7.1 Safety instructions
WARNING
•
Installation and initial commissioning of the device may only be carried out by
specially trained personnel who are provided with a detailed technical manual.
Such specialist staff include authorised, trained specialists employed by the manu-
facturer, the authorised dealers and the relevant service partners.
•
The control cabinet must be positioned in such a way that the emergency stop
main switch or the emergency stop pushbutton (optional) is located in the imme-
diate vicinity of the test bench at a height of 0.6...1.7 m above the stand level and
can be assigned to the correct test bench in the case of test halls with several sys-
tems. This is necessary in order to fulfil the emergency stop function according to
DIN EN ISO 13850. The "Control On" status light shall be fully visible from the test
site.
•
Electrical work must only be performed by a specialist electrician in compliance
with the national regulations, directives and standards. Accordingly, an electrical
test/measurement must also be carried out and recorded.
•
All parts of the electrical equipment must be protected from moisture and humidi-
ty.
•
Even when the main switch is switched off, parts of the optional control cabinet
heater (components, terminals, cores, cables, etc.) are still live. During service
work, the system must be depressurised and de-energised.
•
For all work (including assembly, repair and maintenance work) on the test bench
(e.g. control cabinet, roller set, other additional parts), it must be ensured that the
main switch is switched off and secured against being switched back on.
•
For all work in the roller set, it must be ensured that the main switch is switched
off and secured against being switched back on and, where applicable, that the
motor circuit breakers are switched off.
•
For work in the control cabinet or on the roller sets, be aware of the (optional)
heater or hot parts.
•
Due to the coordination used in accordance with IEC 60947, the switching ele-
ments (contactors) in the associated circuit must be replaced after a short-circuit/
housing short-circuit, and also if the B10d value of 1,300,000 switching cycles in
accordance with DIN EN ISO 13849-1/-2 is exceeded. Before connecting the supply
cable, it must be ensured that it is de-energised and, among other things, that the
5 safety rules are observed.
