About us
At a Glance
BMX MSP 0200 PTO modules requires the BMX FTB 2800/2820 28-pin terminal block to be inserted into the front of the module. These fitting operations (assembly and disassembly) are described below.
Cable Ends and Contacts
Each terminal block can accommodate:
NOTE: When using stranded cable, Schneider Electric strongly recommends the use of wire ferrules which are fitted with an appropriate crimping tool.
Description of the 28-Pin Terminal Blocks
The following table describes the type of wires that fit each terminal block and the associated gauge range, wiring constraints, and tightening torque:

Wiring constraints
Caged terminal blocks have slots that accept:
  • Flat-tipped screwdrivers with a diameter of 3 mm.
Caged terminal blocks have captive screws. On the supplied blocks, these screws are not tightened.
The wires are connected by pressing the button located next to each pin.
To press the button, you have to use a flat-tipped screwdriver with a maximum diameter of 3 mm.
Screw tightening torque
0.4 N•m (0.30 lb-ft)
Not applicable
DANGER
HAZARD OF ELECTRIC SHOCK
Turn off all power to sensor and pre-actuator devices before connection or disconnection of the terminal block.
Failure to follow these instructions will result in death or serious injury.
Installing the 28-Pin Terminal Block
CAUTION
TERMINAL BLOCK IMPROPERLY FIXED TO THE MODULE
Follow the procedure instructions to fix the terminal block to the module.
Verify that the screws are tightened.
Failure to follow these instructions can result in injury or equipment damage.
The following table shows the procedure for assembling the 28-pin terminal block onto a BMX MSP 0200 PTO module:
Assembly procedure:
Step
Action
1
Once the module is in place on the rack, install the terminal block by inserting the terminal block encoder (the rear lower part of the terminal) into the module encoder (the front lower part of the module), as shown in previous illustration.
2
Fix the terminal block to the module by tightening the 2 mounting screws located on the lower and upper parts of the terminal block.
Tightening torque: 0.4 N•m (0.29 lb•ft).
28 Pin Terminal Block Arrangements
The terminal block is arranged as followed:
CAUTION
UNEXPECTED EQUIPMENT OPERATION
Follow the wiring, mounting and installation instructions.
Failure to follow these instructions can result in injury or equipment damage.
