European Regulations
This equipment complies with European Regulations EN 
55022 Class A: Limits and Methods of Measurement of Radio 
Disturbance Characteristics of Information Technology 
Equipments and EN50082-1: Generic Immunity.
USA Federal Communications Commission (FCC)
This equipment has been tested and found to comply with the 
limits for a class A digital device, pursuant to part 15 of the 
FCC rules.
Safety
1.1.
All plug-in modules and blank plates are part of the fire 
enclosure and must only be removed when a replacement 
can be immediately added. The system must not be run 
without all modules in place.
Permanently unplug the unit if you think that it has become 
damaged in any way and before you move it.
• The enclosure can weigh up to 32kg (70.4lb). Do not try to 
lift it by yourself.
• Do not lift a populated enclosure by the module handles or 
those on the front of the enclosure, they are not designed to 
support the weight of the populated enclosure.
• In order to comply with applicable safety, emission and 
thermal requirements no covers should be removed and all 
bays must be fitted with plug-in modules.
• The enclosure must only be operated from a power supply 
input voltage range of 100-120VAC or 200-240VAC.
• The power supply is used as the main disconnect device. 
Ensure that the socket outlets are located near the equipment 
and are easily accessible.
• The equipment is designed to be operated with two working 
power supply modules.
• To prevent overheating do not operate the enclosure with 
one power supply removed for more than 30 minutes.
• Disconnect all supply power for complete isolation.
• The power connection should always be disconnected prior 
to removal of the Power Supply module from the enclosure.
• A safe electrical earth connection must be provided to the 
power cords. Check the grounding of the enclosure before 
applying power.
• Provide a suitable power source with electrical overload 
protection to meet the requirements laid down in the technical 
specification.
Rack System Precautions
1.2.
The following safety requirements must be considered when 
the unit is mounted in a rack.
• The rack design must incorporate stabilizing features 
suitable to prevent the rack from tipping or being pushed 
over during installation or in normal use.
• To avoid the danger of the rack tipping over, do not slide 
more than one enclosure out at once.
• When loading a rack with the units, fill the rack from the 
bottom up and empty from the top down.
• The rack design should take into consideration the 
maximum operating ambient temperature for the unit, 
which is 40°C.
• 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 must 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 electrical power consumption 
rating shown on the nameplate should be used when 
addressing these concerns.
• The electrical distribution system must provide a reliable 
earth for each unit in the rack.
• Each power supply in each unit has an earth leakage 
current of 1.5mA max at 60Hz, 264VAC per PSU. 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 may 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 60950-1 and IEC 60950-1.
