CAUTIONBefore applying power to the unit, inspect the entireinstallation as detailed in Table 3.1. Check mark those itemswhen completed.Inspect for Description ☑Auxiliary equipment • Look for auxiliary equipment, switches, disconnects, or input fuses/circuit breakers that mayreside on the input power side of the adjustable frequency drive or output side to the motor.Ensure that they are ready for full speed operation.• Check function and installation of any sensors used for feedback to the adjustable frequencydrive.• Remove power factor correction caps on motor(s), if present.Cable routing • Ensure that input power, motor wiring, and control wiring are separated or in three separatemetallic conduits for high frequency noise isolation.Control wiring • Check for broken or damaged wires and loose connections.• Check that control wiring is isolated from power and motor wiring for noise immunity.• Check the voltage source of the signals, if necessary.• The use of shielded cable or twisted pair is recommended. Ensure that the shield is terminatedcorrectly.Cooling clearance • Measure to make sure that the top and bottom clearance is adequate to ensure proper airflowfor cooling.EMC considerations • Check for proper installation regarding electromagnetic compatibility.Environmental consider-ations• See equipment label for the maximum ambient operating temperature limits.• Humidity levels must be 5%–95% non-condensing.Fusing and circuitbreakers• Check for proper fusing or circuit breakers.• Check that all fuses are inserted firmly and in operational condition and that all circuit breakersare in the open position.Grounding • The unit requires a ground wire from its chassis to the building's ground.• Check for good ground connections that are tight and free of oxidation.• Grounding to conduit or mounting the back panel to a metal surface is not a suitable ground.Input and output powerwiring• Check for loose connections.• Check that motor and line power are in separate conduits or separated shielded cables.Panel interior • Inspect to ensure that the unit interior is free of dirt, metal chips, moisture, and corrosion.Switches • Ensure that all switch and disconnect settings are in the proper positions.Vibration • Check that the unit is mounted solidly or that shock mounts are used, as necessary.• Check for an unusual amount of vibration.Table 3.1 Start-up Check ListStart Up and Functional Tes...
