Installation
Explosive, flammable gases
As the inverter is non-explosion proof, it must be contained in an explosion proof enclosure.
In places where explosion may be caused by explosive gas, dust or dirt, an enclosure cannot be used
unless it structurally complies with the guidelines and has passed the specified tests. This makes the
enclosure itself expensive (including the test charges).
The best way is to avoid installation in such places and install the inverter in a non-hazardous place.
Highland
Use the inverter at the altitude of within 1000 m.
If it is used at a higher place, it is likely that thin air will reduce the cooling effect and low air pressure
will deteriorate dielectric strength.
Vibration, impact
The vibration resistance of the inverter is up to 5.9 m/s² at 10 to 55 Hz frequency and 1mm amplitude
for the directions of X, Y, Z axes.
Vibration or impact, if less than the specified value, applied for a long time may make the mechanism
loose or cause poor contact to the connectors.
Especially when impact is imposed repeatedly, caution must be taken as the part pins are likely to
break.
● Countermeasures
– Provide the enclosure with rubber vibration isolators.
– Strengthen the structure to prevent the enclosure from resonance.
– Install the enclosure away from sources of vibration.
