It is mandatory to connect the shielding wire to the MAG 8000 device earthing; otherwise IrDA
communication will not work satisfactorily.
115 to 230 V AC (mains) power supply
Mains power input
Factory mounted PUR cable with 2 x 1 mm
2
(brown wire, blue wire) cable length = 3 m
Brown wire - L (Line, +) and blue wire - N (Neutral, -)
Mains power output
Female battery connector with blue and yellow wires; blue wire is ground. Female battery con‐
nector has to be connected to male connector 3.6 V DC on PCB board
Battery backup input
Male battery connector with black and red wires; black wire is ground. Male battery connector
has to be connected to female connector on backup battery
Functional ground
Black wire with terminal must be connected to the device encapsulation with a screw
Mains power supply has to be connected to a switch near water meter according to IEC 61010-1 clause 5.4.3.d
12/24 V AC/DC (line) power supply
Line power input
Factory mounted PUR cable with 2 x 1 mm
2
(brown wire, blue wire) cable length = 3 m
Brown wire - L (line, hot, positive) and blue wire - N (neutral, cold, negative)
Line power output
Female battery connector with blue and yellow wires; blue wire is ground. Female battery con‐
nector has to be connected to male connector 3.6 V DC on PCB board
