The Allen Bradley 1756-TBE is an Extended-Depth Housing used when additional wire routing space in an RTB is required for applications. It is ordered separately and is a component of the Bulletin 1756 Removable Terminal Block Series that uses heavy gauge wiring. The I/O terminal block and extended-depth housing combination allows up to 628 sq. mm wire capacity.
The 1756-TBE Extended-Depth Terminal Housing protects wiring connections by providing a cover to the wired RTB when it is seated on the module. This housing is recommended when working with wire measurements greater than 36-18AWG or 23-14AWG on the sequence of events module. It has a 157.43 mm (6.198 inches) depth from the module front to the back of the chassis. The 1756-TBE replaces the standard housing on the front of the wiring arm that is not deep enough to accommodate 2.5 mm² (14 AWG) wiring.
When installing the 1756-TBE onto the module, align the bottom grooves side-by-side with the edges of the Removable Terminal Block. Slide the RTB into place until it snaps or locks with the housing. It is recommended that the field-side power is removed. Not taking this precaution can cause loss of process control, unintended machine motion, or personal injury.
