Applying DC Power to the Inverter
NOTICE
DC REVERSE POLARITY
Before making the final DC connection or closing the DC breaker or disconnect, check
cable polarity at both the battery and the inverter/charger. Positive (+) must be connected to
positive (+). Negative (–) must be connected to negative (–).
Failure to follow these instructions can result in equipment damage.
To 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 battery side of the disconnect or breaker.
Note: Voltage should be between 40 to 64 volts for a 48-volt system. If the DC voltage
is low, the battery bank must be charged externally. Charge the battery bank, and then
restart the functional test.
If the DC voltage is lower than the Low Battery Cut Out (LBCO) setting (44 volts for a
48-volt system) a DC Under Voltage Fault (F48) will be triggered. If the DC voltage is
lower than the default LBCO voltage, lower the LBCO setting accordingly.
2. Apply battery (DC) power to the inverter by closingthe battery bank DCdisconnect.
The inverter will power up in standby mode, and the inverter information panel will
display Stb(standby), as shown in Figure 36 .

Enabling the Inverter
Invert mode is enabled by default, and the Conext XW Pro 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 in Figure 37 . If the Conext XW Pro
powers up in standby mode, press the STARTUP/SHUTDOWN button momentarily to
change the mode from standby to operating.
