Separating a Module from Its Terminal Base

Caution:
Swing the address key away from the
I/O module before disengaging an I/O
module from its terminal base.
To 'park' a module – Squeeze module sides above the disengage catch (17)
and pull up slightly to disengage the I/O module from the terminal base. The I/O
module is retained in the terminal base ('parked'), but all wiring connections are
now floating.
To remove a module – Squeeze module sides above the release catch (18) and
pull up to remove the I/O module from the terminal base.
