Site Selection
⚫
The equipment room should be at least 5 km away from heavy pollution sources, such as the smelter works,
coal mine, and thermal power plant. The equipment room should be at least 3.7 km away from medium
pollution sources, such as the chemical factory, rubber factory, and electroplating factory. The equipment
room should be at least 2 km away from light pollution sources, such as the food factory and leather plant. If
these pollution sources are unavoidable, the equipment room should be located on the windward side of the
pollution sources perennially with advanced protection.
⚫
The equipment room should be at least 3.7 km away from the sea or salt lake. Otherwise, the equipment
room must be sealed, with air conditioner installed for temperature control. Saline soil cannot be used for
construction. Otherwise, you should select devices with advanced protection against severe environments.
⚫
Do not build the equipment room in the proximity of livestock farms. Otherwise, the equipment room should
be located on the windward side of the pollution source perennially. The previous livestock house or fertilizer
warehouse cannot be used as the equipment room.
⚫
The equipment room should be firm enough to withstand severe weather conditions such as windstorm and
heavy rain. The equipment room should be away from the dusty road or quarry. If the dust is unavoidable,
keep the door and window away from the pollution source.
⚫
The equipment room should be away from the residential area. Otherwise, the equipment room should meet
the construction standard in terms of noise.
⚫
Make sure that the air vents of the equipment room are away from the sewage pipe, septic tank, and
sewage treatment tank. Keep the equipment room under positive pressure to prevent corrosive gas from
entering the equipment room to corrode components and PCBs.
⚫
Keep the equipment room away from industrial boilers and heating boilers.
⚫
The equipment room had better be on the second floor or above. Otherwise, the equipment room floor
should be 600 mm higher than the highest flood level ever recorded.
⚫
Make sure there are no cracks or holes on the wall and floor. If there are cable entries on the wall or window,
take proper sealing measures. Ensure that the wall is flat, wear-resistant, and dust-free, which should be up
to the standard for flame retarding, soundproofing, heat absorption, dust reduction, and electromagnetic
shielding.
⚫
Keep the door and the window closed to make the equipment room sealed.
⚫
The steel door is recommended for soundproofing.
⚫
Sulfur-containing materials are forbidden.
⚫
Keep the air conditioner from blowing wind straight toward the switch.
