INSTALLATION AND WIRING

2.1.1Instructions for installation

1)Handle the unit carefully.

The inverter uses plastic parts. Handle it gently to protect it from damage. Also, hold the unit with even strength and do not apply too much strength to the front cover alone.

2)Install the inverter in a place where it is immune to vibration. (5.9 m/s2 or less) Also note the cart, press, etc.

3)Note on ambient temperature

The inverter life is under great influence of ambient temperature. In the place of installation, ambient temperature must be within the permissible range (depending upon the operation mode and conditions (see ambient temperature specifications on page 187). Check that the ambient temperature is within that range in the positions shown in figure 3)).

4)Install the inverter on a non-combustible surface.

The inverter will be very hot (maximum about 150° C (302° F)). Install it on a non-combustible surface (e.g. metal). Also leave sufficient clearances around the inverter.

5)Avoid high temperature and high humidity.

Avoid direct sunlight and places of high temperature and high humidity.

6)The amount of heat generated in an enclosure can be reduced considerably by placing the heat sink outside the enclosure.

Note: 1. Use the option (FR-A5CN"") for installation. The mounting area should be cut to the panel cutting dimensions.

2.The cooling section outside the enclosure has the cooling fan. Do not use the inverter in any environment where it is exposed to waterdrops, oil mist, dust, etc.

7)Avoid places where the inverter is exposed to oil mist, flammable gases, fluff, dust, dirt etc. Install the inverter in a clean place or inside a "totally enclosed" panel, which does not accept any suspended matter.

8)Note the cooling method when the inverter is installed in an enclosure.

When two or more inverters are installed or a ventilation fan is mounted in an enclosure, the inverters and ventilation fan must be installed in proper positions with extreme care taken to keep the ambient temperatures of the inverters below the permissible value. If they are installed in improper positions, the ambient temperatures of the inverters will rise and ventilation effect will be reduced.

9)Install the inverter securely in the vertical direction with screws or bolts.
