Initial Commissioning; Confirmation Of Wiring; Start-Up And Test - Toshiba T300MVi MEDIUM VOLTAGE Instruction Manual

INITIAL COMMISSIONING

The drive should be commissioned by qualified personnel only. Below are some general steps
required for commissioning.

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. Other control voltages
may be required. Consult your custom equipment diagrams shipped with the drive for any
other requirements.
2) Verify that the power modules are properly installed and that there was no damage during
shipping or handling.
3) Verify that there are no loose connections or wires and that all of the required shipping split
connections have been made.
4) Verify all external control circuit wiring is complete and properly connected.
5) The 3-phase source power should be within the correct voltage and frequency tolerances.
6) The motor leads must be connected to terminals T1, T2, T3 (U, V, W).
7) Make sure there are no short circuits or inadvertent grounds and tighten any loose connector
terminal screws.

Start-Up and Test

Prior to releasing the drive system for regular operation after installation, the system must
be adjusted and tested 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.
