Wiring:
1. Connect AC power 115VAC, 50/60Hz to black and white primary leads (Fig. 2, pg. 1).
2. Measure output voltage across the secondary leads before connecting devices (Fig. 2, pg. 1). This helps avoiding potential damage.
- Yellow and Brown for 16VAC (open circuit voltage @ 115VAC approx. 16.6VAC).
- Black and Brown for 18VAC (open circuit voltage @ 115VAC approx. 18.8VAC).
3. Connect 16VAC device(s) to Yellow and Brown leads or 18VAC device(s) to Black and Brown leads
