WARNING
Chapter 1 Safety Instructions Chapter 1 Safety Instructions
Be sure to install the inverter on metallic materials (i.e., metal).
Otherwise, there is the danger of fire.
Be sure not to let the foreign matter enter the inverter, such as wire
clippings, spatter from welding, metal (zinc or ferrous) meshavings and etc.
Otherwise, there is the danger of getting burned due to short circuit.
1.4 Cautions for Installing
HAZARD
Do not operate electrical equipment with wet hands.
Do not operate wiring unless the power supply is completely
off.
Do not open the front cover or perform wiring while the
inverter is powered ON. Otherwise, there is the danger of electric
shock.
Do wait at least 10 minutes after the power is disconnected
before performing the work of wiring or inspection. Otherwise,
there is the danger of electric shock.
WARNING
Do not install or operate if the inverter is damaged or has parts
missing to prevent injury to personnel or loss of property.
The main loop terminal should be tightly connected to the cable.
Otherwise, the inverter may be damaged due to loose contact.
The ground terminal must be reliably and properly grounded to
ensure security. To avoid common ground impedance, multi-
piece inverters should be grounded at one shared point, as shown
in the Figure 1-1.

DO NOT connect control terminals (except terminals marked"TA", "TB"
and "TC") to AC 220V power supply, which may cause damage to the inverter.
DO NOT connect AC power supply to the output terminals marked "U", "V"
and "W". Otherwise, it may cause damage to the inverter, as shown in the
