Electrical shock hazard!
DANGER
Electrical shock hazard! When an installed torque motor rotates, potentially dangerous
voltages are induced at the cable ends of the motor.
Insulate terminals and leads in open cable ends or take measures to prevent torque motors
Insulate terminals and leads in open cable ends or take measures to prevent torque motors
that have been installed from rotating.
There is also a risk of compression.
There is also a risk of compression.
DANGER
Danger due to high leakage currents
If high leakage currents are present, more stringent requirements may apply to the PE
If high leakage currents are present, more stringent requirements may apply to the PE
conductor. Warning signs may also be required on the PDS. You can find more detailed
information in the standard EN 61800-5-1.
Protective measures against residual voltages
DANGER
There is a shock hazard danger due to the residual voltages at the motor terminals!
When the power supply voltage is switched-out, active parts of the motor can have a
When the power supply voltage is switched-out, active parts of the motor can have a
charge of more than 60 μC. In addition, at open-circuit cable ends - e.g. when a connector
is withdrawn - even after the power has been disconnected, a voltage or more than 60 V
can be present for 1 s. This is the reason that you must apply the appropriate measures to
provide protection against residual voltages!

Attaching warning signs
All danger areas must be identified by well visible warning and prohibiting signs (pictograms)
in the immediate vicinity of the danger. The associated texts must be available in the
language of the country in which the product is used.
