Distributed command devices of the 3SB3 series can be quickly connected to the AS-Interface using AS-Interface enclosures. Using suitable components you can make your own enclosures with integrated AS-Interface or flexibly modify existing enclosures.

The following connection options are available for the AS-Interface:

• AS-Interface enclosure with standard fittings (with 1 to 3 command points),
• Customer-specific AS-Interface enclosures (with 1 to 6 command points),
• AS-Interface front panel modules (for 4 command points),

For further information on the AS-Interface, refer to "AS-Interface".

Enclosures

Color of enclosure cover:

• Gray, RAL 7035, or
• Yellow, RAL 1004, for EMERGENCY-STOP mushroom pushbuttons.

Color of enclosure base:

• Black, RAL 9005

Installation of AS-Interface slaves

The following slave types are available for connecting the command devices:

• Slave in A/B technology with 4 inputs and 3 outputs
• Slave with 4 inputs and 4 outputs
• F slave with 2 safe inputs for EMERGENCY STOP

The following table shows the maximum number of equippable slaves:

1) For metal enclosures with 4 command points, only 1 x slave 4I/4O or 4I/3O is possible.

Connection

One set of links is required in each case to connect a slave to contact blocks, to lampholders and to the connection element.

The connection elements are mounted in the front-end cable glands of the enclosure and are used for connection of the AS-Interface or for bringing unused inputs or outputs out of the enclosure.

For connection to AS-Interface can be selected between:

• Terminal for the shaped AS-Interface cable. The cable is contacted by the insulation piercing method and routed past the enclosure on the outside (possible only with plastic enclosure).
• Cable gland for the shaped AS-Interface cable or round cable. The cable is routed into the enclosure (preferable for metal enclosure).
• Connection using M12 plug

If less than all inputs/outputs of the installed slaves in an enclosure are used for connecting the command devices, free inputs and outputs can be routed on request to the outside through an M12 socket on the top or bottom side of the enclosure.

To supply inputs with power, the S+ connection of the slave must be assigned to the socket, for outputs the OUT– connection must be assigned.

Addressing is performed using the AS-Interface connections or the integrated addressing socket. An external power supply is not required.
