Transfer to the manual bypass for source S1:

1 - Manually transfer the load to source S1.

2 - Set switch Q2 4 to the OFF position (position 0).

3 - Set switch Q1BP 6 to the ON position (position 1).

The load is supplied by source S1 via the bypass.

4 - Set switches Q1 1 and Q3 7 to the OFF position (position 0).

The operation for source S2 is identical, using switches Q2 and Q2BP.

Interlocking of the bypass lines is ensured by use of a single key that must be inserted on the bypass switch to be operated.
