Attaching the Cable Entry
Please use extreme caution when performing any work on the equipment that
affects this cable gland. You must use a torque wrench.
The torque for this cable gland is 5 Nm.
Remove the protective cap from the bore hole on the indicator.
t
4 Insert the included cable gland through the bore hole and secure from the inside
t
using the locknut (1).
Insert the cable through the cable gland until the shielding (2) comes into
t
contact with the clamps (3). Tighten the screw-down nut (4) until the gasket (5)
inserted between the screw-down nut and cable forms a small beaded rim.
Check the shielding and clamps.
t
Securely connect the wires of the connecting cable in accordance with the
t
terminal assignments.
After you close the housing again, use a pressure gauge to check the integrity of
t
the IP69K protection. For details, contact the Sartorius Service Center.
Connecting Cables
Insert all cable wires through the ferrite case, wind them around the ferrite case
t
and then reinsert back through the ferrite case.
Screw the wires tightly into the clamps.

See the following pages for terminal pin allocation
Refer to the data sheet or operating instructions of the weighing platform for
t
details on the assignment of wire colors/signals. Ensure any lines that are not
assigned are insulated correctly.
When connecting a load receptor that uses 4-conductor technology (the cable of
t
the weighing platform to be connected only has 4 lines), connect clamp pairs 1
and 2 (EXC+ und SENSE+), and 5 and 6 (SENSE- und EXC-) with a wire jumper.
