Turn off the input and output circuit breakers on the rear panel of the module to be
removed.

Disconnect the flat cable (module communication cable) from the right side of the module.
If the LCD screen happens to be connected to the module to be removed, you must also
disconnect the screen's power/communication cable and remove the LCD screen itself to
avoid accidental damage to it.

Unscrew the two screws that secure the module – one on the left side, one on the right side
(see item 2 in Figure 26 on page 28).

Two persons are required to remove the module. Let one person stand on the left side of
the module, the other on the right side of the module. Slowly pull the module out of the
shelf. Be prepared for the fact that when the module is pulled out about 15 cm its
weight will no longer be supported by the shelf and will be fully in the hands of the two
workers. (Before you take the module out of the shelf, have a place where to lay it down
after it is removed.)

If the LCD had been attached to the module that was removed, it must be reattached to
one of the MegaV2 250's remaining modules.

Attach the LCD screen to the module now, then attach the LCD cable to the LCD
screen, and power-on the screen. See section 3 on page 40 for instructions on how
to install the LCD screen.

The MegaV2 250 controller must be informed that a module has been removed from the
system. On the LCD control panel, from the main menu navigate to
"Setup > System > Number of modules". Decrease the total number of modules by one.
Depending on your configuration you may also need to decrease the number of redundant
modules by one.
