5.2.2 Electrical connection
DANGER
Risk of fatal injuries due to electric shock!
If the power supply is not switched off before working on the
product, the drive controller is not separated from the power
cables, or cables are connected incorrectly, fatal injury may be
caused from electric shock.
•
Switch off energy supply before carrying out all assembly,
adjustment and maintenance work and secure against re-
connection.
•
Only allow qualified electricians to work on electrical
automated systems.
•
Disconnect the drive controller from the power supply. The
intermediate circuit capacitors must be discharged. Wait for
approx. 15 minutes for the capacitors to discharge.
•
Observe order when connecting the cables (first ground cable,
then conductors).
NOTICE
Damage to the connection cable is possible!
If the following preconditions are not observed when installing
the connection cables, the connection cable may become
damaged
•
Install connection cables free from tensile and torsion loads. If
necessary, use cable guide chains.
•
Comply with the minimum bending radius (7.5 times the cable
diameter).
•
Install the connection cable so that the motor's range of
rotation and function are not impaired.
NOTICE
Material damage possible to lines!
If the following prerequisites are not observed for installation of
lines, the lines may be damaged.
•
When installing the lines, observe the specifications in the line
manufacturer data sheet.
•
During operation of the axes across the full stroke too, make
sure that the lines do not become crushed, sheared or torn off.
•
Install the power cable and measuring system lines in separate
cable tracks.
