When mounting two or more inverters
When mounting two or more inverters in the same unit or panel, basically lay them out side by
side. As long as the ambient temperature is 40°C or lower, inverters can be mounted side by
side without any clearance between them. When the inverters necessarily mounted 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.
(3) Mounting direction
Secure the inverter to the mounting base with four screws or bolts (M4) so that the FVR-Micro logo
faces outwards. (FVR0.4AS1S-7 and
FVR0.75AS1S-7 use two screws or bolts.) Tighten those
screws or bolts perpendicular to the mounting base. (Maximum torque is 0.6N∙m)
Do not mount the inverter upside down or horizontally. Doing so will reduce the
heat dissipation efficiency of the inverter and cause the overheat protection function to
Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting
into the inverter or from accumulating on the heat sink.
This may result in a fire or accident.
3. Wiring
Follow the procedure below. (In the following description, the inverter has already been installed.)
3.1 Removing and mounting the terminal block covers
(1) Loosen the screw securing the control circuit terminal block cover.
(2) Insert your finger in the cutout (near "PULL") in the bottom of the control circuit terminal
block cover, and then pull the cover towards you.
(3) Hold both sides of the main circuit terminal block cover between thumb and forefinger and
slide it towards you.
(4) After performing wiring, mount the main circuit terminal block cover and control circuit
terminal block cover in the reverse order of removal.
