Installation

Introduction

The panel computer should be mounted into a milled panel cut out. Please review Technical Drawings in this manual.

General Installation and mounting issues

1. Most of our products are intended for various methods of installation or mounting (panel mounting, bracket

mounting, ceiling/wall mounting etc.); for details, please see the relevant mechanical drawings.

2. Adequate ventilation is a necessary prerequisite for the life of the product. The air inlet and outlet openings must

definitely be kept clear; coverings which restrict ventilation are not permissible.

3. Do not install the unit in a horizontal position (laying down), as this will cause heat to build up inside the display

which will damage the LCD Panel. To prevent this problem we recommend installing the unit in a vertical position

(±30 degrees) to improve the airflow through the unit.

4. Exposure to direct sunlight can cause a considerable increase in the temperature of the unit, and might under

certain circumstances lead to overtemperature. This point should already be taken into consideration when the

bridge equipment is being planned (sun shades, distance from the windows, ventilation, etc.)

5. Space necessary for ventilation, for cable inlets, for the operating procedures and for maintenance, must be

provided.

6. To further improve the cooling of the unit we recommend installing Cooling Fans underneath blowing upwards into

the unit air inlet. This may be required in high temperature applications and also when there is reason to expect

temperature problems due to non-optimal way of mounting(Ref.2-5).

7. If the push buttons of the product are not illuminated, an external, dimmable illumination (IEC 60945 Ed. 4, 4.2.2.3,

e.g. Goose neck light) is required for navigational use. The illumination shall be dazzle-free and adjustable to

extinction.

8. Information about necessary pull-relievers for cables is given in the installation drawings. Attention must be paid to

this information so that cable breaks will not occur, e.g. during service work.

9. Expose to heavy vibration and acoustic noise might under certain circumstances affect functionality and expected

lifetime. This must be considered during system assembly and installation. Mounting position must carefully be

selected to avoid any exposure of amplified vibration.

Ergonomics

1. Adjust the unit height so that the top of the screen is at or below eye level. Your eyes should look slightly

downwards when viewing the middle of the screen.

2. Adjust screen inclination to remain gaze angle to the centre of the screen approximately perpendicular to the line

of gaze.

3. When products are to be operated both from a sitting position and from a standing position, a screen inclination of

about 30° to 40° (from a vertical plane) has turned out to be favourable.

4. The brightness of displays is limited. Sunlight passing directly through the bridge windows - or its reflection - which

falls upon the screen workplaces must be reduced by suitable means (negatively inclined window surfaces,

Venetian blinds, distance from the windows, dark colouring of the deckhead).
