recommenDaTIonS
1. Use shielded cable on all external connections. Ground one end of each shield, including speed sensor shield, to a single point on the EEG case.
2. Ground controller case to battery (-)
3. For magnetic pickups and CAN bus, use twisted wires at 14 turns per foot in wire length.
Wire the EEG7500 for either speed control or position control , detailed in this sections following figures. Items highlighted in the following
table are the minimum connections required before starting. Read this entire manual before starting. Determine what hardware devices
will be involved in the installation and ensure you know where they are being mapped to on this speed controller. Document your wiring
setup to make setup easier with the GAConfig Tool.
