Electrical Connection; Connection In A 4-Wire Configuration - HBM RTN Mounting Instructions

Electrical connection

5 Electrical connection
The following can be connected for measurement signal conditioning:
S Carrier-frequency amplifiers
S DC voltage amplifiers
that are designed for strain gage measurement systems.
If rubber-metal bearings are used, the construction is insulated against the
foundation. Here, please pay attention to DIN/VDE 0100, Part 410 as regards
the necessary potential equalization.

Electrical and magnetic fields often induce interference voltages in the
measuring circuit (also see section 5.5 "EMC protection").
Notice
Do not open the screwed cable gland on the load cell under any
circumstances; if it is opened inadvertently, the load cell must be sent to the
factory for repair.
