Safety Requirements for Rack Installation
The following safety requirements must be considered when the InfiniteStorage 6120 is mounted in
a rack.
The rack when configured with the units must meet the safety requirements of UL 60950 and IEC
60950.
Mechanical Loading
• The mounting of the system must conform to even and safe mechanical loading. Uneven
mechanical loading could cause a rack to tip and fall.
• The rack construction must be capable of supporting the total weight of the installed
enclosure(s) and the design should incorporate stabilizing features suitable to prevent the rack
from tipping or being pushed over during installation or in normal use.
• When loading a rack with the units, fill the rack from the bottom up and empty from the top
down.
• Always remove all modules and drives, to minimize weight, before loading the chassis into a
rack.
WARNING : It is recommended that you do not slide more than one enclosure out
of the rack at a time, to avoid danger of the rack tipping over.
• When mounting in a rack, ensure that the enclosure is pushed fully back into the rack.
• The system must be operated with low pressure rear exhaust installation. (The back pressure
created by rack doors and obstacles should not exceed 5 pascals [0.5mm water gauge].)
Circuit Overloading
The rack should have a safe electrical distribution system. It must provide over current protection for
the unit and must not be overloaded by the total number of units installed in the rack. Consideration
of the units nameplate rating should be used when addressing these concerns.
Reliable Earthing
• The electrical distribution system must provide a reliable earth ground for each unit and the
rack.
• Each power supply in each unit has an earth leakage current of 1.5mA. The design of the
electrical distribution system must take into consideration the total earth leakage current from
all the power supplies in all the units. The rack will require labelling with
HIGH LEAKAGE
CURRENT. Earth connection essential before connecting supply
