Rack System Precautions
The following safety requirements must be considered when the unit is mounted in a rack.
• 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].)
• The rack design should take into consideration the maximum operating ambient temperature for the
unit is 35°C.
• 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.
• 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
.”
• The rack when configured with the units must meet the safety requirements of UL 60950 and IEC
60950.
