(POS MV V4-1) Connect an electrical supply of nominal voltage
24 Vdc at 2.5 A (voltage range - 20 Vdc to 34 Vdc) to the 3-pin
power inlet connector on the PCS.
c) GNSS Antenna Positioning:
Ensure there is a horizontal separation distance of between 1.0
and 5.0 m (~3 ¼ and ~16 ½ ft) between the primary and the
secondary GNSS antennas.
Mount the antennas as high as possible on the vessel.
Do not mount the antennas close to MF, HF, VHF or UHF
transmitters or antennas. Do not mount the GNSS antennas
within 0.5 m (~±19 ¾ in) of radar or satellite communications
equipment.
Avoid mounting the antennas near large flat surfaces.
Avoid mounting the antennas in a location where they may move,
twist or vibrate significantly relative to the vessel or the IMU.
2. Offset Measurements
Measure the lever arm distances and mounting angles, as
instructed in
Lever Arm Distances on page 2-41 and Mounting
Angles on page
2-47. Be as careful and accurate as possible.
Measure the GNSS antenna separation distance, as instructed in
Antenna Separation on page 2-47. Be as careful and accurate as
possible.
3. Power Supply
The application of incorrect electrical power to the PCS may
result in damage to POS MV system.
(POS MV V4) Arrange a clean, stable electrical supply at a
nominal voltage
110 Vac at 1.0 A; 240 Vac at 0.25 A, 47 to 63 Hz
(voltage range -
90 Vac to 264 Vac) for the PCS. If possible,
supply electrical power to the PCS from an uninterruptible power
supply.
