Installation
2.1 Installation
2.1.1 Instructions for installation
1) Handle the unit carefully.
The power regeneration common converter 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 terminal block cover alone.
2) Install the inverter in a place where it is immune to vibration. (5.9 m/s
2
or less)
Also note the cart, press, etc.
3) Note on ambient temperature
The power regeneration common converter life is under great influence of ambient temperature. Exercise care
so that the ambient temperatures of the installation place do not fall out of the permissible range (-10°C to
+50°C (14°F to 120°F)). Make sure that the ambient temperatures are within the permissible range at the
measurement positions given in 3) on the next page. It is important to check that not only the ambient
temperatures of the power regeneration common converter but also those of the inverter contained in the same
enclosure fall within the permissible range.
4) Notes on installation surface
The power regeneration common converter will be very hot (maximum about 150°C (302°F)).
The power regeneration common converter (heat sink outside mounting structure model) can be reduced in the
enclosure inside temperature by mounting its heat sink outside the enclosure. Cut the mounting area according
to the panel cutting dimensions. Since the cooling section located outside the enclosure has a cooling fan, do
not use the equipment in the environment that has water drops, oil mists, dust particles, etc. For installation in
an enclosure, use the enclosure inside installation structure model of the power regeneration common
converter and install it on an incombustible (e.g. metal) mounting surface.
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) Avoid places where the inverter option is exposed to oil mist, flammable gases, fluff, dust, dirt etc.
Install the inverter option in a clean place or inside a "totally enclosed" panel which does not accept any
suspended matter.
7) Note the cooling method when the power regeneration common converter and inverter is installed in an
enclosure.
When two or more power regeneration common converters and 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 power regeneration common converters and inverters
below the permissible value. If they are installed in improper positions, the ambient temperatures of the power
regeneration common converters and inverters will rise and ventilation effect will be reduced.
8) Install the power regeneration common converter and inverter securely in the vertical direction with screws or
bolts.
9) Install the dedicated stand-alone reactor (FR-CVL) on horizontal plane. Failure to observe this may lead to
damage of the reactor.
