● Due to the considerable weight of the device, ensure that a stable mounting footprint is
available for the Active Interface Module Chassis-2 and that there are no obstacles in the
rolling area (such as screws).
● Only roll the device horizontally into the control cabinet.
Never roll the device up or down an inclined ramp, as the high weight and center of
gravity of the device pose a serious risk of injury.
● You must remove the fan unit to screw the device to the rear mounting panel.
Attaching the mounting bracket
Secure the mounting bracket of the Active Interface Module Chassis-2 on the mounting
surface of the control cabinet.
When positioning the long holes (12 mm x 17 mm), ensure that no additional pressure is
applied to the rollers of the Active Interface Modules Chassis-2 during installation.
Tighten the M10 screws to a torque of 50 Nm.
