Safety and precautions

General

All electrically powered equipment can be dangerous. At BARCO we have taken

great care to ensure safety during the design and production of our equipment. Incor-

rect installation, handling, or interference can, however, impair the safety.

This product complies with the requirements of the directive 73/23/EEC.

ESD (electrostatic

discharge)

Electronic products contain electrostatic sensitive components. Observe the follow-

ing rule:

• Do not attempt to open a unit without proper precautions against electrostatic dis-

charge, i.e. use a wrist strap and conductive work-bench surface.

Reason:

The unit may fail or be degraded.

Installation

This product requires protective earthing. With 110/230 V AC this is normally

obtained by the use of the supplied 3-wire power cable.

During installation, observe the following rules:

• Establish a separate safety earth connection if the power installation of the build-

ing does not have a direct connection to earth.

• Ensure that the unit has the correct line voltage rating.

• Do not use an extension cord (power cable) without a protective conductor.

•

Do not remove the covers

Servicing

Only trained service personnel should attempt to dismantle and repair the unit.

During service observe the following rules:

• Before removing any covers, switch off the power and remove the line cable

from the unit.

Observe:

Capacitors inside the unit may hold dangerous charges for a consider-

able time after the unit has been switched off.

• If it is necessary to replace components in the line connected circuits, use only

new parts of the correct and specified type.

• Take care to maintain or re-establish the protective earthing of the unit during

service or repair.

• Do not remove any warning labels. Replace damaged or illegible warning labels

with new ones.
