules
4 Installation
When connecting G0 to ground, each TAC Xenta unit must have its
own connection to the ground rail, i.e. jumpers cannot be used for the
G0 terminals. Please refer to the figure on the next page.
Several units may share the same ground rail, but every unit with
measuring inputs and/or analog outputs must have all its ground
connections with the same ground rail.
In other words, a discontinuation in the ground rail must not split a
controller or separate it from the connected units.
