9 Installation 9.1 Installation precautions 1) When installing the inverter, the user shall check whether the power grid feed line connected to the inverter is unblocked in advance, including whether the contact of each contact and grounding socket is good, so as to avoid introducing open circuit or short circuit fault. 2) When installing the inverter, the user shall not connect the zero line, live line and ground wire output by the inverter reversely or wrongly, so as to avoid electrical short circuit;At the same time, check whether the input mains voltage is normal. 3) Inverter installation requirements: Place the inverter flat on the ground (avoid inclined and uneven ground).
Do not place objects above the inverter, nor do personnel sit on it. Avoid placing in sunny, rainy or humid places. Do not place in a place containing corrosive gas Figure 9-1 Inverter placement requirements 9.2 Site environmental requirements 1) Sundries and garbage shall not be stacked around the inverter. Droplets and metals accidentally dropped or placed may cause short circuit and endanger the system and personal safety.Dust, dirt or sundries on the inverter exhaust hole will hinder air circulation and affect the cooling effect of the fan.This causes the system to shut down due to excessive temperature.
2) The civil construction of the machine room shall be completed and the floor has hardened.The site shall be clean, dry and free of dust. 3) It is strictly prohibited to store inflammable, explosive and other dangerous articles in the machine room. 4) In order to reduce the possibility of fire and reduce the damage caused thereby, the walls, ceilings and floors of the room where the inverter is placed shall be made of fireproof materials and equipped with applicable and effective fire-fighting equipment (such as portable CO2 fire extinguisher).
5) In order to facilitate operation and maintenance and equipment heat dissipation, at least 30 ~ 50cm space shall be reserved around the frame and 50cm space shall be reserved at 15
