4.2 Mechanical installation
•
Remove the keypad from the front of the controller if it is attached.
•
Attach the 2101 fieldbus module to the front of the controller. Use the fixing screw, which is
part of the delivery package, to secure the fieldbus module (see Fig. 4-1, pos. 3)
( ^ 1-1) .
Stop!
Tighten the fixing screw to ensure adequate PE connection of the 2102 fieldbus module.
4.3 Electrical installation
•
The communication of controllers 820X and 821X may be disturbed by electromagnetic
radiation. Use an additional PE cable to ensure safe communication (see Fig. 4-1 pos. 13).
This is not necessary with the controllers 822X and 93XX.
Caution!
The bus system continues operation even if the 2102 fieldbus system is disconnected from the
power supply because of an error.
If this is the case, the controller cannot be reached by the host.
Stop!
The polarity of the voltage supply must not be reversed, otherwise, the 2102 fieldbus module will
be destroyed !
•
Voltage supply:
– external 24 V (15 to 30 V) via plug-in connectors 39 (-) / 59 (+)
or
– internal via the controller (connection by plugging it on).
With 820X it is not possible to have an internal voltage supply via the controller.
