Applying DC Power to the Inverter
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.)
2. Apply battery (DC) power to the inverter by closing
the battery bank
DC disconnect.
The inverter will power up in standby mode, and the inverter information
panel will display
(standby), as shown in Figure 3-15.
DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Battery Circuit Breakers must be installed according to the specifications
and requirements defined by Schneider Electric.
• Servicing of batteries must only be performed by qualified personnel
knowledgeable of batteries and the required precautions. Keep
unqualified personnel away from batteries.
• Disconnect the charging source prior to connecting or disconnecting
battery terminals.
Failure to follow these instructions will result in death or serious injury.
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 damage to equipment.
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.
