General installation guidelines
}
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.
}
The ambient temperature in the control cabinet must not exceed the figure stated in the
technical details. otherwise air conditioning may be required.
}
The unit may be exposed to various types of acceleration during operation. Please note
the values stated in the technical details for vibration and shock stress. The acceleration
values do not apply when mechanical resonances occur. so the whole system should be
subjected to extensive testing.
}
For the unit to work properly, it must not be constantly exposed to heavy vibration.
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.
