Changing the power block on chassis power units

An installation fixture which facilitates replacement of the chassis power blocks is available as an option. It is
designed to simplify mounting and dismounting of the blocks.
It serves as an installation aid which is placed in front of and secured to the module. The telescopic rails allow the
withdrawable device to be adjusted according to the height at which the power blocks are installed. Once the
mechanical and electrical connections have been removed, the power block can be removed from the module,
whereby the power block is guided and supported by the guide rails on the withdrawable devices. The power block
can then be lifted off the rail.
