Products installation
4.1 Installation condition requirements
To ensure normal operation of the machine, the installation environment is required
as follows:
> The ingress protection of inverter is IP20. Moreover, as this product is an electronic
equipment, it shall not be placed in humid environment;
> Install indoors and avoid sunlight and rain;
> Ventilation of the room shall be good;
> The installation environment shall be clean;
> As some noise will be produced in operation, this equipment shall be installed far
from residential quarters;
> The installation ground shall be even enough, and firm enough to support the
weight of inverter;
> The installation position shall be convenient for maintenance;
> Ambient temperature range: –25°C
~
55°C;
> Appropriate space shall be reserved for the machine to ensure ventilation and
cooling.
We suggest inverter is installed in the distribution room. The floor, wall clearance,
Ventilation equipment and precaution should be designed by professional personnel
and satisfy the following requirements.
[Foundation requirement]
Inverter is required to install on even ground with fire-retardant material as the
surface or channel steel support structure, and sag or tilt ground is prohibited. The
foundation shall be solid, safe and reliable. The foundation shall be capable of
bearing the load of the inverter. Its load bearing ability shall be concerned
throughout the installation place selection.
[Clearance space]
During installation of the inverter, appropriate space shall be left to the wall or other
equipment, in order to satisfy the requirements on narrowest maintenance channel,
emergency access and ventilation.
[Cable trench]
The cable connection of inverter adopts bottom inlet and bottom outlet. Cable
trenches are recommended.
The cable trenches are often designed and constructed by the construction side
based on relevant standards, with the equipment weight and dimensions required to
be considered. Good electrical connection is needed between different cable
trenches and GND terminals.
[Wiring specification]
Cables in the inverter can be classified into either power cables or data cables.
In cabling, the power cable shall be kept far away from, and the cable shall be kept in
right angle at cross. The cable shall be as short as possible, and an appropriate
distance shall be kept to the power cable.
The power cable and data access shall be placed in different cable trenches
respectively to avoid lengthy routing between the power cable and other cables, so
as to reduce the electromagnetic interruption caused by sudden change of the
output voltage. The distance among the power cable and data access shall be more
than 0.2m. When the cables are crossed, the cross angle shall be 90 degrees, while
the distance can be reduced appropriately.
[Ventilation requirement]
In operation, inverter will produce a lot of heat. When ambient temperature is too
high, the electrical property of the equipment may be affected, the equipment may
even be damaged. Therefore, the heat release shall be fully considered in designing
the control room to ensure operation of the equipment in high efficiency.
In front of the installation place of inverter, a space of 1.5m or more shall be ensured,
the back 0.6m or more, the top 0.6m or more to ensure easy installation, cooling and
maintenance.
[Ventilation environment]
To satisfy the ventilation requirement of inverter, its installation environment shall
meet the following conditions:
Inverter shall be prevented from being installed in the place of poor ventilation
condition and insufficient air flow;
The air inlet shall have enough air supplementation.
