Prepare the following tools for the device expansion:
•
Phillips screwdriver size PZ1 and PZ2

During assembly, use the prescribed torques (see chapter
Comply with the following basic rules when extending devices:
Always fit the base module on the left in the 1st device row.
²
Always fit the expansion modules from left to right.
²
Always fit the expansion module with the key switches as the 1st module next to the base module.
²
Always fit the expansion modules without LEDs last.
²
Always install a power supply module PS203 on the left as the first unit in the 2nd device row.
²
Note that the PS203 must always have the same rated voltage as the base module.
²
In the 2nd device row, mount only input and output modules without light-emitting diodes
²
Always mount the redundant PS204 power supply module at the position furthest to the right in the
²
corresponding row when you're looking at it from the front. If a CB202 printed circuit board assembly is
present in the row, the CB202 printed circuit board assembly must always be mounted to the right of the
PS204 printed circuit board assembly (at the outermost position). You will find an example of this in
Chapter 3.1.4.2 Positioning
Note that the PS204 printed circuit board assembly must always have the same rated voltage as the base
