Product Drawings
The front side of the DEV 1953 is identical for all product configurations. Just if the
product was ordered with Option 14, different power supply modules are installed.
The rear side of the DEV 1953 differs with respect to the installed module types and
quantities. Thus, only three drawings of the rear side are provided, other product
configurations can be easily derived.
