3-8 Safety Instructions for Electric Drives and Controls ECODRIVE03-SGP-03VRS
DOK-ECODR3-SGP-03VRS**-WA01-EN-P
DANGER
Dangerous movements! Danger to life, risk of
injury, severe bodily harm or material damage!
Ensure personal safety by means of qualified and tested
higher-level monitoring devices or measures
integrated in the installation. Unintended machine
motion is possible if monitoring devices are disabled,
bypassed or not activated.
Pay attention to unintended machine motion or other
malfunction in any mode of operation.
Keep free and clear of the machine’s range of motion and
moving parts. Possible measures to prevent people
from accidentally entering the machine’s range of
motion:
- use safety fences
- use safety guards
- use protective coverings
- install light curtains or light barriers
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 operator. 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 accessing 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 directly 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 installation for
possible malfunctions in all possible positions of
normal use before initial startup. If necessary, perform
a special electromagnetic compatibility (EMC) test on
the installation.
