Transport and installation
b
CAUTION:
● Transport the product using the correct method that corresponds to the weight.
Failure to observe this could lead to injuries.
● Do not stack the inverter boxes higher than the number recommended.
● Ensure that installation position and material can withstand the weight of the
inverter. Install according to the information in the instruction manual.
● Do not install or operate the inverter if it is damaged or has parts missing. This can
result in breakdowns.
● When carrying the inverter, do not hold it by the front cover or setting dial; it may
fall off or fail.
● Do not stand or rest heavy objects on the product.
● Check the inverter mounting orientation is correct.
● Prevent other conductive bodies such as screws and metal fragments or other
flammable substance such as oil from entering the inverter.
● As the inverter is a precision instrument, do not drop or subject it to impact.
● Use the inverter under the following environmental conditions. Otherwise, the
inverter may be damaged.
