General
GCK should be an improved economical type of MNS. The vertical row has no plastic functional panels. The door is fixed on the frame. After the door is opened, the drawer can be pulled out. G--cabinet structure; C--drawable type; K--control center
Working environment
1. The ambient air temperature should not be higher than +40℃, not lower than -5℃, the average temperature within 24h should not be higher than +35℃ if it exceeds, it needs to be derated and run according to the actual situation;
2. Indoor use: the altitude of the place of use shall not exceed 2000m
3. The relative temperature of the surrounding air should not exceed 50% when the temperature is +40℃. A larger relative temperature is allowed at a lower temperature, such as 90% when the temperature is +20℃. It should be considered that condensation may occur accidentally due to temperature changes. The impact of exposure;
4. When the device is installed, the inclination from the vertical plane does not exceed 5°C, and the entire group of cabinets is relatively flat (in accordance with the GBJ232-82 standard);
5. The device should be installed in a place where there is no severe vibration and impact, and where the electrical components are not corroded;
6. If the user has special requirements, it can be resolved through consultation with the manufacturer.
