AS-B Server Device Installation
The AS-B servers are designed for installation on DIN rails in a cabinet.
Installation orientation restrictions
The AS-B server must be installed horizontally, with the device label text in the upright position reading left to right. Any other installation orientations may exceed the automation server's thermal specifications, which can damage the device.
Installation on a DIN rail
A DIN rail is a common and convenient technique for installing an automation server 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 automation server rail and adjacent rails or other panel-mounted devices.
The AS-B server 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.
Installing the device on a horizontal DIN rail provides sufficient cooling air flow through the device. Installing the device on a vertical DIN rail can reduce the life span of the device.
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.
Installation in a cabinet
Install the AS-B servers horizontally in the cabinet with ample space between the DIN rails and devices for sufficient cooling air flow through the devices.
Screw terminals
The terminal blocks are removable, which means that they can be wired before the AS-B server is supplied. Replacing an AS-B server is done in seconds because no terminal wiring is affected. The terminal blocks are delivered with the device.
Spare terminal blocks can be ordered from Schneider Electric using the part number SXWASBCON10001.
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. If the labels on the wires do not indicate the intended terminals, consult the control panel documentation to determine the intended terminals.
You can use the AS-B installer kit (part number SXWASBINS10001) to wire the terminal blocks before the AS-B server is supplied. The kit consists of an AS-B server enclosure without electronics inside.
