The 460 Analog Input Module
9 - 16
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 connector 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
lower end of the module. You can pull the module out of the
subrack with a grip with swivels outwards.
