§ Connect the cable to the weighing platform as follows:
– Expose approximately 5 cm (2 inches) of the isolated wires for installation.
– Remove the casing from approximately 1 cm (1/2 inch) of the wires and attach ferrules
to the wire ends.
– Fit the ferrite ring over wires 3 and 4.
– Attach the wires securely to the screw terminals.
Pin Assignments:
No. Signal name Meaning
1 BR_POS Bridge supply voltage (+)
2 SENSE_POS Sense (+)
Bridge supply voltage
3 OUT_POS Measuring voltage positive
4 OUT_NEG Measuring voltage negative
5 SENSE_NEG Sense (–)
Bridge supply voltage
6 BR_NEG Bridge supply voltage (–)
! Refer to the data sheet or operating instructions for the weighing platform for details
on the assignment of wire colors to signals. Isolate any lines that are not used.
Weighing platforms with 4-conductor technology:
! When connecting a load receptor that uses 4-conductor technology, connect wire 1
(BR_POS) to wire 2 (SENSE_POS) and wire 6 (BR_NEG) to wire 5 (SENSE_NEG).
Connecting the Combics to AC Power
§ Check the voltage rating and the plug design.
$ The indicator has a built-in power supply which can be operated with a supply voltage of
100 V to 240 V. The power connection must be made in accordance with the regulations
applicable in your country.
§ To power a device of protection class 1, make sure the electrical outlet (mains supply)
is properly installed with a protective grounding conductor (protective earth, PE).
Safety Precautions
If the electrical outlet does not have a protective grounding conductor, have a certified
electrician install equivalent protection. The protective conductor must not be disconnected
at any time.
Connecting Electronic Peripheral Devices
§ Make absolutely sure to unplug the indicator from AC power before you connect
or disconnect a peripheral device (printer, PC, etc.).
Warmup Time
To ensure accurate results, the indicator must warm up for 30 minutes before operation.
Only after this time will the indicator have reached the required operating temperature.
Using Equipment Verified as Legal Measuring Instruments in the EU*
$ Allow the equipment to warm up for at least 24 hours after initial connection to AC power.
