Cabling PW3/PW20/PW60 to M-Bus
• Use shielded, twisted pair cable 322 or 3251.
• Shielding is especially recommended when the M-Bus cable is installed in areas with expected or actual
electromagnetic noise. Avoiding such areas is to be preferred.
• Connect the shield to a noise-free earth ground – only once per M-Bus connection.
• Power the CIPer Model 50 controller and the PW M-Bus Adapter with separate transformers – see
WARNING below.
