Safety instructions
DANGER
Dangerous movements!
Danger to life, risk of serious injury or damage to equipment!
Ensure personal safety, either by means of monitoring devices or by superior measures directly
on the system.
The measures depend on the specific system conditions and are determined based on a risk and
error analysis. The safety regulations applicable to the system must be taken into consideration.
Unintended machine movements or other malfunctions may occur when the safety equipment is
switched off, bypassed, or not activated.
Avoid operating high-frequency, remote-controlled, or radio devices in the vicinity of the device
electronics and cables. If this cannot be avoided, check the device and the system for
malfunctions in all working positions. In some cases, a special EMC inspection of the entire
system may be necessary.
Use a torque support if higher torques are required for tightening.
The following requirements must be met if the hand-held nutrunner is used as a stationary
device:
–
Do not enter the area of travel of the machine and its parts. Possible measures to prevent
unauthorized entry of persons include e. g. protective barriers, protective enclosures,
protective cover or photocells.
–
Barriers and covers must be rigid enough to withstand the maximum possible momentum.
–
The emergency OFF switch must be easily accessible in the immediate vicinity. Check the
function of the emergency OFF system before commissioning. If the emergency OFF switch
malfunctions, do not operate the device.
–
Protection against unintended start-up by means of an emergency OFF circuit.
–
Safely bring the drives to a standstill before accessing or entering the danger zone.
–
Additionally secure vertical axes from falling or dropping after the motor is switched off by
mechanical locking of the vertical axis, external braking/catching/clamping devices and
sufficient weight compensation of the axis.
–
De-energize any electrical equipment using the main switch and protect it against being
switched on again during maintenance and repair work, cleaning and long disruptions in
operation.
