302 Installation and Service Clearances
Note:
If you use flexible conduit to connect the UPS and battery cabinets, you may be able to achieve the
service clearances by moving the UPS. If this is true, you must still leave 4 in. (100 mm) on the sides,
front, and back for ventilation. See Section 901 for UPS dimensions.
303 Location Requirements
• Install the UPS as close as possible to the equipment it will protect. If this distance is more than 25 feet (7.6
meters), transient noise can reappear in the electrical distribution system.
• If the UPS batteries are in a separate cabinet, the battery cabinet should be as close to the UPS as possible. If
the batteries will be farther away from the unit than the standard cables allow, call the nearest Best Power
office for assistance.
• The UPS should be in a flat location in a controlled, indoor environment. (See Section 904 for operating
environment specifications.) Keep the UPS away from heat sources, direct sunshine, moisture or corrosive
gas. Do not install the UPS next to open windows. Do not place any objects on top of the UPS, and do not
install it in any type of enclosure. Do not operate the UPS or batteries in a sealed room or container.
304 AC Installation
The UPS installation must be performed by qualified personnel according to local codes and regulations.
1. Find the UPS ID label on the back panel, and note the model number: ______________________________
2. The UPS can accept an input voltage from 176-276 VAC, and it can provide these output voltages: 104/208,
110/220, 115/230, and 120/240. (The output voltage depends on the setting of the DIP switch. See Section
306.) Make sure the input voltage at the Service panel fits within the input voltage range listed above, and
make sure that the output voltage your equipment requires matches one of the possible selections for the
UPS. If not, call the nearest Best Power office.
3. Move the UPS and any battery
cabinets into their permanent
location. Then, follow the
instructions for your model:
B6106000:
At the UPS, you will find
a leveler next to each caster.
Using a wrench, turn each
leveler to lower it and keep
the UPS from moving. Next,
find the 4 brackets that were
packed under the UPS and
each optional battery cabinet.
Attach two brackets to each
side of the UPS and each
battery cabinet as shown to
stabilize each cabinet.
