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