7.1 Installation
To ensure immunity in industrial environments (EN 61000-6-2) the data cables
must be shielded cables and must be used with an EMC-compliant cable gland
(included with the module). For optimal transmission, the data cable pair should
be twisted and have surge impedance of 120 Ω.
Warning! Danger of electric shock!
The pump should be electrically isolated and secured against unauthorised
switch-on before beginning installation of the IF-Module.
Installation steps in accordance with Fig. 1:
• Remove the lid of the pump's terminal box
• Remove the cover (1)
• Install the module (2)
• Push the connection plug in all the way (3)
• Remove the existing Pg 9 and Pg 7 screwed connections (4a)
• Install the accompanying metal EMC cable glands (4b)
• Double pump: install DP module in the slave pump and insert the accompanying
cable here
• Strip and prepare the shield and the core wires (4c)
• Insert the cable(s) (4d)
• Screw the cable gland(s) into place (4e)
Electrical connection follows (see section below).

8.3 BACnet IF-Module
The BACnet instance number is set with the parameters C, E and F.
This requires conversion into a hexadecimal value1) (indicated in the following
by an ‘h’ suffix).
The instance number is divided between the three parameters (example 4660):
• Convert the instance number into a hexadecimal value (1234h)
• Expand the result to 6 digits by adding zeros on the left (001234h)
• C contains the two digits on the right (34h)
• E contains the two digits in the middle (12h)
• F contains the two digits on the left (00h)
Parameter C Parity* Data bits Stop bits
3N82
6S81
10 O 8 1
* N – no parity, E- even parity, O – odd parity
All other settings are reserved for expansions (see also the protocol description).
