Cautions and Warnings for Orientation and Mounting Procedures
HIGH VOLTAGE: Hazard of electrical shock. Disconnect incoming power before working on this control. Wait five (5) minutes before removing the front cover.
HIGH VOLTAGE:Hazard of electrical shock. Never touch the naked PCB (printed circuit board) portions while the unit is powered up. Even for switch portion, the inverter must be powered OFF before you change.
WARNING: In the cases below involving a
1.The unbalance factor of the power supply is 3% or higher.
2.The power supply capacity is at least 10 times greater than the inverter capacity (or the power supply capacity is 500kVA or more).
3.Abrupt power supply changes are expected, due to the conditions such as:
a.Several inverters are interconnected with a short bus.
b.A thyristor converter and an inverter are interconnected with a short bus.
c.An installed phase advance capacitor opens and closes.
CAUTION: Be sure to install the unit on
CAUTION: Be sure not to place any flammable materials near the inverter. Otherwise, there is the danger of fire.
CAUTION: Be sure not to let the foreign matter enter vent openings in the inverter housing, such as wire clippings, spatter from welding, metal shavings, dust, etc. Otherwise, there is the danger of fire.
CAUTION: Be sure to install the inverter in a place that can bear the weight according to the specifications in the text (Chapter 1, Specifications Tables). Otherwise, it may fall and cause injury to personnel.
CAUTION: Be sure to install the unit on a perpendicular wall that is not subject to vibration. Otherwise, it may fall and cause injury to personnel.
CAUTION: Be sure not to install or operate an inverter that is damaged or has missing parts. Otherwise, it may cause injury to personnel.
CAUTION: Be sure to install the inverter in a
CAUTION: Be sure to maintain the specified clearance area around the inverter and to provide adequate ventilation. Otherwise, the inverter may overheat and cause equipment damage or fire.
