4.2.3 Installation space
Maintain a clearance of at least 800 mm. from the front panel, side panel or rear panel of the UPS to the wall or
adjacent device, and maintain a clearance of at least 800 mm. from the top of the UPS to ceiling to ensure good
ventilation, as shown in Figure 4-2.
•
Avoid any block to the ventilation hole on the front panel and rear panel, to keep good ventilation for the
UPS, or, it may rise the inner temperature, and even influence the UPS service time.
4.2.4 Selection for input and output wires
For the wire sectional area selection of AC input and output wires, please refer to Table 4-1 for corresponding
recommended values, and choose upwards.
4.2.2 Installation environment
•
Do not install the UPS in the place which exceeds the provision of technology index (temperature: 0
0C~40 0C, relative humidity: 0%~95%).
•
It is strictly prohibited to install the UPS in the environment with metal conductive dust.
•
Do not install the UPS in the open air, and the installation environment should meet the
provision requirements.
•
Basic requirements for power supply:
− Grounding preparation. Ensure that the grounding terminal is OK and the voltage between
neutral wire and grounding wire should not exceed 5 V.
− Before installation, please ensure that the AC input voltage and mains input wire capacity meet
the UPS requirements. And considering if there is current-carrying capacity descending caused
by wire aging.
− The mains input voltage range of the UPS is 80 VAC-280 VAC. The mains capacity should be
greater than the max. input power of the UPS.
− The selected breaker should not be installed without leakage current protection.
•
The installation environment of the UPS should be with good ventilation, and far away from water, heat
sources, inflammable and explosive objects. Avoid installing the UPS with direct sunshine, dust, volatile
gas, corrosive objects or high salinity.
•
The UPS is suitable for using below 1000 m. If the altitude exceeds 1000 m, it needs to decrease the
rated power according to GB/T3859.2
The optimal operating temperature for batteries is 20–30 °C.
Operating at temperatures lower than 20 °C will shorten the battery
backup time, and operating at temperatures higher than 30 °C will
shorten the battery lifespan.
For safety, make sure that the external DC distribution circuit is
configured with a bi-polar disconnecting switch.

Note:
The installation space requirement of 40 kVA series UPS is the same. In the above figure, we take
40 kVA UPS as an example to illustrate.
