Installing the uninterruptible power supply (UPS)
It is important to ensure continuous operation of the MS70 independent of varying quality of the vessel's mains supply. The Uninterruptible Power Supply (UPS) must have the capacity to independently maintain power to the MS70 for a minimum of 10 minutes. This ensures that the MS70 can be turned off in a controlled manner in the event of a power failure.
Prerequisites
You must be equipped with a standard set of tools. This tool set must comprise the normal tools for electromechanical tasks, such as different screwdriver types, pliers, spanners and wrenches. Each tool must be provided in various sizes. We recommend that all tools are demagnetized to protect your equipment. Depending on the chosen installation method, additional tools may be required.
Context
Two uninterruptible power supply (UPS) systems are normally required:
•  One UPS is required to power the bridge/control room equipment.
•  One UPS is required to power the sonar room equipment.
The minimum specifications for the uninterruptible power supply are:
•  Input voltage: The input voltage must fit vessel supply voltage
•  Output voltage: 230 VAC, 50 Hz
•  Output power:
–  Processor Unit and display: 1000 W
–  Transceiver Unit: 500 W
–  Power Supply Unit: 800 W (Each)
•  Output form: The output AC voltage must be a sine wave
Note
Uninterruptible power supply units are not included in the standard MS70 delivery. These items must be purchased locally.
Procedure
1 Prepare the location and the necessary tools.
2 Observe the installation requirements.
•  For the relevant environmental requirements and specifications, refer to the relevant documentation provided by the manufacturer.
•  Provide ample space around the unit to allow for inspection, maintenance and parts replacement.
•  Make sure that the space allows the unit door to be fully dismounted for unobstructed access to its internal parts.
•  Verify that the installation does not cause problems with existing cabling, ventilation ducts, piping etc. Check both sides of the bulkhead.
•  Make sure that enough space is made available for maintenance purposes.
•  Make sure that adequate ventilation is available to avoid overheating.
•  Ensure that the installation method allows for the physical vibration, movements and forces normally experienced on a vessel.
3 Verify that the chosen location meets the installation requirements.
4 For a complete installation procedure, refer to the relevant documentation provided by the manufacturer.
