General installation guidelines
}
The unit should be installed in a control cabinet with a protection type of at least IP54.
}
Fit the safety system to a horizontal mounting rail. The venting slots must face upwards
and downwards. Other mounting positions could destroy the safety system.

}
In environments exposed to heavy vibration, the unit should be secured using a fixing
element (e.g. retaining bracket or end angle).
}
Push the unit upwards or downwards before lifting it 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 of the PNOZmulti units in the control cabinet must not exceed
the figure stated in the technical details, otherwise air conditioning will be required.
