CAUTION:
Before connecting batteries, please install an
additiona
l fuse / DC circuit
breaker between inverter and batteries.
NOTE1:
Use only sealed lead acid, vented or Gel battery. Check maximum charging
voltage and current before using this inverter. For Lithium iron or NiCad battery, please
consult with installer for details.
NOTE2:
Please use 60VDC/125
–
250A fuse / circuit breaker.
NOTE3:
The overvoltage category of the battery input is II.
Please follow below steps to implement battery connection:
Step 1: Check the nominal voltage of batteries. The nominal inverter input voltage is
48VDC.
Step 2: Use two battery cables. Remove insulation sleeve 12
mm and insert conductor into cable ring terminal. Refer to
chart on right.
Step 3: Remove battery cover and follow battery polarity guide
printed near the battery terminal! Place the external battery cable ring terminal over the
battery terminal.
RED cable to positive terminal (+); BLACK cable to negative terminal (-).
