■ Installation with external cooling
The external cooling installation reduces the generated heat inside the
panel by dissipating approximately 70% of the total heat generated (total
heat loss) by mounting the cooling fins protruding outside the equipment
or cabinet. The external cooling unit body has a protective construction
of IP55.
Installation with external cooling is possible for inverters FRN0115G2S-
2G / FRN0060G2□-4G or lower with the addition of an external cooling
attachment (option), and for FRN0146G2S-2G / FRN0075G2□-4G or
higher by moving the mounting base.
(Refer to Chapter 11 “11.16 External Cooling Fan Attachments” for details
on external cooling attachments.)
Take measures to prevent foreign material such as lint, wastepaper,
wood shavings, dust, or metal scraps getting into the inverter, or
adhering to the cooling fan.
Failure to observe this could result in fire or an accident.
