Caution
Damage to other field bus devices
If you are using the external logic power supply via the
field bus adapter FBA-... (see chapter Accessories) there
will be a voltage of DC 24 V at pin 9.
• Check whether there is any danger for other field bus
slaves.
• Note the pin assignment in accordance with the assem-
