How to remove a power module
Turn the locking latch down until the arrow points down.
Unscrew the spring-activated knobs on both sides of the module.
Pull the module out of the enclosure as far as the lock mechanism will allow.
Release the lock by pushing the black plastic tab on each side of the module.
Pull the module up and out of the enclosure. 
How to install a power module
Reverse the procedure for installation of the replacement module. The display interface will indicate that 
the system has recognized a new module.
Caution: Secure the locking latch before tightening the spring-activated knobs on the module 
to ensure that the module makes proper contact in the unit. The power module will not operate 
unless the locking latch is locked.
Use two people to lift components weighing between 18–32 kg/40–70 lb.
