Mount Semiconductor Fuses
Mount Semiconductor Fuses Mount 120/240V Transformer AT+/BT Power
Mount optional semiconductor fuses near the VPAC. Mounting
must conform to code requirements. Wiring diagrams show
proper connections.
The AT+ or BT transformer powers the AT+ or BT control card.
Mount the transformer within 12 in. (30.5cm) of the VPAC it
connects to.
