General Installation Recommendations
Installation
General mounting instructions
1. The useful life of the components of all Electronics Units generally decreases with increasing ambient temperature;
it is therefore advisable to install such units in air-conditioned rooms. If there are no such facilities these rooms
must at least be dry, adequately ventilated and kept at a suitable temperature in order to prevent the formation of
condensation inside the display unit.
2. With most Electronic Units, cooling takes place via the surface of the casing. The cooling must not be impaired by
partial covering of the unit or by installation of the unit in a confined cabinet.
3. In the area of the wheel house, the distance of each electronics unit from the magnetic standard compass or the
magnetic steering compass must not be less than the permitted magnetic protection distance. This distance is
measured from the centre of the magnetic system of the compass to the nearest point on the corresponding unit
concerned.
4. Units which are to be used on the bridge wing must be installed inside the “wing control console” protected against
the weather. In order to avoid misting of the viewing screen, a 25 ... 50 W console-heating (power depending on the
volume) is recommended.
5. When selecting the site of a display unit, the maximum cable lengths have to be considered.
6. When a product is being installed, the surface base or bulkhead must be checked to ensure that it is flat in order to
avoid twisting of the unit when the fixing screws are tightened, because such twisting would impair mechanical
functions. Any unevenness should be compensated for by means of spacing-washers.
7. Products with AC input must be grounded to protective Earth (Safety Ground) when necessary via the bolt (usually
on terminal plate) available on the product.
Products with DC input must be grounded to protective Earth (Safety Ground) via the bolt (usually on terminal
plate) available on the product.
A shorter and thicker cable gives better grounding. A 6mm² is recommended, but a 4mm² or even 2.5mm² can be
used for this purpose.
8. Transportation damage, even if apparently insignificant at first glance, must immediately be examined and be
reported to the freight carrier. The moment of setting-to-work of the equipment is too late, not only for reporting the
damage but also for the supply of replacements.
9. The classification is only valid for approved mounting brackets provided by Hatteland Technology. The unit shall be
mounted stand-alone without any devices or loose parts placed at or nearby the unit. Any other type of mounting
might require test and re-classification.
10. Additional rules may apply to certain procedures where the symbols and are present. For more information,
review “IEC62368 policy for Hatteland Technology product” section later in this manual.
Brightness knob precaution
Applies for models with potmeter knob. Please be aware of the risk of breaking or bending the brightness knob. The
brightness knob should be free of any obstruction.
