Installation
5.1
Control cabinet installation
}
The unit should be installed in a control cabinet with a protection type of at least IP54.
}
Install the system vertically on to a horizontal mounting rail. The venting slots must face
upward and downward. Other mounting positions could damage the safety system.
}
Use the locking elements on the rear of the unit to attach it to a mounting rail.
}
In environments exposed to heavy vibration, the unit should be secured using a fixing ele-
ment (e.g. retaining bracket or end angle).
}
Open the locking slide before lifting the unit from the mounting rail.
}
To comply with EMC requirements, the mounting rail must have a low impedance con-
nection to the control cabinet housing.
NOTICE
Damage due to electrostatic discharge!
Electrostatic discharge can damage components. Ensure against discharge
before touching the product, e.g. by touching an earthed, conductive sur-
face or by wearing an earthed armband.
5.1.1
Mounting distances
With control cabinet installation it is essential to maintain a certain distance from the top
and bottom, as well as to other heat-producing devices (see diagram). The values stated
for the mounting distances are minimum specifications.
The ambient temperature in the control cabinet must not exceed the figure stated in the
technical details. Air conditioning may otherwise be required.
