Cabling instructions
:
Do not coil excess cable of different types (for example, motor power and feedback) together. An
efficient transformer is formed at HF.
Cable lengths should ideally be trimmed to fit the application.
If excess cable cannot be trimmed, it should be laid in an 'S' or figure eight pattern (refer to the figure
below).
