5.15 Potential at control voltage connections
The connections for the control voltage (< 30 V) relate to the common GND potential (exception: relay
contacts are potential-free). There is a potential isolation between the connections for the control
voltage and the PE conductor. It must be ensured that the maximum external voltage at the con-
nections for the control voltage cannot exceed 30 V (between the “GND” and “PE” conductor
terminals). A connection to the PE conductor potential can be made if required; fit a bridge between
the “GND” terminal and the “PE” connection (terminal for shield).
5.16 Option add-on modules
An additional module can be retrofitted in the slot provided if required (mounting
operating instructions of the additional modules).
The range of additional modules is constantly being extended and adapted to market requirements.
The currently available additional modules can be requested from ZIEHL-ABEGG.

Communication module
To integrate the device into a MODBUS network. The members can be
addressed automatically by an additional connection.
The device can be communicated with using the hand-held terminal type A-
G-247NW. Connection by cable via the MODBUS interface or wirelessly by
radio (AM-MODBUS- W).
On the AM-MODBUS-WB this can be done wirelessly using Bluetooth and
the “ZAset mobile” app.
