NVIRONMENTAL REQUIREMENTS
3 ENVIRONMENTAL REQUIREMENTS
Read through each device installation documentation, and from there, conclude that all
of the equipment can be installed.
For MX-ONE, an analogue trunk line generates a touch or leakage current which if
there are several analogue trunk lines installed, calls for the installation to be in a
“Restricted Access Location". The 3U and 7U chassis are marked with a warning text
"High voltage current..." to reflect this.
Note: Values below are relevant for MX-ONE products. For other products see
suppliers Technical Specification.
The exchange room must meet the following requirements:
• The air shall not contain any dust, smoke, gases or acid fumes
• Temperature +5 to +40
o
C (+41 to +104
o
F)
• Relative air humidity 20-80%
• The relationship between temperature and air humidity shall not cause conden-
sation
• The equipment must not be exposed to direct sunlight
• Make sure that the floor withstands the mass of the PBX
• For concrete floor, the distributed load is the total mass of equipment in the room
divided by the area of the room
• For wooden floor, extra caution must be taken concerning the spot load of the
cabinets
• The floor should be covered by an earthed anti-static carpet in order to reduce
the risk of the exchange being exposed to interference caused by static elec-
tricity
If the batteries are to be installed in the exchange room, they must be of a type which
does not produce gases or acid fumes.
If the batteries are to be installed in a room outside the exchange room, the environ-
mental conditions must comply with the battery suppliers instructions.
The PBX operators room should be of standard office design, but the floor as in the
exchange room should be covered by an anti-static carpet.
