Frequently, several loads in one system are
controlled by several analyzer outputs, whe-
reby the power for the loads derives from a
common source.
Special care is needed when wiring the loads
to minimize interference from switching these
loads:
• avoid connecting the loads in series:
2.7.4 Driving multiple loads
Fig. 2-20: Loads in series
• It is recommended to wire the loads in
parallel, and to separately connect each
load to the power supply: Beginning at
the distribution point, lay both the + and
the - wires for each load together to the
load (Fig. 2-21). Interference is further
reduced if a twisted multi-core cable is
used.
Distribution point
Lay cables to the loads
together as far as possible
(using twisted-pair cables
if possible)
