40-pin Terminal Blocks: BMX FTB 40•0

At a Glance

There are two versions, available in two types of 40-pin terminal blocks:

Standard version

BMX FTB 4000 caged terminal block
BMX FTB 4020 spring terminal block

Hardened version

BMX FTB 4000H caged terminal block with gold plating
BMX FTB 4020H spring terminal block with gold plating

The hardened version of the terminal blocks are only dedicated to the hardened version of the modules.

NOTE: If you mix hardened and standard versions when fitting the terminal block to the module, there is a risk of terminal pin corrosion and a signal deviation.

WARNING

UNINTENDED EQUIPMENT OPERATION

Do not use the hardened version of the terminal block with a standard module.
Do not use the standard version of the terminal block with a hardened module.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

There are also preassembled cordsets with a BMX FTB 4020 terminal block at one end and flying leads at the other. The cordsets are available under reference BMX FTW ••5.

Cable Ends and Contacts

The 40-pin terminal blocks are designed for only one wire or one cable end.

Each terminal block can accommodate:

Bare wires:
- Solid conductor
- Stranded cable
Wires with ferrule (DZ5CE••••/DZ5CA•••• single type cable ends):

NOTE: When using stranded cable, Schneider Electric strongly recommends the use of wire ferrules which are fitted with an appropriate crimping tool.

Jumper bar

CAUTION

UNINTENDED EQUIPMENT OPERATION

Do not exceed the maximum capability of a single point of the terminal block when using it to carry the whole common current:

10 A maximum for a single point of the BMXFTB4000 terminal block
8 A maximum for a single point of the BMXFTB4020 terminal block

Failure to follow these instructions can result in injury or equipment damage.

Description of the 40-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:

	Caged Terminal Blocks BMX FTB 4000	Spring Terminal Blocks BMX FTB 4020
Illustration
1 solid conductor	AWG: 26...18 mm²: 0.13...1	AWG: 26...18 mm²: 0.13...1
1 stranded cable	AWG: 22...18 mm²: 0.34...1	AWG: 22...18 mm²: 0.34...1
1 stranded cable with ferrule	AWG: 22...18 mm²: 0.34...1	AWG: 22...18 mm²: 0.34...1
Minimum individual wire size in stranded cables when a ferrule is not used	AWG: 30 mm²: 0.0507	AWG: 30 mm²: 0.0507
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, use a flat-tipped screwdriver with a maximum diameter of 3 mm.
Screw tightening torque	0.4 N•m (0.30 lbf-ft)	Not applicable

Connection of 40-pin Terminal Blocks

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.

The connection cable is installed and held in place by cable clamps positioned below the terminal block.

NOTE: For installation where vibration can occur, do not let the cable loose from movement. Tighten cable to the bar of the shielding connection kit BMXXSP••00 or to rear mounting plate using cable clamp.

Labeling the Terminal Blocks

The labels for the terminal blocks are supplied with the module. They are to be inserted in the terminal block cover by the customer.

Each label has two sides:

One side that is visible from the outside when the cover is closed. This side features the commercial product references, an abbreviated description of the module, as well as a blank section for customer labeling.
One side that is visible from the inside when the cover is open. This side shows the terminal block connection diagram.
