Safety Precautions
Power source
– The operator terminal is equipped with a 24 V DC input. Supply power other
than 24 V DC ± 15% will severely damage the operator terminal. Thus, check
the power supply supporting the DC power regularly.
Grounding
– Without grounding, the operator terminal may be severely affected by excess
noise. Make sure that the grounding is done properly from the power connec-
tor at the rear side of the operator terminal. When power is connected, make
sure that the wire is grounded.
– Use a cable of at least 2 mm
Ground resistance must be less than 100 Ω (class3). Note that the ground
cable must not be connected to the same ground point as the power circuit.
Installation
– Communication cables must be separated from power cables for operational
circuits. Only use shielded cables to avoid unpredictable problems.
During Use
– Emergency stop and other safety functions may not be controlled from the
operator terminal.
– Do not use too much force or sharp objects when touching the keys, display
etc.
Service and Maintenance
– Only qualified personnel should carry out repairs.
– The agreed warranty applies.
– Before carrying out any cleaning or maintenance operations, disconnect the
equipment from the electrical supply.
– Clean the display and surrounding front cover with a soft cloth and mild
detergent.
Dismantling and Scrapping
– The operator terminal or parts thereof shall be recycled according to local
regulations.
– The following components contain substances that might be hazardous to
health and the environment: lithium battery, electrolytic capacitor and
display.
