The Modbus interface is usually supplied fully assembled with the control
unit. If it is retrofitted, please observe the following points:
The Modbus interface is inserted into the (serial card / BMS card) slot
on the KLM-M control unit (part no. 2744747) or KLM-L control unit
(part no. 2744746). To do this, proceed as follows:
1. Isolate the KLM-M or KLM-L air handling and ventilation module from the
power supply.
2. Remove the cover of the (serial card / BMS card) slot using a screwdriver.
3. Remove the inner part of the cover with wire cutters.
4. Insert the Modbus interface into the free slot such that a plug-in
connection is made between the connection block of the Modbus
interface and the pins of the air handling and ventilation module
(connection block clicks into place).
5. Refit the slot cover.
6. Reconnect the power supply.
