3.1 Overview of installation
Warning
Danger of electric shock, short circuiting or unexpected
drive motion
• Always switch off all power supply before carrying out
mounting, installation and maintenance work.
Caution
Earth loops or ground loops could result in EMC protective
measures becoming ineffective, with high compensating
currents permanently damaging the motor unit.
• Connect only one cable screening to functional earth FE
(preferably the screen for the power supply cable).
• Do not link the GND terminal to any housing, screen or
functional earth FE !
Caution
Faulty pre-assembled lines may destroy the electronics
and trigger unexpected movements of the motor.
• For cabling the electric components of the system, use
only the cables listed as accessories (see Tab. 3/2). Only
in this way is proper system functioning ensured.
