Type designation key
Type designation describes the composition of the unit in short. The complete designation
code is divided in subcodes:
• The first digits form the basic code. It describes the basic construction of the unit. The
fields in the basic code are separated by hyphens.
• The plus codes (or option codes) follow the basic code. Each plus code starts with an
identifying letter (common for the whole product series), followed by descriptive digits.
The plus codes are separated by plus signs.
