The module does not provide a power supply for the encoder.
5.5.6 Mounting/Installation
When mounted outside the subrack, the ITxx module is inserted on a CPU
module PMx or on an ITxx module, already mounted on PMx (using a 96-pin
plug connector on the module).
All of the modules must be screwed to one another using the spacers
provided (3 spacers)!
The first ITxx, mounted directly on a CPU module, must be retained using
the
metal spacers
(these are included with the PMx). The electrical contact
which is established is required to identify the first expansion module.
The metal spacers are attached to the PMX using the M3 screws provided
together with the washers and spring washers.
