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(104°F) or lower, inverters can be mounted side by side
without any clearance between them. When mounting the inverters 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.
(3) Mounting direction
Secure the inverter to the mounting base with four screws or bolts (M4) so that the FRENIC-Mini logo
faces outwards. Tighten those screws or bolts perpendicular to the mounting base.
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 operate,
so the inverter will not run.
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.
2.3 Wiring
Follow the procedure below. (In the following description, the inverter has already been installed.)
2.3.1 Removing the terminal block (TB) covers
(1) Removing the control circuit terminal block (TB) cover
Insert your finger in the cutout (near "PULL") in the bottom of the control circuit TB cover, then pull
the cover towards you.
(2) Removing the main circuit terminal block (TB) cover
Hold both sides of the main circuit TB cover between thumb and forefinger and slide it towards you.
