DANGER
EXPLOSION HAZARD - MAY CAUSE DEATH
Ensure the area in which you perform this operation is non-hazardous. Performing this operation

If you have two power modules installed (8-slot chassis only), 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.)
