FIG. 3.9: AC CONFIGURATION ON THE AC CONTROL PCB
4. Locate the two small blue jumper wires in TB7 (bottom right). Position the jumpers as illustrated in
Fig. 3.9.
5. Connect to system to the AC service.
CAUTION: Once connected to the site electrical service, lethal voltages are present inside the unit.
The AC power is present at the circuit breaker, main contactor and isolation transformer. In addition,
the isolation transformer secondary outputs are “hot”. Review and understand the safety subtopic in
Section 5 before preceeding.
The system can be hard wired to electrical service, but ismore typically connected by a plug to an elec-
