Chapter 4 Installation and commissioning
4-1.
Use of the environment
(1)
Environmental temperature -10°C to 50°C. Above 40°C, the capacity will decrease 3%
by each 1°C. It is not advisable to use inverter above 50°C.
(2)
Prevent electromagnetic interference, and away from interference sources.
(3)
Prevent the ingress of droplets, vapor, dust, dirt, lint and metal fine powder.
(4)
Prevent the ingress of oil, salt and corrosive gases.
(5)
Avoid vibration.
(6)
Avoid high temperature and humidity or exposure to rain, humidity shall be less than
90% RH (non-condensing).
(7)
Altitude below 1000 meters, otherwise degrading 1% per 100m
(8)
Never use in the dangerous environment of flammable, combustible, explosive gas,
liquid or solid.

Figure 4-1: ST500 Series Each power level installation space requirement
ST500 Series frequency inverter heat radiator circulated from bottom to top, when more than
one inverter work together, usually mounted side by side. In the case of the need to install them by
upper and lower rows, due to the heat of the lower inverters rising to the upper equipment, fault
maybe caused, heat insulation deflector and other objects to be installed.
