Concept
AS-B Device Installation
The AS-B devices are designed for installing on DIN rails in a cabinet.
A DIN rail is a common and convenient technique for installing an AS-B 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 AS-B rail and adjacent rails or other panel-mounted devices.
The AS-B must be installed on a horizontal DIN rail (going from left to right), with the device label text in the upright position reading left to right.

Install the device on a horizontal DIN rail. This position provides sufficient cooling air flow through the device. Installation on a vertical DIN rail can reduce the life span of the device.

Install the AS-B devices horizontally in the cabinet with ample space between the DIN rails and devices for sufficient cooling air flow through the devices.

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 terminal blocks are removable, which means that they can be wired before the AS-B device is supplied. Replacing an AS-B device is done in seconds because no terminal wiring is affected. The terminal blocks are delivered with the device. Use only terminal blocks delivered with the device or ordered from Schneider Electric. Spare terminal blocks can be ordered from Schneider Electric using the part number SXWASBCON10001.
You can use the AS-B installer kit (part number SXWASBINS10001) to wire the terminal blocks before the AS-B is supplied. The kit consists of an AS-B enclosure without electronics inside.
Install only a wired terminal block that matches the labeling of the terminals on the device. A mismatch can cause electric shock and damage the electronics in the device.

HAZARD OF ELECTRIC SHOCK OR DEVICE ELECTRONICS DAMAGE Install only a wired terminal block that matches the labeling of the terminals on the device. Failure to follow these instructions can result in death, serious injury, or equipment damage. |
If the labels on the wires do not indicate the intended terminals, consult the control panel documentation to determine the intended terminals.
