Mounting the System into a Rack

Mounting the System into a Rack
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.
●
The system must be operated with low pressure rear exhaust installation
[back pressure created by rack doors and obstacles not to exceed 5
pascals (0.5mm water gauge)].
●
The rack design should take into consideration the maximum operating
ambient temperature for the unit, which is 35°C when fitted with AP-LS
controllers, or 40°C when fitted with JBOD controllers.
●
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. When addressing these
concerns consideration should be given to the electrical power consump-
tion rating shown on the nameplate.
●
The electrical distribution system must provide a reliable earth for each
unit in the rack.
●
The design of the electrical distribution system must take into consider-
ation the total earth leakage current from all the power supplies in all the
units. The rack may require labelling with “HIGH LEAKAGE CURRENT.
Earth connection essential before connecting supply”.
●
The rack when configured with the units must meet the safety require-
ments of UL 60950-1 and IEC 60950-1.
Rack Toppling Over
Racks may toppling over due to a massive over-
weight in the upper part.
Do not slide more than one enclosure out of
the rack at a time. When loading a rack with
enclosures, fill from the bottom up; empty
from the top down. Close all enclosures
before loading.
