Mechanical Vibration; Contamination - HEIDENHAIN TNC 410 M Technical Manual

4.5.4 Mechanical Vibration

4.5.5 Contamination

January 2008
In order to avoid condensation, the electrical cabinet should be as air-tight as
possible. Within a closed system the climate control unit can release the
condensation, thereby reducing the relative humidity inside the electrical
cabinet. When the machine is switched off, e.g. with an emergency stop at
night, the climate control unit should continue to operate in order to prevent
condensation when the machine is switched on again.
Warning
The electrical cabinet should be as air-tight as possible.
If you have difficulties mounting the climate control unit, contact the
manufacturer.
Permissible vibration:± 0.075 mm, 10 to 41 Hz
Permissible shock:
Contamination level 2 in accordance with EN 61800-5-1 is permissible.
Warning
HEIDENHAIN cannot provide any warranty for inverter failures caused by
impermissible contamination. The deposition of dust from the ambient air,
precipitation of chemical contamination contained in the air or the natural
formation of dew after switching off the machine can form a conductive
layer on the inverter's live parts and may cause flashovers resulting in
corresponding damage.
HEIDENHAIN recommends providing the machine tool with suitable
equipment so as to prevent operation while the door of the electrical cabinet
is open. Corresponding information should be provided for the end user to be
made aware of the risk of working as well as increasing the contamination
when the door of the electrical cabinet is open.
