Type designation label
The type designation label includes an IEC and NEMA rating, C-UL US, and CSA
markings, a type code and a serial number, which allow individual recognition of
each unit. The first digit of the serial number refers to the manufacturing plant. The
next four digits refer to the unit’s manufacturing year and week respectively. The
remaining digits complete the serial number so that there are no two units with the
same serial number.
The type designation label is located on the front cover and the serial number label
inside the unit. Example labels are shown below.
