General installation guidelines
}
The control system 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. Other mounting positions could destroy the control system.
}
Use the notches on the rear of the unit to attach it to a mounting rail. Connect the con-
trol system to the mounting rail in an upright position, so that the earthing springs on the
control system are pressed on to the mounting rail.
}
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.
}
To comply with EMC requirements, the mounting rail must have a low impedance con-
nection to the control cabinet housing.
CAUTION!
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.
