Guidelines for Service Personnel

General

The specific warnings and precautions in the sections below are applicable to service personnel.

Requirements for the Installation Site

You should select the installation site carefully. Observe the following rules:

· Protective Earth The protective earth lead of the building installation should comply with the national and local requirements.

· Environmental Condition Keep in mind that electronic equipment requires a dry and clean environment with proper ventilation and cooling facilities. High-humidity conditions can cause corrosion and degradation of electrical components. At all times the installation site should be dry, clean and ventilated. Temperature extremes can cause a variety of problems such as product failure, hardware damage, etc. Ensure that the product is operated in an environment that meets the requirements as stated in the unit’s technical specifications.

Electrical Shock Hazard

Electrical shock can cause personal injury or even death. At any time you must avoid direct contact with dangerous voltages. The protective earth connection is essential to safe operation and must be verified before connecting the power supply. You should know the following safety warnings and guidelines:

· Dangerous Voltages

- Product installation or replacement must be performed by service personnel

only.

- Only service personnel are allowed to remove chassis covers and access any of

the components inside the chassis.

- After service, assemble the unit and ensure it is safe to use before you put it back

in operation.

· Earthing

- Do not violate the earth protection by using an extension cable, power cable or

autotransformer without a protective earth conductor.

- Take care to maintain the protective earthing of the unit during service or repair

and to re-establish it before you put it back in operation.

Fire Hazard

Incorrect use or installation of electrical equipment can cause a risk of fire. Be aware of the following:

· Ventilation Slots and openings in the product housing are provided for ventilation. Do not block these openings and slots as insufficient airflow can be unsafe and cause fire.

· Critical Component Replacement For continued protection against risk of fire; replace critical components only with components of the same type and rating.

· Fuse Replacement Replace fuses only with fuses of the same type and rating.

Precautions

Be aware of the following general precautions and guidelines:

· Wristwatch and Jewelry For your personal safety and to avoid damage of the unit during service and repair, do not wear electrically conducting objects such as wristwatch or jewelry.

ESD

· Lightning Do not work on the product, or connect or disconnect cables during periods of lightning.

· Labels Do not remove any warning labels. Replace damaged or illegible warning labels with new ones.

Electrostatic discharge (ESD) results from the static electricity build up on the human body and other objects. This static discharge can degrade components and cause failures.

Observe the following rules to reduce ESD effects:

· Do not attempt to open a unit without proper precautions against electrostatic discharge such as:

- Use a wrist or ankle strap.

- Use an anti-static tablemat when working inside a product.

· Keep components in their anti-static packaging until you install them.

- Avoid touching electronic components when installing e.g. a module.
