Chapter 8 Working Environment and Maintenance
Suitable working environment and proper maintenance
methods can effectively extend service life of the
equipment. For maintenance please read the contents of
this section carefully.
8.1 System specifications
In public areas ensure that the cables attached to the
system units, including extension cables, are run and laid
out in a neat and tidy manner where they do not interfere
and hinder public walk ways.

Terminating and maintenance of optical fiber
should be carried out by strictly trained technical
staff;

There must be a complete design and
construction drawings, for the convenient and
reliability for future construction and inspection;

During construction, always pay attention not to
press the optical fiber cable by weight or prick by
hard objects; In addition, traction force shall not
exceed the maximal laying tension;

When pulling through the wall or the floor,
protective plastic tube with protective seal should
be used, and fill the tube with flame retardant filler;
A certain amount of plastic pipelines can also be
laid inside the building;
8.2 Environment requirement

Ensure that the area is a dust-free environment.

Ensure adequate ventilation.

Ensure adequate lighting. But be sure that the
lighting does not impede the operator in the
control room and normal system operation.

Do not place objects on the top of units. They
could fall into vents or could cover them and thus
prevent proper cooling of electronic components
inside the units. By falling into a unit, objects could
cause trouble such as fire and electric shock.

To avoid the risk of shock or permanent damage to
the system units, do not expose units to rain or
moisture.

Do not attempt to remove the top cover of the
system main units as you will be exposed to a
shock hazard. The covers should only be removed
by qualified service personnel. If any repair or
maintenance is required, contact the
TAIDEN
service center in your region.

Equipment is only for indoor use. Do not expose it
to sunlight.
WARNING:
Damage to the power cable may cause fire
or a shock hazard!
8.3 Ventilation
Maintain good ventilation: ventilation holes are provided
on top of the main units. Place the units on a hard and
level surface to ensure proper ventilation.
8.4 Cleaning
Do not use alcohol, ammonia or petroleum based liquids
or abrasive cleaners to clean the equipment. Unplug first
and clean with a soft cloth slightly dampened with mild
soap and water solution. Assure yourself that the
relevant unit is dry before operating it.
8.5 Storage
If the units are not to be used for a long period of time,
disconnect the mains supply from all mains supplied
units. Store them in a dust-free dry area with adequate
ventilation.
