Start-Up and Test
Prior to releasing an electrical drive system for regular operation after installation, the system should be
given a start-up test by qualified personnel. This assures correct operation of the equipment for reasons
of reliable and safe performance. It is important to make arrangements for such a check and that time is
allowed for it.
When power is applied for the first time, the drive automatically starts up in the frequency monitor
function of standard monitor mode with the 'default' parameters set as shown in the "FACTORY
SETTING" column of the parameter tables starting on page 36. If these settings are not optimal for
the application, program the desired settings before initiating a run. The drive can be operated with no
motor connected. Operation with no motor connected or use with a small trial motor is recommended
for initial adjustment or for learning to adjust and operate the drive.
Maintenance
1) Use power lockout/tagout procedures on the disconnecting means in accordance
with applicable electrical codes (see 1996 NEC Article 430-101) before performing any
drive maintenance.
2) Periodically check the operating drive for cleanliness.
3) Do not use liquid cleaning agents.
4) Keep the heatsink free of dust and debris.
5)
Periodically check electrical connections for tightness (with power off,
locked out, and with charge LED extinguished (see page 24 for location)).

Confirmation of Wiring
Make the following final checks before applying power to the unit:
1) Confirm that source power is connected to terminals L1, L2, L3 (R, S, T).
Connection of incoming source power to any other terminals will damage the drive.
2) The 3-phase source power should be within the correct voltage and frequency tolerances.
3) The motor leads must be connected to terminals T1, T2, T3 (U, V, W).
4) Make sure there are no short circuits or inadvertent grounds and tighten any loose connector
terminal screws.
