2. Safety instructions for electric drives and controllers
Festo.P.BE-CMMS-ST-G2-HW-EN 1008NH 19
Warning
Electronic devices are never fail-proof.
The user is responsible for ensuring that his system is brought into
a safe status if the electric device fails.
Warning
DANGER!
The stepping motor controller and, in particular, the braking
resistor can become very hot, and can cause serious burns if
touched.
2.4.3 Protection against touching electric components
This section concerns only devices and drive components with voltages over 60 V. It is
dangerous to touch components with voltages of more than 60 V, as this can cause an
electric shock. When electric devices are operated, certain components in these devices
are always under dangerous tension.
Warning
Dangerous voltage!
High voltage!
Danger of death or serious bodily injury due to electric shock!
For operation the relevant DIN, VDE, EN und IEC regulations, as well as all national and
local safety and accident prevention regulations must always be observed. The system
manufacturer or the user is responsible for ensuring that the following regulations are
observed:
Warning
• Before switching the device on, fit the covers and protective
screens so that the device cannot be touched.
For built-in devices, make sure that there is an external housing,
such as a control cabinet, to ensure that the electric components
cannot be touched.
Regulations BGVA3 must be observed.
Warning
Ensure that the minimum copper cross section is observed for the
entire length of the protective earth conductor in accordance with
standard EN 60617.
