Power & Control Wiring
4.6. 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
2
/ 30 – 12 AWG.
4.7. Using the REV/0/FWD Selector Switch (Switched Version Only)
By adjusting the parameter settings the TECDrive 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.
