1.3 INSTALLATION AND WIRING
1.3.1 Precautions for installation
(1) Installation of the high power factor converter
Instructions for ambient temperatures
The lives of the high power factor converter and
reactors 1, 2 are affected considerably by ambient
temperatures. Keep their ambient temperatures
below the permissible value (50°C). Measure the
ambient temperatures in the following positions to
make sure that they are within the permissible
range.:
Leave sufficient space around the equipment.
For adequate heat dissipation, leave sufficient
space around the high power factor converter.
It is possible to place the heat sink outside the
enclosure to greatly reduce heat generated.
Incorrect handling might cause the equipment to operate improperly, its life to be reduced
considerably, and in the worst case, the high power factor converter and inverter to be
damaged. Please handle the unit properly in accordance with the information on each
section as well as the precautions and instructions of this manual.
Note: 1.When the high power factor converter is
installed in a panel, determine the cooling
method and panel dimensions so that the
ambient temperature of the high power factor
converter is within the permissible range
(specified value is given on page 56).
2.When the inverter and high power factor
converter are installed in the same panel or a
ventilation fan is mounted in the panel,
extreme care must be taken to keep the
ambient temperatures of the high power factor
converter and inverter below the permissible
value. If the high power factor converter,
inverter and/or ventilation fan is installed in an
improper position, the ambient temperature of
the high power factor converter will rise and
ventilation effects will reduce.

Note: 1.Use the optional mounting bracket (FR-ACN)
(see page 70). The mounting area should be
machined to the panel cutting dimensions on
page 66.
2.The cooling section outside the panel has a
cooling fan. Do not use the inverter in damp,
oil mist or dust environments.
