4.1 Important notes
Stop!
The drive controller contains electrostatically sensitive components.
The personnel must be free of electrostatic charge prior to assembly
and service operations.
Danger!
ƒ The connection of all pluggable terminals has to be effected in a
deenergised state.
ƒ Connecting and disconnecting the voltage supply (X2) due to the
charging processes of the DC bus capacitor may cause traces of
burning on the plug-in connection, and may result in a
destruction of the internal electronic circuit.
ƒ A false polarity of the DC supply can bring about the destruction
of the drive. Before switching the drive on, ensure that the
polarity of the D C supply is correct.
Note!
The following requirements have to be met with regard to the
trouble-free operation:
ƒ An installation according to EMC.
ƒ The shield of the motor cable has to be applied to PE potential on
a preferably large surface in order to prevent negative effects.
ƒ Theresolvercable,encodercable,andthemotorcablemayhave
a maximum length of 15 m!
ƒ The feeding power supply units have to be sufficiently
dimensioned. The power supply units have to be protected
against o vercurrent by means of appropriate input fuses.
