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 expanding 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 LEDs.
²
Always mount the redundant power-supply module PS204 at the very right in the corresponding row
²
(seen from the front). If a CB202 PCB assembly is used in the row, this CB202 PCB assembly must always
be plugged on the right of the power-supply module PS204 (at the very right). You can find an example
for this in chapter
Note that the power-supply module PS204 must always have the same rated voltage as the base module.
