Installer Guidelines for Telecom Equipment.

Installer Guidelines for Telecom Equipment.

Observe the Following General Safety Guidelines-

• The equipment is intended for installation in restricted access areas. A restricted access area is an area where only service personnel are granted access by means of a  special tool,key or other means of security and is under supervision of the authority responsible for the location.
• Only trained personnel are allowed to perform the installation,service and maintenance activities.
• Irrelevant or unauthorized personnel should not be permitted access to TE installation and service area.
• Keep the equipments are dust-free and clear of obstructions before ,during and after installation.
• Keep tools and equipment away from walking path.
• Do not wear loose cloths or any other items that might be caught in the equipment during installation and service and secure long hair.
• All the rack doors should be installed and keep closed.
• Never attempt to drill the rack or equipment by yourself or wiring and cables in rack may  be damaged a d Anti-electromagnetic radiation(EMC) function may be also destroyed.

Standards for Telecommunications Equipment Lifting

Numbers of people needed to lift the equipment according to its weight.

i. One people < 18 Kg.

ii. Two people = 18 to 32 Kg.

iii. Three people = 32 to 55 Kg.

iv. Machine required  > 55 Kg.

Proper Airflow:-

• Check the recommended ambient temperature for the equipment on normal operation.take care to allow sufficient air circulation or space between units.
• Ensure that rack has adequate ventilation.
• Ensure that cables from alternative instrumentality don't impede the flow.
• Radio frequency interference can occur due to poor wiring.

ESD safety (Electrostatic Discharge Damage):

Electrostatic Discharge Damage may result in immediate failure,or it may manifest itself as a latent failure,affecting the reliability of the equipment.

• To ensure safety check the resistance value of the ESD-protection wrist strap and ankle straps periodically the measurement should be between from 1 to 10 megohm (M-ohm)

DC Potential Difference and Grounding:

• Ground the equipment properly according to the power standard of the country in which it is installed.
• In order to avoid equipment damaged by lightning  grounding work should be well finished.
• When the equipments installed in two fields need to be connected to each other,potential difference exists between earth wires from different field. Which may result in equipment damaged or performance deterioration.

Laser and Fiber Safety:-

• The laser beam can hurt your eyes When optical fiber installation,maintenance or other operations are going on do not make your naked eyes close to the fiber outlet or look directly at the fiber outlet.
• Because an un-terminated optical connector may emit laser radiation the engineer must not view this beam with an optical instrument.
• Only special cleaning tool and material are allowed to clean the fiber connectors.
• Optical connectors can be damaged if their protective covers or dust caps are not installed when the connectors are not in use.
