Universal Robots is planning to make changes to the mechanical dimensions of the Control Box.
This applies to both e-Series and CB3.
New control boxes will be shipped during March 2019.
CB3 and e-Series control box will use same cabinet.
This causes slight changes on e-Series.
Significant changes are present on CB3, which include fan placement, feet, changed expansion openings and volume inside CB.
Contents of control box (connectors, PCB, etc.) will be unchanged. TP’s are unchanged.
The TP bracket has a new hole layout.
The inner dimensions for the new cabinet is the same, and thus the “cargo bay” remains at maximum 447x129x197[mm]. However, some of the cable interfaces are moved, space requirements must be checked per application in the STP file.
Handle has slightly different dimensions, and a decreased c-c hole pattern of 117mm.
The feet on the cabinet has a new design, that resembles that of the e-series. Refer to STP.

The four round holes for cable glands and Ethernet connection has new positions. Furthermore connectors for teach pendant and power, also has new positions to accommodate the new feet design.
Expansion holes have same 75x120[mm] dimensions, but a new hole layout. See below.

Cargo bay dimensions is identical, but slight changes like additional weld studs require that interference check is conducted.
Fan filter is moved approximately 2mm.
Robot and power connectors moved slightly.
Moved. See below.
The cover plate for expansion openings are identical for CB3 and e-Series.
The cover plate has a seal, to accommodate IP rating of the CB.
