Action

Release the upper locking bar on the subrack and swivel it upwards and out.

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.

Swing the front connector out and lift it away from the support pin of the module.

Release the module by rotating the locking pin by 90o at the lower end of the module. You can pull the module out of the subrack with a grip with swivels outwards.
