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.
Table 2.1 Environmental Requirements
Item Specifications
Site location Indoors
Ambient -10 to +50 C
(Note 1)
temperature
Relative 5 to 95% (No condensation)
humidity
The inverter must not be exposed to dust,
Atmosphere
direct sunlight, corrosive gases, flammable
gas, oil mist, vapor or water drops.
The atmosphere must contain only a low
level of salt.

(0.01 mg/cm or less per year)
The inverter must not be subjected to sudden
changes in temperature that will cause con-
densation to form.
Altitude 1,000 m max.

2.2 Installing the Inverter

(1) Mounting base
The temperature of the heat sink will 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 constructed from
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 enclosure of your
system, take extra care with ventilation inside the
enclosure as the temperature around the inverter
will tend to increase.

(Note 1)
side-by-side without any gap between them
or the NEMA1 kit option is mounted on the
inverter, 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 environment,
install it in the enclosure of your system or
other dustproof containers.
9 to less than 20 Hz
(Note 3) If you use the inverter in altitude
20 to less than 55 Hz
above 1000 m, you should apply an output
55 to less than 200 Hz
current derating factor as listed in Table 2.2.
