Option 109
Below is an example (available when SBN=0001):
1. Confirm that the upper side phase order of MCB and MB1 are clockwise (customer’s
responsibility);
2. Disconnect the motor cable at the motor side;
3. Short-circuit both the input cable and output 3 phases cables of the VFD one by one;
4. Close MSS1 (in test position);
5. Check the underside phase order of MCB and MB1 with multimeter at measuring
points one by one. Make sure the phase order of this circuit is correct.
6. Check other main circuits phase order as the same procedure one by one (if
SBM>=0002)
Phase order check for PTs
1. Check the primary cable connection of PTs and make sure the phase order is correct.
2. Check the wirings connection between the secondary side of PTs and Rsyc-01 board.
Make sure the phase order is correct.
