    Additional RFI suppression may be obtained by placing inductors in each motor lead near the amplifier. Consult a Glentek applications engineer for inductor recommen- dations. Glentek stocks a complete line of inductors for virtually every application. IMPORTANT: The signal wiring to hall-sensors and encoder, and the signal inputs to the amplifier are susceptible to noise pickup.
