Safety Instructions for Electric Drives and Controls

• Fences and coverings must be strong enough to resist maximum
possible momentum, especially if there is a possibility of loose parts
flying off.
• Mount the emergency stop switch in the immediate reach of the op-
erator. Verify that the emergency stop works before startup. Don't
operate the machine if the emergency stop is not working.
• Isolate the drive power connection by means of an emergency stop
circuit or use a starting lockout to prevent unintentional start.
• Make sure that the drives are brought to a safe standstill before ac-
cessing or entering the danger zone. Safe standstill can be achieved
by switching off the power supply contactor or by safe mechanical
locking of moving parts.
• Secure vertical axes against falling or dropping after switching off the
motor power by, for example:
– mechanically securing the vertical axes
– adding an external braking/ arrester/ clamping mechanism
– ensuring sufficient equilibration of the vertical axes
The standard equipment motor brake or an external brake controlled di-
rectly by the drive controller are not sufficient to guarantee personal
safety!
• Disconnect electrical power to the equipment using a master switch
and secure the switch against reconnection for:
– maintenance and repair work
– cleaning of equipment
– long periods of discontinued equipment use
• Prevent the operation of high-frequency, remote control and radio
equipment near electronics circuits and supply leads. If the use of
such equipment cannot be avoided, verify the system and the instal-
lation for possible malfunctions in all possible positions of normal
use before initial startup. If necessary, perform a special electromag-
netic compatibility (EMC) test on the installation.
