
The equipment room should be at least 5 km away from heavy pollution sources, such as the smel ter 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 wa rehouse 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, kee p the door
and window away from the pollution source.

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 electromag netic 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.
