5 Installation and Connection
5.1 Unpacking and Packing
All C232 units are packaged separately in their own cartons and shipped inside outer
packaging. Use special care when opening cartons and unpacking units, and do not use
force. In addition, make sure to remove from the inside carton the Supporting
Documents and the type identification label supplied with each individual unit.
The design revision level of each module included in the unit when shipped can be
determined from the list of components (assembly list). This list should be carefully
saved.
After unpacking each unit, inspect it visually to make sure it is in proper mechanical
condition.
If the C232 needs to be shipped, both inner and outer packaging must be used. If the
original packaging is no longer available, make sure that packaging conforms to
DIN ISO 2248 specifications for a drop height ≤ 0.8 m.
5.2 Checking the Nominal Data and the Design Type
The nominal data and design type of the C232 can be determined by consulting the type
identification label (see Figure 5-1) One type identification label is located under the
upper covering flap of the front panel and another is on the inside of the unit. Another
copy of the type identification label is affixed to the outside of the C232 packaging.

The C232 design version can be determined from the order number. A breakdown of
the order number is given in Chapter 14 of this manual and in the Supporting Documents
supplied with the unit.
