TECHNICAL INFORMATION
Assembly of Terminal Block

 

Assembly of Terminal Block

To make complete banks of terminal blocks, three accessories are necessary, they are : Mounting rails, End Plate and End Clamp. Connectwell terminal blocks are intended to be mounted on rails manufactured to International Standards. They are all designed for front mounting, so no rear access is necessary. The open side of last terminal block in row of the assembly must be closed by an end plate. End clamp / stop keeps the end plate in position and supports the unit, particularly, when arranged vertically. Partition / barrier / Separator plate are used for visual and electrical separation of different group of terminal blocks. Connectwell terminal blocks with Screw Clamp Connection & Spring Clamp Connection when mounted in this way, are totally protected  against accidental contact with live parts. However degree of protection changes when cross connecting accessories are installed. The terminal blocks are designed in such a way that all types of rated cross section can be connected without special preparation. All Connectwell terminal blocks can be easily cross connected by using suitable shorting links and studs / sleeves. Connectwell terminal blocks are  provided with suitable recesses for marking tags. Marking tags can be inserted prior to or after mounting of terminal blocks.

Connectwell terminal blocks have following advantages :

1 Additional terminal block can be installed at site
2 Terminal blocks can be installed in narrow cubicles and boxes
3 Individual terminal blocks can be replaced.
4 Terminal blockss are individually front mounted.
5 Terminal blocks of different types and sizes can be mounted together.


Instruction for Assembling Terminal Blocks

To determine length of the mounting channel required :

The thickness of one terminal + possible tolerance * x number of terminals + thickness of end plate + thickness of two end clamps + minimum 25 mm space on either side for mounting onto Control Panel.

Cross Connecting accessories can be added after completion of mounting of terminals. 

* Suggested tolerance is  0.2 mm  per terminal block pitch.
