Please do never connect a supply voltage to the analog outputs as this will destroy the
output!
The CTratio is not a 2-wire sensor!
Power supply
Please use a power supply unit with an output voltage of
8
–30 VDC
with a power of
5 W
. The ripple should
be max.
200 mV
. Please use shielded cables only for all power and data lines.
The sensor shield has to be grounded.
Cable Assembling
The cable gland M12x1,5 allows the use of cables with a diameter of 3 to 5 mm.
Remove the isolation from the cable (40 mm power supply, 50 mm signal outputs, 60 mm functional inputs).
Cut the shield down to approximately 5 mm and spread the strands out. Extract about 4 mm of the wire
isolation and tin the wire ends.
Place the pressing screw, the rubber washer and the metal washers of the cable gland one after the other
onto the prepared cable end. Spread the strands and fix the shield between two of the metal washers. Insert
the cable into the cable gland until the limit stop. Screw the cap tight.
Every single wire may be connected to the according screw clamps according to their colors.
