Assembly and Operating Instructions – Parallel Arm Kinematics Kit

Removing covers without authorization, improper use, or incorrect installation and
operation may result in severe injuries to persons or damage to machinery.
Live components
Do not touch live components or power connections immediately after disconnecting
the device from the voltage supply because some capacitors may still be charged.
Discharge present energy storage units until the voltage has fallen below the protect-
ive extra-low voltage.
When the device is switched on, dangerous voltages are present at all power connec-
tions as well as at any connected cables and motor terminals. This also applies even
when the device is inhibited and the motor is at standstill. The fact that the operation
LED and other display elements are no longer illuminated does not indicate that the
device has been disconnected from the power supply and no longer carries any
voltage.
Automatic restart
Faulty mechanical blocking or internal safety functions of the device can cause a mo-
tor standstill. Removing the source of the malfunction or performing a restart can res-
ult in an automatic restart of the drive.
If an automatic restart is not permitted for safety reasons, proceed as follows:
1. Disconnect the device from the power supply and, if present, from the energy stor-
age unit.
2. Start troubleshooting.

Inspection and maintenance
Carry out maintenance and repair work only on a secured and de-energized machine/
system. Ensure a de-energized state of the machine/system before you start working
on it. Ensure a de-energized state for the entire time you work on the system.
Avoid unintentional start of the drives by switching off all required switches. Use a
padlock to prevent the main switch on the control cabinet from being switched on acci-
dentally.
