CONTROL CONNECTION
Wiring Recommendations
Before planning the installation, follow these recommendations. The parallel
cable routing should be minimized and the distance between the control
wiring and the power wiring should be maximized. It is recommended to route
control cables with different voltages in separate cable racks, trays or ducts.
It is recommended to use shielded twisted cable for all the data, signal or
control cables that exit the variable speed drive, with the shield correctly
bonded to ground. To ensure an effective shield bonding, it is recommended
to include in the SD300 front metal panel of the control board, EMC shield
clamps that ensure a 360º effective shield bonding.
Shield bonding
Digital signal cables must be grounded at both ends of the cable (when there
is no potential difference between equipment). It is recommended to use
independent shielded cables for digital and analogue signals. When using
multiple analogue signals do not use common return for them. If a low-
interference is experienced (hum loops) using analogue signals disconnect
the shield grounding from one of the ends. Please refer to section
“Recommended Cable Section” for wire specifications and recommended
tightening.
