5 Intrinsically Safe Power Output Parameters (see Table 1): 

The Control Box mainly consists of the main explosion-proof chamber, human-machine operation LCD touch screen, incoming and outgoing wiring chamber and intrinsically safe chamber. The upper part includes the main chamber and wiring chamber, and the lower part is the intrinsically safe chamber. The main explosion-proof chamber adopts a bolt fastening structure, so as to facilitate equipment installation, adjustment and maintenance. The PLC module is installed at the front of the master control explosion-proof box, and the power module box at the lower. The operation button and extra-large LCD touch screen are installed at the front door panel, and the operation interface is simple and friendly. The voice module, horn and wiring terminal are installed in the intrinsically safe chamber.

c) The ambient relative humidity shall not be larger than 95% (at +25℃/77oF);

d) In the mine shaft with methane-air mixture

e) At the place without significant vibration or impact

f) At the place without water drip

g) Horizontal installation (the inclination does not exceed 15°)
