Chapter 2 MOUNTING AND WIRING OF THE INVERTER
2.1 Operating
Environment
Install the inverter in an environment that satisfies the requirements listed in Table 2.1.

Ambient
temperature
-10 to +50
°

(Note 1)
Relative
humidity
5 to 95% (No condensation)
Atmosphere
The inverter must not be exposed to dust,
direct sunlight, corrosive gases, flammable
gas, oil mist, vapor or water drops.
(Note 2)
The atmosphere can contain only a low level
of salt.
(0.01 mg/cm

The inverter must not be subjected to sudden
changes in temperature that will cause
condensation to form.

2.2 Installing the Inverter
(1) Mounting
base
The temperature of the heat sink may rise up to
approx. 90°C during operation of the inverter, so
the inverter should be mounted on a base made of
material that can withstand temperatures of this
level.
Install the inverter on a base made of metal or
other non-flammable material.
A fire may result with other material.
(2) Clearances
Ensure that the minimum clearances indicated in
Figure 2.1 are maintained at all times. When
installing the inverter in the panel of your system,
take extra care with ventilation inside the panel as
the temperature around the inverter tends to
increase.

(Note 1)
When inverters are mounted
side-by-side without any gap between them,
the ambient temperature should be within
the range from -10 to +40
°
C.
(Note 2)
Do not install the inverter in an
environment where it may be exposed to
cotton waste or moist dust or dirt which will
clog the heat sink in the inverter. If the
inverter is to be used in such an environ-
ment, install it in the panel of your system or
other dustproof containers.
(Note 3)
If you use the inverter in an altitude
above 1000 m, you should apply an output
current derating factor as listed in Table 2.2.
