Note
The variable torque rating is the capability of the inverter to increase the nominal
power output for use with pump and fan applications.
When variable torque is selected the inverter ceases to have an overload
capacity.
Humidity Range
95% Non-condensing
Altitude
If the inverter is to be installed at an altitude > 1000m, derating will be required.
(Refer to MM440 Reference Manual)
Shock
Do not drop the inverter or expose to sudden shock.
Vibration
Do not install the inverter in an area where it is likely to be exposed to constant
vibration.
Electromagnetic Radiation
Do not install the inverter near sources of electromagnetic radiation.
Atmospheric Pollution
Do not install the inverter in an environment, which contains atmospheric pollutants
such as dust, corrosive gases, etc.
Water
Take care to site the inverter away from potential water hazards, e.g. do not install
the inverter beneath pipes that are subject to condensation. Avoid installing the
inverter where excessive humidity and condensation may occur.
Installation and overheating
Warning
The inverters MUST not be mounted in an horizontal position.
Mount the inverter vertically to ensure optimum cooling, see Figure 2-1 on page 23.
It is also possible to mount the inverters side-by-side.
Ensure that the inverter’s air vents are not obstructed. Allow 100 mm clearance
above and below the inverter.
