5.1 Mounting and Wiring the Inverter

5.1.1

Installing the inverter

(1) Mounting base
Install the inverter on a base made of metal or other non-flammable material. Do not mount the inverter
upside down or horizontally.
Install the inverter on a base made of metal or other non-flammable material.
Otherwise, a fire could occur.
(2) Clearances
Ensure that the minimum clearances indicated in Figure 5.1 and
Table 5.1 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 ambient temperature easily rises. Do not install the
inverter in a small panel with poor ventilation.
 Mounting two or more inverters
When mounting two or more inverters in the same unit or panel,
basically lay them out side by side. When mounting them
necessarily one above the other, be sure to separate them with a
partition plate or the like so that any heat radiating from an inverter
will not affect the one(s) above.
