Safety Information
CAUTION!
Never try to open the module! If a repair should be required, return the module
to our factory. If the specifications in the instruction manual are not sufficient
for assessing the safety of operation, please contact the manufacturer to make
sure that your intended application is possible and safe.
Be sure to observe during installation:
• Switch off power supply before replacing or inserting a module.
• Protect the signal inputs of the modules against electrostatic discharge.
• Before commissioning it must be proved that the device may be connected
with other equipment.
• Observe correct shielding: To avoid interferences, the cable shielding must
be completely covered by the ESD shielding cap.
