to install the POS MV. By taking this precaution, you will become more
familiar with the requirements of the system and will be less likely to
encounter unexpected problems during this important operation.
Note: Before installing the POS MV, make certain that adequate mounting
provisions exist for all components of the system.
Power Requirements
Applanix strongly recommends that you arrange to supply electrical power to
the POS MV from an Uninterrupted Power Supply (UPS). This is for two
reasons:
• Usually, the electrical supply on board the vessel will be noisy.
Although the POS MV includes power supply conditioning circuitry, it
is a sensible precaution to make certain the power supply is ‘clean’
before it enters the system.
• The electrical supply on board the vessel may be unreliable and may
drop out or fall to an unacceptable level unexpectedly.
A suitable UPS will ‘clean’ the electrical supply before it enters the PCS and
will continue to supply power for a short period if the electrical supply fails for
any reason. The UPS should be able to supply the total power requirements
of POS MV.
