4.2.4 Checking the Phase Sequence
Phase sequence check is to conrm whether the phase sequence of AC power
cables of the PCS is consistent with that of the transformer and power grid. If the
phase sequences are inconsistent, o-grid operation may be abnormal.
Step 1 Log in to the SmartLogger WebUI, choose Overview > Active Alarm, and check
whether the PCS reports a Reverse Phase Sequence on AC Side alarm.
Step 2 If the PCS reports a Reverse Phase Sequence on AC Side alarm:
1. Shut down the PCS, and turn o the power switches on the AC and DC sides
of the PCS.
2. Correct the wiring sequence of the PCS AC power cables. If the PCS AC power
cable is a multi-core cable, you are advised to exchange L1 and L3 shown in
the following gure to meet the stripping length requirement.
