Control Terminal Wiring
• All analog signal cables should be suitably shielded. Twisted pair cables are recommended.
• Power and Control Signal cables should be routed separately where possible, and must not be routed parallel to each other.
• Signal levels of different voltages e.g. 24 Volt DC and 110 Volt AC, should not be routed in the same cable.
• Maximum control terminal tightening torque is 0.5Nm.
• Control Cable entry conductor size: 0.05 – 2.5mm

/ 30 – 12 AWG.
4.7. Using the REV/0/FWD Selector Switch (Switched Version Only)
By adjusting the parameter settings the BFI-E3 can be configured for multiple applications and not just for Forward or Reverse.
This could typically be for Hand/Off/Auto applications (also known and Local/Remote) for HVAC and pumping industries.
