Rack System Precautions
The following safety requirements must be considered when the unit is mounted in a rack.
• The rack 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.
• The rack should comply with the airflow requirements detailed in this user guide.
• The rack design should take into consideration the maximum operating ambient temperature for the
unit, which is 40°C when dual cooling modules are fitted.
• The rack should have a safe electrical distribution system. it must provide overcurrent 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 for each unit and the rack.
• Each power supply in each unit has an earth leakage current of 1.7mA. 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 UL60950 and IEC
60950.
