Always fit the on-site operation panel of the base module on the left.
•
Always fit the on-site operation panels of the expansion modules from left to right.
•
Always install a power-supply module PS203 on the right as the first unit in the 2nd device row.
•
Note that the PS203 must always have the same rated voltage as the base module.
•
Always mount the redundant PS204 power-supply module at the position at the very left in the corre-
sponding row (seen from the front). If a CB202 PCB assembly is used in the row, this CB202 PCB assembly
must always be plugged on the left of the power-supply module PS204 (at the very left).
•
Note that the power-supply module PS204 must always have the same rated voltage as the base module.
•
The distance between the device and the on-site operation panel is limited to not more than 5 m
(196.85 in) by the length of the connecting cable.
