Pre-startup inspections
Item to Inspect Description Checked
Auxiliary equipment Look for auxiliary equipment, switches, disconnects, or input fuses/circuit breakers that may
reside on input power side of drive or output side to motor. Examine their operational readiness
and ensure they are ready in all respects for operation at full speed. Check function and
installation of pressure sensors and encoders, etc. used for feedback to drive. Remove power
factor correction caps on motor(s), if present.
Cable routing Ensure that input power, motor wiring and control wiring are in three separate metallic conduits
for high frequency noise isolation. Failure to isolate power, motor and control wiring could result
in less than optimum drive and associated equipment performance.
Control wiring Check for broken or damaged wires and connections. Check the voltage source of the signals, if
necessary. The use of shielded cable or twisted pair is recommended. Ensure the shield is
terminated correctly.
EMC considerations Check for proper installation with regard to electromagnetic capability.
Environmental conditions See equipment label for the maximum ambient operation temperature limits. Temperature is
not to exceed 104°F (40°C). Humidity levels must be less than 95% non-condensing.
Proper clearance Units require top and bottom clearance adequate to ensure proper air flow for cooling in
accordance with the unit size.
Fusing and circuit breakers Check that all fuses are inserted firmly and in operational condition and that all circuit breakers
are in the open position.
Grounding The equipment requires a dedicated ground wire from its chassis to the building ground. Check
for good ground connections that are tight and free of oxidation.
Input and output power
wiring
Check for loose connections. Check for proper fusing or circuit breakers.
Panel interior Equipment interior must be free of dirt, metal chips, moisture, and corrosion. Check for harmful
airborne contaminants such as sulfur-based compounds.
Switches Ensure that all switch and disconnect settings are in the proper position.
Vibration Look for any unusual amount of vibration the equipment may be subjected to. The panel should
be mounted solidly or use shock mounts as necessary.
Checked by:
Date:
Start-up procedure
Electrical Hazard:
EQUIPMENT HAZARD. The drive contains dangerous voltages when connected to line
voltage. Installation, start-up, and maintenance must be performed only by qualified
personnel. Failure to perform installation, start-up and maintenance by qualified
personnel only could result in death or serious injury.
1. Perform pre-start procedure.
2. Ensure that all operator devices are in the OFF position.
3. Keep the built-in disconnect switch in the OFF position. Apply voltage to the unit. DO
NOT operate drive now.
4. Confirm input line voltage is balanced within 3%. If it is not, correct input voltage
imbalance before proceeding. Repeat this procedure after voltage correction, when
applicable.
5. Confirm that the wiring matches the installation diagram that is supplied with the unit.
6. Ensure control wiring matches the installation application.
7. Turn the built-in disconnect to the ON position.
