4 Start Up and Functional Test
4.1 Pre-start
CAUTION
Before applying power to the unit, inspect the entire
installation as detailed in Table 4.1. Check mark those items
when completed.
Inspect for Description
☑
Auxiliary equipment
•
Look for auxiliary equipment, switches, disconnects, or input fuses/circuit breakers that may
reside on the input power side of the frequency converter 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 frequency converter.
•
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 separate
metallic 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 terminated
correctly.
Cooling clearance
•
Measure that top and bottom clearance is adequate to ensure proper air flow for 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 circuit
breakers
•
Check for proper fusing or circuit breakers.
•
Check that all fuses are inserted firmly and in operational condition and that all circuit breakers
are in the open position.
Earthing (Grounding)
•
The unit requires an earth wire(ground wire) from its chassis to the building earth (ground).
•
Check for good earth connections(ground connections) that are tight and free of oxidation.
•
Earthing (grounding) to conduit or mounting the back panel to a metal surface is not a
suitable earth (ground).
Input and output power
wiring
•
Check for loose connections.
•
Check that motor and mains are in separate conduit or separated screened cables.
Panel interior
•
Inspect 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.
