Presumably these are identical transformers? If not, all bets are off.

If you number the 4 terminals (2 primary, 2 secondary) on both transformers
identically, as P1, P2 (for the primary) and S1, S2 (for the secondary), then:

- Wire P1 to P1 and P2 to P2; and

- Wire S1 to S1 and S2 to S2.

The important thing is that the phase of the outputs match; if you reverse
the primary connections on one transformer, they will no longer have their
outputs in phase with each other (bad news!).
