4 INSTALLATION AND WIRING
4.1 POSITIONING OF THE UPS AND BATTERY CABINET
The UPS is designed for location in a restricted access location only and should be located where:
•
The relative humidity does not exceed 95% (non-condensing) and the temperature remains always between
0°C and +40°C. Note: an optimal temperature for the UPS and especially for VRLA batteries is 20°C- 25°C.
The UPS room shall have temperature control (air-cooling)
•
Any kind of dust or corrosive/explosive gases must be absent
•
Fire protection standards are respected
•
The place is vibration free
•
The floor material should be non-flammable and strong enough to support the heavy load.
•
Cabling can be performed easily
•
Available front accessibility of 1m from front of the unit for service or maintenance
•
Only front access is necessary for service and maintenance
•
If the UPS will be installed in bayed enclosures, partition walls have to be installed as well
Also the needed clearances to allow proper airflow on the UPS system and to allow proper service and
maintenance shall be respected as reported in the Tables 5 and 6 here below.
