NOTE: Check to make sure the toroid transformer has the correct ‘PRI’ voltage values for the application. See Figure
7.5 for typical labeling of toroid transformer.

7.3 Optional Transformer Wiring (Cabling) Quick Reference Guide
The optional transformer uses a separate wiring harness to connect the controls supply (power in from L1, L2 and L3)
terminal block connector (J9) to the control module and optional transformer. See below for wiring configurations. All
other wiring is the same as the low or high voltage connections.
NOTE: See Figure 7.9 for wiring harness configurations per supply input voltage.
