3 Mounting Instructions and Installation3.1 Guidelines for Engineering / InstallationThe following guidelines provide instructions for the safe integration of the product into larger systems or installations.• Regulations for safety and accident prevention must be observed for each application.• Devices may only be used when they are fitted and the enclosure is closed.• Provision must be made to enable that the products can be isolated from power at any time (for fixed installationsvia an all pole mains isolator switch or fuse); protective conductors must be grounded.• Supply voltages must comply with the specifications in the manual and tolerances must be observed.Caution:• Malfunctions may occur if the specified tolerances are either not met or exceeded!• Provisions must be made to ensure that the installation / the system is not triggered into dangerous orundefined states by power failures or interruptions.• Emergency stopping devices must remain effective in all operational situations and states.• Connection leads (particularly data transfer leads) must be provided and installed in such a way that theinstallation / system cannot be affected by capacitance or inductive interference. Measures must betaken so that undefined states cannot develop, even when leads are interrupted.• The products must be installed in such a way that unintentional activation of functions is avoided.• Wherever malfunctions may cause damage to equipment or to staff, additional external safety fail-safeswitching must be provided (such as limit switches, mechanical latches etc.).E20Process display and control/ Device Manual/ Issue: 07.01
