Installation and Wiring 7
The standard connection is designed for 4-wire (non remote sensing) use. To convert to 6-wire (remote sensing)
applications, cut the two PC traces on each end of TB1 as shown in Figure 2-7.
Figure 2-7. Load Cell Wiring From Indicator
Note: The load cell shield wire should be connected to
one of the load cell cable clamp screws located on the
load cell mating connector.
Shielding is connected at only one end
(typically at the indicator end). If
connected at the strain gauge end,
disregard Figure 2-8.

2.9 Standard Surge Protection Board
The UMC600 comes with a factory installed surge suppression board. The suppression board stops the flow of
excess voltage to the CPU board and attaches to TB1 on the CPU board just by pressing it into TB1 and tightening
the connector screws.
