For higher VA requirements, 110 or 220 Vac requirements, separate transformers used to power the load, or DC power requirements, use an interposing 220 V 4-relay module (TEC Relay Module P/N 540-147). NOTE: Refer to the unit wiring diagrams or consult with the local representative if terminations are missing or are different.
