Wiring the Inverter Input to a Power Supply

Step 6: In this step, you will connect wiring to

6 the input of the inverter. First, you must deter- mine whether the inverter model you have requires three-phase power only, or if it can accept either single-phase or three-phase power. All models have the same power connector terminals labeled L1, L2, and L3/N. So, you must refer to the specifications label (on the side of the inverter) for the acceptable power source types! For inverters which can accept single-phase power and are connected that way, terminal L2 will remain unconnected.

The wiring example to the right shows an L100 inverter wired for 3-phase input. Note the use of spade lug connectors for a secure connection.

NOTE: An inverter powered by a portable power generator may receive a distorted power waveform, overheating the generator. In general, the generator capacity should be five times that of the inverter (kVA) in a PWM (pulse-width modulated) control system, or six times greater in a PAM (pulse-amplitude modulated) control system.

CAUTION: Be sure that the input voltage matches the inverter specifications:

• Single/Three phase 200 to 240 V 50/60 Hz (up to 2.2kW)

Three phase 200 to 230V 50/60Hz (above 2.2kW)

Three phase 380 to 460 V 50/60Hz

CAUTION: Be sure not to input a single phase to a three-phase-only type inverter. Otherwise, there is the danger of fire.

CAUTION: Be sure not to connect an AC power supply to the output terminals. Other- wise, there is the danger of injury and/or fire.
