Installing an Electronics Module on a Terminal Base
You install an electronics module directly onto the relevant terminal base, where it will connect to the power supply and address bus.
The devices are designed mainly for installing on DIN rails in a cabinet.
Consider a simple example:
Each device consists of two parts:
Terminal base
Electronics module
A separate terminal base means the terminal base can be installed and wired before the electronics module with the application program and data is supplied.
The terminal base is usually installed on a DIN rail, but it can also be mounted directly on the wall. The electronics module is easily plugged in to the terminal base and firmly locked by pushing the handles in place.
Replacing an electronics module is done in seconds because no terminal wiring is affected.
DIN Rail Installation
Install the terminal bases on a horizontal DIN rail.
A DIN rail is a common and convenient technique for installing a SpaceLogic device along with other associated control and monitoring devices. The most efficient ventilation is achieved with the wall-mounted DIN rail oriented horizontally and with adequate space provided between the SpaceLogic device rail and adjacent rails or other panel-mounted devices.

The terminal bases are connected to each other by sliding the terminal bases together using the built-in connectors.
To ensure that the correct electronics module is used with the correct terminal base, you must always check that the warning label on the terminal base backplane indicates which module type is to be connected. Write the intended module type, if it is not already printed, on the label.
Install only the module type that is indicated on the label on the terminal base backplane. A mismatch can cause electric shock and damage the electronics module.

HAZARD OF ELECTRIC SHOCK OR EQUIPMENT DAMAGE Install only the module type that is indicated on the label on the terminal base backplane. Failure to follow these instructions can result in death, serious injury, or equipment damage. |
If the label does not indicate the intended module type, consult the control panel documentation to determine the intended module type.
To prevent the modules from sliding sideways on the DIN rail, fix an end clamp for DIN 35 (part number SXWDINEND10001) tightly against the rightmost device on the rail. The end clamp is easily removed if you bend the snap lock open with a screwdriver.
The chain of devices can be split on multiple DIN rails (rows) by using an extension cord called S-cable. Maximum five S-cables are allowed per system. The S-cable connects the last (rightmost) device on one DIN rail with the first (leftmost) device on the next DIN rail. The complete chain of devices must remain within one cabinet for EMC reasons.
The following figure shows an example of how you can use an S-cable to connect devices that are installed on separate DIN rails in a cabinet. For sufficient cooling air flow through the devices, the DIN rails and the devices are installed horizontally in the cabinet.
The S-cable is available with right angle connectors and in 1.5 m (5 ft) and 0.75 m (2 ft 5 in) lengths. You can serially connect up to two S-cables to extend the length.
The following image shows the minimum space required for plugging/unplugging the S-cable from the device but also provides information on the minimum bend radius required to reduce the stress of the cable. The S-cable with straight connectors is a discontinued product, which can no longer be ordered from Schneider Electric.
Device Order
The order in which the devices are installed in the chain (I/O bus) is important. The devices should be installed in the following order:
Position 1 (leftmost): Power supply (mandatory)
Position 2: AS-P server (mandatory)
Position 3 to 32: Central IO modules and extra power supplies as needed based on power budget. One power supply can supply power for loads up to 30 W. Pour plus d'informations, voir Power Budget .
There is a limit of one automation server per I/O bus.
The rules are summarized in the following illustration.

Pull out the two handles on the left and right sides of the module.
Plug in the module to the terminal base, ensuring that the PCB header pins align correctly with the backplane socket, and press firmly.
Push the handles in firmly to lock the module in place.
