Identify Date Code
The date code will be an ink stamp, normally located on the inside surface of the enclosures rear wall, towards the top endwall. It will be a 5 or 6 digit code. First two digits indicate the year it was built, the 2nd two digits indicate the week of the year, the 5th digit indicates the day of the week and the 6th digit (if used) indicates the shift. e.g. 083243 would indicate that enclosure was built by 3rd shift on Thursday, August 7, 2008.
