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
(pumps 5.5 - 7.5 kW, Fig. 2) or the holder (included with the module) for screen
fastening (pumps up to 4 kW, Fig. 1) . 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.
