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 upward
and downward. Other mounting positions could damage the safety system.

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 of the PNOZmulti units in the control cabinet must not exceed
the figure stated in the technical details. Air conditioning may otherwise be required.
