3.1 General Information
3.1.1 Safety precautions
Keep the following in mind during mounting and electrical installation:
National regulations for power installations
Interference and noise immunity
Operating conditions
Mounting position
Ensure that the main switch of the control or machine is switched off when
you engage or disengage connecting elements or connection clamps.
Ensure that the grounding conductor is connected. Interruptions in the
equipment grounding conductor may cause damage to persons or prop-
erty.
Incorrect or non-optimized input values can lead to faulty machine perfor-
mance and therefore to serious injury to persons and damage to equip-
ment. Modifications of the machine configuration should be done with cau-
tion and uncontrolled axis motions should be taken into account.
In order to be able to judge the behavior of an NC controlled machine, you
need to have fundamental knowledge about drives, inverters, controls and
encoders. Inappropriate use may cause considerable damage to persons or
property.
HEIDENHAIN does not accept any responsibility for direct or indirect dam-
age caused to persons or property through improper use or incorrect oper-
ation of the machine.
