• The M-Bus is connected polarity independent to the terminal "M" and "M".
• Impulse devices with floating contacts (reed contacts) are connected to the terminals
marked "P-" and "P+" using any polarity. If cable shielding is available, it can be
wired single-sided to the terminal marked "S".
• Impulse devices with optocouplers or electrically isolated transistor outputs must be
connected to "P-" and "P+" with the correct polarity.
• Impulse devices with S
and "S
-" terminals with consideration of the correct polarity. An additional power
0
supply of 12VDC to 27VDC sourcing minimum 30mA current must be wired to the
terminals "U+" and "U-".
Note: You can use only one of the two pulse inputs of PadPuls M1C.
