given in paragraph 7 of this Annex.
The connection of the external power supply is described in section 8.3.
6.3 Plug-in modules - changes in use
The device has not place for SLOT 3. The change occurs in modules installed in SLOT 1, SLOT 2
and SLOT 4.
New modules S1N-COM1, S1N-2AI and S1N-2AO are intended for SLOT1 and SLOT 2, which
are functionally identical to similar intrinsically safe modules but their signals are output to the
SLOT 1 terminal block, resp. SLOT 2 are not intrinsically safe and can be connected to common
devices whose electrical parameters are in accordance with the parameters of these modules.
Other types of power supply modules are intended for SLOT 4.
