3. Precautions on Usage

(1) In an environment where the FRENIC-Mini may be subjected to vibration or impact, the FRENIC-Mini installed to a din rail is

NOT recommended.

(2) Installation of the FRENIC-Mini with a rail mounting base is allowed only when the FRENIC-Mini is installed vertically.

(3) When installing the FRENIC-Mini series of inverters together with other devices on the same din rail, keep a space of at least 10

mm(0.4 in) between components. However, as long as you are installing the FRENIC-Mini series of inverters only and the ambient
temperature is 40ºC(104ºF) or below, side-by-side installation of the inverter without a gap is possible.

4. Installation Procedure

(1) Installing a rail

Secure a din rail (on which you want to set up your

FRENIC-Mini) with mounting screws at intervals of
a maximum of 200 mm(8 in) 100 mm(4 in) or less
recommended).

Installing the rail mounting base with the FRENIC-Mini to the din rail
（See Figure 2.）

1) Hook the upper latches of the rail mounting base over the upper edge
of the din rail. The RMA-C1-3.7 has four upper latches, make sure that
all of the four latches catch the upper edge of the din rail.

2) Press the lower end of the FRENIC-Mini against the din rail until the
lower latches of the rail mounting base catch the din rail.

Removing the rail mounting base with the FRENIC-Mini from the din rail
（See Figure 3.）

1) W hile holding the FRENIC-Mini by hand,

pull down the handle of the
rail mounting base and pull the lower end of the FRENIC-Mini
towards you to release it from the lower latches of the din rail.

CAUTION Be sure to support the FRENIC-Mini while

removing. Failure to do so might allow the FRENIC-Mini to fall.
