General installation guidelines
}
The control system should be installed in a control cabinet with a protection type of at
least IP54. Fit the control system to a horizontal mounting rail. The venting slots must
face upward and downward. Other mounting positions could destroy the control system.
}
Use the locking elements on the rear of the unit to attach it to a mounting rail. Connect
the control system to the mounting rail in an upright position, so that the earthing springs
on the control system are pressed on to the mounting rail.
}
The ambient temperature of the devices in the control cabinet must not exceed the figure
stated in the technical details. Air conditioning may otherwise be required.
}
To comply with EMC requirements, the mounting rail must have a low impedance con-
nection to the control cabinet housing.
