1.4 SITE PLANNING AND POSITIONING
1.4.1 PLANNING BEFORE THE INSTALLATION
The equipment must be installed and transported in a upright position. The equipment requires space to
bottom/front and back to enable cooling airflow. It is required to arrange ventilation of the UPS room.
All parts of the UPS for service and user access are accessible from the front and rear, making it a service-friendly
and maintenance-friendly UPS. Reserve enough space from the front (min. 900 mm)
The UPS should be installed inside a room where:
Humidity
and temperature don’t exceed the limits: humidity =< 95 % non-condensing and temperature
between 0°C and +40°C. However an ambient temperature of +20°C to +25°C is recommended to
achieve a long life of the UPS and batteries
Fire protection standards are respected
Cabling can be performed easily
On cabinet A and B front, rear and side access is necessary for service and maintenance. On cabinet
C front and side access is necessary for service and maintenance. Side access required for battery
service
Requested air cooling flow should be granted. The cooling air entering the UPS must not exceed
+40°C.
The air conditioning system should have sufficient amount of air cooling needed to keep the max. room
temperature rise at desired level
Dust or corrosive/explosive gases must be absent
The place is vibration free
The floor material should be non-flammable and strong enough to support the heavy physical load
1.4.2 POSITIONING OF UPS AND BATTERY CABINET
1.4.2.1
Final Transport
Check before transporting the surface loading and use a adequate forklift to move the equipment to the final
position.
1.4.2.2
Positioning
UPS :
A minimum 200 mm rear space from the UPS to an obstruction is recommended for proper cooling as
the air enters at bottom/front and exits at unit rear (see Fig. 1 and 2)
External Battery :
It’s recommended to install external battery cabinet(s) next to the UPS unit. The external
battery is recommended to be placed on left hand side of the UPS unit.
Check before the installation that the battery voltage values in the type plate of the UPS and external battery
cabinets are the same.
WARNING!
THE UPS CONTAINS HIGH DC VOLTAGES. A QUALIFIED PERSON MUST DO
THE CONNECTIONS BETWEEN THE UPS AND THE EXTERNAL BATTERY
CABINET(S). THE BATTERY CABINET IS CONNECTED ELECTRICALLY IN
PARALLEL WITH THE INTERNAL BATTERIES OF THE UPS.
