¾ Please check that the input DC voltage meets the VDC specification of the inverter, and verify the correct DC
polarity connections have been made to the inverter.
¾ Connect the DC input voltage cables before engaging the front panel DC breaker.
¾ Use the following recommended cable sizes when connecting power to the inverter.
Model Capacity DC Input AC Input AC Output
24-1000RM 1 KVA #6 AWG #12 AWG NEMA 5-15R
48-1000RM 1 KVA #10 AWG #16 AWG NEMA 5-15R

4-3 Installation Tool Kit
Contents of the tool kit include:
•
Poly zip bag containing twelve M4 screws and two 6-32 screws,
•
Two large mounting brackets (23” or 24” rack mount),
•
Two small mounting brackets (19” rack mount),
•
One protective cover for AC input,
•
One RS232 Cable.
4-4 Locking Hardwire Adapter
¾ The optional adapter is a reliable locking NEMA 5-15 plug on one end and terminal screws on the other end.
The plug-to-terminal conversion is used to secure bare wire load circuit wiring to the output sockets of the
inverter. The adapter includes strain relief for the wires being connected to the terminals.

5. OPERATION
5-1 Connecting to the Input Power
¾ Turn off the DC breaker before connecting the DC voltage to the input terminal. The DC terminal strip will
accommodate ring terminals with wire sizes recommended in Chapter 4-2.
¾
NOTE:
Sparks will occur if the breaker is “on” when connecting the input DC voltage. This is a normal condition
due to the charging current draw from the DC voltage charging the internal capacitor of the inverter.
¾ Once the DC power has been connected, engage the DC breaker to operate the inverter.
5-2 Connecting the Loads
¾ Calculate the total power consumption (VA) of the load being attached to the output. Make sure that the total
power consumption does not exceed the rated load of the inverter.
¾
The load consumption can be monitored on the front screen of the inverter using the data button.
¾ Should the total load exceed the capacity of the inverter, remove uncritical loads until the total load is within the
capacity of the inverter. Distribute removed loads to alternate sources or additional inverters
