Lighting
Lighting in equipment room may be classified into general lighting and partial lighting. General lighting provides light
for the whole room, while partial lighting is installed above the equipment cabinet or workstation to provide light for a
restricted area. It is recommended to provide both lightings in the equipment room.
Clearance
1. At least 1.5m of clearance should be kept between the front of the power system cabinet and the wall.
2. At least 0.8m of clearance should be kept between the back of the power system cabinet and the wall.
3. At least 0.8m of clearance should be kept the sides of the power system cabinet and the wall.
4. At least 1.5m of clearance should be kept between the back of the power system cabinet and the front of another
piece of equipment.
5. At least 1.2m of clearance should be kept between the back of the power system cabinet and the back of another
piece of equipment.
6. Maintenance passage should be kept between equipment, which should not be less than 2m wide.
Refer to Figure 2-1 for the above requirements. No less than 0.2m of clearance should be kept between the battery
and the wall, and no less than 0.8m of clearance should be kept between batteries.

Weight capacity and shockproof requirements
When installing the power system in areas subject to frequent earthquakes, shockproof measures should be taken.
Firstly, expansive bolts should be used to fix the system (refer to
); secondly, the system
should be reinforced as shown in Figure 2-2 to enhance its shockproof ability. Because the power supply system is
relatively heavy, the weight capacity of the equipment room should meet relative requirements and is determined
based on the equipment configuration.

Fire protection facility
The equipment room should comply with relevant fire protection regulations and requirements for power distribution,
and provide adequate fire protection facility, such as dry-chemical extinguisher and automatically explosive fire
protection ball.
