Mounting Position; Ventilation Within An Enclosure; External Cooling Of Inverter - Hyundai N700E Instruction Manual

N700E INSTRUCTION MANUAL

(6) Mounting Position

Mount the inverter in a vertical position using screws or bolts. The mounting surface should also be
free from vibration and can easily hold the weight of the inverter.

(7) Ventilation within an Enclosure

If you are installing one or more inverters in an enclosure a ventilation fan should be installed.
Below is a guide to the positioning of the fan to take the airflow into consideration. The positioning
of inverter, cooling fans and air intake is very important.
If these positions are wrong, airflow around the inverter decreases and the temperature
surrounding the inverter will rise. So please make sure that the temperature around is within the
limit of the allowable range.

(8) External cooling of inverter

It is possible to install the inverter so that the heatsink is outside of the back of the enclosure. This
method has two advantages, the cooling of the inverter is greatly increased and the size of the
enclosure will be smaller.
To install it with the heatsink outside of the enclosure, a metal fitting option is required to ensure
heat transfer. Do not install in a place where water, oil, mist, flour, and/or dust etc. can come in
contact with the inverter as there are cooling fans fitted to the heatsink.
