Note:
•
UMI-B1 UL series inverters should be installed in a clean and ventilated environment
according to enclosure classification.
•
Cooling air must be clean, free from corrosive materials and electrically conductive
dust.
3.1.2 Installation direction
The inverter may be installed in a cabinet.
The inverter needs be installed in the vertical position. Check the installation site
according to the requirements below. Refer to chapter Dimension Drawings in the
appendix for frame details.
3.1.3 Installation manner
The inverter can be installed in two different ways, depending on the frame size:
Figure 3-1: Wall mounting (for all frame sizes)
Figure 3-2: Rail mounting (for all frame sizes, but need optional installation bracket)
RH≤90%
No condensation is allowed.
-40~+158° F (-40° C–+70° C), and the temperature changing rate is
less than 1.8° F (1° C)/minute.
The installation site of the inverter should:
keep away from the electromagnetic radiation source;
keep away from contaminative air, such as corrosive gas, oil mist
and flammable gas;
ensure foreign objects, such as metal power, dust, oil, water can
not enter into the inverter (do not install the inverter on the
flammable materials such as wood);
keep away from direct sunlight, oil mist, steam and vibration
environment.
Below 3281ft (1000m)
If the altitude is above 3281ft (1000m, derate 1% for every
additional 328ft (100m).
≤ 5.8m/s 2
(0.6g)
The inverter should be installed on an upright position to ensure
sufficient cooling effect.
