3.2.2 MINIpowerPLUS Rack-mounted versions
Rack positioning and accessibility
The MINIpowerPLUS Rack-mounted UPS cabinet
is designed to fit into a standard 19 inch rack and
is 6U high. The cabinet is fitted through the front
of the rack, supported on suitable rails and
secured in position by means of two screws on
each side of the front of the assembly.
All MINIpowerPLUS 5000 Rack-mounted UPS
cabinets also contain the UPS batteries; however
a matching rack-mounted battery cabinet is
available if an extended battery facility is required.
Where used, the separate battery cabinet (also
6U) and UPS cabinet should preferably be fitted in
the same rack and positioned immediately
adjacent to each other.
Due to the weight of the assembly it is usual to
mount the UPS cabinet and optional battery
cabinet (where used) near the bottom of the rack.
There is no minimum space requirement above or
below the UPS cabinet when it is in-situ, but a
minimum of 200mm should be provided at the
rear of the unit to allow for adequate cooling air
flow and facilitate cabling. As the UPS cabinet is
600mm deep this implies a minimum rack depth of
800mm.
As mentioned above, rear access is required for
cabling therefore sufficient room should be
provided behind the rack to permit easy passage
– recommended 900mm. A similar space is
required at the front of the rack to enable the UPS
cabinet to be handled while it is being installed.
3.2.3 Environmental considerations
The following conditions apply to both Tower and Rack-mounted installations.
• The UPS location should be subject to a humidity of less than 90% (non-condensing) and temperature
b15°C to +25°C. An ambient temperature of 20°C is recommended for optimum battery life.
• The location should be free from dust or corrosive/explosive gases.
• The location should not be subject to vibration.
• The air conditioning system must be able to provide a sufficient amount of cooling air to keep the room
at, or below, the maximum permissible operating temperature.
CAUTION: The UPS cabinet is heavy.
Ensure that sufficient personnel and
appropriate handling equipment are
available to install the unit safely.
