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.

Site location Indoors
Ambient
temperature
-10 to +50
C (14 to 122

Atmosphere The inverter must not be exposed to dust,
direct sunlight, corrosive gases, flammable
gas, oil mist, vapor or water drops.

The atmosphere can contain only a low level
of salt.

changes in temperature that will cause
condensation to form.

Otherwise a failure could occur.
2.2 Installing the Inverter
(1) Mounting base
The temperature of the heat sink may rise up to approx.
90°C (194
F) 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.

(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 (14 to 104
F).
(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 (3300 ft), you should apply an
output current derating factor as listed in
Table 2.2.
