If you have two power modules installed, you can remove either one of them (but not
both) while the RTU is operating:
Removing a Power Module
1.
Disconnect the terminal block from the power module you want to remove.
2.
Push a flathead screwdriver into the opening in the lower right of the power
module and rotate the handle of the screwdriver upwards to rotate the module
upwards. (Note: Do not rotate the handle downwards as that may pop the cover
off of the power module.)

3.
Now you can grasp the power module and pull it out.
Replacing a Power Module
1.
Press the power module at an angle into the chassis with the tab at the rear end of
the module going into the matching slot of the chassis.
2.
Press the module in as you rotate it down and it snaps into place.
