Installing a Series System
• Xantrex recommends that you have an electrician set up the two PROsines
because knowledge of the electrical code, split-phase systems, and load
balancing is required.
• See page 3–3 for a list of tools and materials required for installation.
• See “Step 1: Designing the Installation” on page 3–4 for information about
wire sizes, over-current protection, and disconnection means.
• Connect the system as shown in Figure 7-1 on page 7–3.
Detailed procedures for setting up an AC series system are given below.
Connecting AC Input Wiring
To connect each PROsine to the utility 120/240Vac split-phase supply:
1. Assign one PROsine to Line 1 and one to Line 2 and maintain the same
assignment throughout the AC input and AC output wiring steps.
2. Connect 2-conductor-plus-ground cable to a 30A breaker on Line 1 in the
source panel, and to the panel’s neutral bus and ground bus.
3. Run the 2-conductor-plus-ground cable to the Line 1 PROsine and connect:
• The Line 1 conductor to its AC Input Line conductor (black)
• The neutral to its AC Input neutral conductor
• The ground to its AC Input ground terminal
4. Repeat steps 2 and 3, connecting the 30A breaker on Line 2, neutral, and
ground from the source panel to the input wires and ground of the L2
PROsine.
WARNING
Xantrex Technology recommends that all wiring be completed by a certified technician or
electrician to ensure adherence to approved electrical wiring regulations.
WARNING: Fire, Shock, and Energy hazard
Make sure wiring is disconnected from all electrical sources before you handle. All wiring
must be done in accordance with local and national electrical wiring codes. Do not connect
the output terminals of the
PROsines to any incoming AC sources.
