General installation guidelines
Please note during installation:
}
The unit should be installed in a control cabinet with a protection type of at least IP54.
}
Fit the control system to a horizontal mounting rail. The venting slots must face upward
and downward. If other mounting positions are used there will be insufficient ventilation.
}
Use the locking element on the rear of the unit to attach it to a mounting rail.
}
In environments exposed to heavy vibration, the unit should be secured against lateral
movement by using a fixing element (e.g. retaining bracket or end angle).
}
To comply with EMC requirements, the mounting rail must have a low impedance con-
nection to the control cabinet housing.
}
The coated versions of the PNOZmulti units are suitable for use where there are in-
creased environmental requirements on temperature and humidity. Please refer to the
technical details.
}
Note the relevant standards when wiring the control cabinet. For example:
–
DIN EN 61439-1 (VDE 0660-600-1):2012-06 Low-voltage switchgear and control-
gear assemblies – Part 1 General rules,
–
DIN EN 61439-2 (VDE 0660-600-2):2012-06 Low-voltage switchgear and control-
gear assemblies – Part 2: Power switchgear and controlgear assemblies,
–
DIN EN 60204-1, DIN EN 69439-1,
–
Machinery Directive 2006/42/EC,
–

Positioning of units
The position of the expansion modules is defined in the PNOZmulti Configurator. The ex-
pansion modules are connected to the left or right of the base unit, depending on the type.
}
Install the expansion module in the position in which it is configured in the PNOZmulti
Configurator.
For module selection please refer to the online help for the PNOZmulti Configurator
The position of the expansion modules is defined in the PNOZmulti Configurator. The ex-
pansion modules are connected to the left or right of the base unit, depending on the type.
Please refer to the document "PNOZmulti System Expansion" for details of the number of
modules that can be connected to the base unit and the module types.
