4.5.5 – Basic Functional Test
The following procedure should be followed once the installation is complete and before it is put
into service.
Step 1: Confirm All Connections
After the AC and DC wiring has been installed and connected, check that all connections are
correct and secure.
Step 2: Apply DC Power to the Inverter
1. Before applying DC power to the inverter, measure the voltage and check polarity at all
connections (Measure at the PHI 3.8 Battery side of the disconnect or breaker.)
2. Apply PHI 3.8 Battery (DC) power to the inverter by closing the PHI 3.8 Battery bank DC
disconnect. The inverter will power up in standby mode, and the inverter information panel
will display Stb (standby), as shown below.

Step 3: Enable the Inverter
Invert mode is enabled by default, and the Conext XW Pro or XW+ should begin inverting upon
transitioning from standby mode. If invert mode is disabled, the inverter information panel will
display "- - -" once out of standby mode, as shown below. If the Conext XW Pro or XW+ powers
up in standby mode, press the STARTUP/ SHUTDOWN button momentarily to change the mode
from standby to operating.
