Service interface
• Install the device according to the manufacturer's instructions and any other valid standards and
regulations.
• Do not operate the device outside the specified electrical and thermal parameters.
• The relationship between the permitted ambient temperature for the electronics housing,
dependent on the range of application and the temperature classes is shown in the tables.
• Continuous duty temperature of the cable ≥ Ta +5 K.
• Do not disconnect electrical connections under voltage in an explosive atmosphere.
• Devices which are supplied by a plug (PROFIBUS PA):
Do not loosen or detach the plug as long as power is switched on.
• The maximum voltage U

external display (e. g. LUC-Z15) or a service adapter is connected to the device.
• The following components of the device correspond to the low risk of mechanical danger.
• They must be mounted in a protected position if installed within a hazardous location area rated
Zone 2 if mechanical danger is expected:
– Cover with inspection window
– Plug connectors of devices for supply/communication
F12 housing
• The input power circuit or the signal circuit in case of 4-wire versions of the device is isolated
from ground potential and has a dielectric strength of at least 500 V
T12 housing
• Do not open the connection compartments under voltage.
T12 OVP housing
• The input power circuit or the signal circuit in case of 4-wire versions of the device is isolated
from ground potential and has a dielectric strength of at least 410 V DC with respect to it.
