4 Installation Guide

Only well trained and qualified professionals are allowed to carry out the
operations mentioned in this chapter. Please carry out operations according to
instructions presented in 1 "Safety Precautions". Ignoring these safety
precautions may lead to physical injury or death, or device damage.
Ensure the inverter power is disconnected before installation. If the inverter has
been powered on, disconnect the inverter, and wait for at least the time
designated on the inverter, and ensure the POWER indicator is off. Users are
recommended to use a multimeter to check and ensure the inverter DC bus
voltage is below 36V.
Installation must be designed and done according to applicable local laws
and regulations. IMO does not assume any liability whatsoever for any
installation which breaches local laws and regulations. If recommendations
given by IMO are not followed, the inverter may experience problems that the
warranty does not cover.
Indoors
-10–+50°C;

When the ambient temperature exceeds 40°C, derate 1% for every

additional 1°C;
It is not recommended to use the inverter when the ambient temperature is

above 50°C;
In order to improve reliability, do not use the inverter in cases where the

temperature changes rapidly;
When the inverter is used in a closed space eg control cabinet, use cooling

fan or air conditioner to prevent internal temperature from exceeding the
temperature required;
When the temperature is too low, if restart a inverter which has been idled

for a long time, it is required to install external heating device before use to
eliminate the freeze inside the inverter, failing to do so may cause damage
to
the inverter.
The relative humidity (RH) of the air is less than 90%;

The max RH cannot exceed 60% in the environment where there are

corrosive gases.
