Handling PCD2 I/O modules
Disconnect the power supply before a module is inserted or removed on the
PCD1.M2220-C15! This also applies if changes are made (e.g. insertion/removal
of jumpers) to the module.
2.4.1
Insert module
Sheet metal parts for shielding purposes are visible on the base of the housing.
These must be precisely aligned on the module slots.
Any I/O module can now be pushed in on each of these slots (Slot IO 0 + IO 1).
1. To do this, the module with the socket connector (usually with a blue colour) is
first pushed in carefully and without excessive force in the direction of the sys
-
tem bus plug up to the stop. Guides help here.
2.
When the opposite end of the module is flush with the latch of the housing
base, press the module downwards in the direction of the housing base until
a clicking sound is heard. This ensures that the IO plug-in module cannot fall
out due to vibrations.

Remove module
Use your thumb to press the latch a max. 1 mm away from the module (i.e. from
the I/O connection plug or terminal) towards the outside. Using the other hand,
lift up the module at the I/O connection plug slightly above the latch and pull the
module out of the slot.
Make sure that the metal claws of the shielding plate are not bent inwards with
a tool (never lever out with a screwdriver). This could result in a short circuit
and damage the module or controller.
