Chapter 4 Installation guide
4.1 What this chapter contains
This chapter introduces the mechanical and electrical installations of the inverter.
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 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. HITACHI does not assume any liability whatsoever for any
installation which breaches local laws and regulations. If recommendations
given by HITACHI are not followed, the inverter may experience problems
that the warranty does not cover.
4.2 Mechanical installation
4.2.1 Installation environment
Installation environment is essential for the inverter to operate at its best in the long run. The
installation environment of the inverter should meet the following requirements.
Environment
Condition
Installation
site
Indoors
Ambient
temperature
-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 an 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.
Humidity
The relative humidity (RH) of the air is less than 90%;
