The MegaFlex 1000to 1600 UPS can radiate radio frequencyenergy.
Although some RFI (Radio Frequency Interference) filtering is inherent to the UPS there is no guarantee that the
UPS will not influence sensitivedevices such ascameras andmonitors that are positioned closeby.
If interference is expected, the UPSshould be moved away from the sensitive equipment.
4.4.2 Later commissioning
It’s not recommended to unpack UPS until commissioning can be performed. In any case, care must be taken to
prevent foreign object to fall into UPS openings (e.g. debris due to construction works or fasteners). Do not
perform construction work over the UPS cabinet.
4.4.3 Altitude
Maximum altitudeof installation without derating is 3300 ft(1000m).

Positioning of the UPS
The rear panel of the UPS may be mounted flush to a wall or
other structure.
Clearance around the front of the unit should be sufficient
to enable free passage of personnel with the doors fully
open, andto allowsufficient airflowto the door vents.
Check Section 110-
26(A) of the NEC code for specific
requirements.
To guarantee proper cooling air exhaust, the
mandatory
minimum clearance between ceiling and top of the UPS is
18” (460 mm).
A single-phase power outlet (120Vac) should be provided
near the UPS for connection of power tools, test
equipment orconnectivity devices.
This outlet must be grounded.

Fig. 4.4.5-5 MegaFlex 1000 to 1600 – RPA Parallel System disposition
In case of Parallel System, try to place the UPS modules in sequence of their numbers (marked
on the packing).
If the units are positioned “side by side”, the side panels must bemounted on allunits.
Remove the side air inlet grids on the intermediate units to run the control bus cable
connections.
4.4.6 Battery location
Batteries require a well-ventilatedroom with controlled temperature to obtain reliable operation.
The Battery canbe installed immediately adjacent to the UPS (left or right side) or remotely from theUPS.
If the Battery is installed remotely from the UPS, a wall mounted DC disconnect device must be installed within
line-of-site to both the UPS andthe Battery.
The optimal room temperature for Batterystorage is 68°F (20°C) to 77°F (25°C) andshall neverexceed the range -
4°F (-20°C) to 104°F (40°C).
The life of valve-regulated Battery will be reduced by 50% for each additional 18°F (10°C) that the Battery ambient
temperature is above 77°F (25°C).
The Battery System associated with larger UPS is usually either rack mounted or installed in multiple Battery
Cabinets.
Installation and assembly must be made according to the local standards and Battery System manufacturer‘s
recommendations.
The Battery Circuit Breaker mustbe mounted asnear as possible to the Battery.
Warning!
Battery installation and connection must be performed by Qualified Personnel only.
Read all safety instructions before proceeding with the installation (see Chapter 1).
Battery discharging and/or charging activities may cause the emission of hydrogen gas; therefo
re,
the room requires proper ventilation and fresh air.
Comply with the UL1778-
CSAC22.2no170.3 UPS safety standard, ANSI/IEEE P1184 Guide for
Batteries for Uninterruptible Power Supply Systems and applicable codes and governmental
regulations.

4.5 Ventilation and cooling
Fig. 4.5-1 Installation on plain floor Fig. 4.5-2 Installation on raised floor
The heat produced by the UPS is transferred to the environment by its ventilation.
Air inlets for UPS ventilation are located on the front of the UPS, while air outlets are on top of the cabinet.
A suitable ventilation or cooling system must be installed to extract the heat from the UPS room.
Note!
Do not put anything on the top of the cabinet.
18”(460mm) of air clearance from the top must be left free of any object for a sufficient exhausted
air exchange, proper cooling, service access and safety.
Air filtering systems could be required when the UPS operates in a dirty environment.
In order to prevent overheating of the UPS, the available air intake flow rate must exceed the total air exhaust
flow rate requirement of the UPS system.
Contact your ABB Service Center for appropriate solutions.
