Remove an analog input/output module as follows:
Step Action
1 Release the upper locking bar on the subrack and swivel it upwards and
out.
2 Slacken the screw in the upper part of the front connector. This causes the
front connector to be pressed out of the female connector of the module.
Contacts F+ and F- of the enable input at the upper end of the front con-
nector are thus opened first. If the enable input is active, power is removed
from the outputs and the module is isolated from the S5 bus.
3 Swing the front connector out and lift it away from the support pin of the
module.
4 Release the module by rotating the locking pin by 90 o at the lower end of
the module. You can pull the module out of the subrack with a grip with
swivels outwards.
