Installation
The CSP-N Unit will normally be supplied from the factory in a ‘Hardigg’ transit case. As is the case
with all electronic equipment, care should be exercised in handling. For maximum airflow in high
ambient temperatures it is recommended that the anti-vibration housing rear panel be removed.
The CSP-N should be positioned on its base in a dry ventilated area. Airflow for cooling is from
back-to-front of the unit; there must be at least 50-60mm clear room from the rear panel to any
obstruction. If the unit is to be operated in very warm ambient temperature (25°C or above), for
optimum performance an air conditioned environment is strongly advised. If the unit overheats, it
will switch OFF for a few minutes until it is cool.
Although the unit produces minimal interference, and carries a CE mark, it is often good practice to
put the CSP-N away from the navigation and survey equipment and somewhere where cabling to
the sound source can be run conveniently and safely. It is this cabling which is the most common
source of electrical interference.
EARTHING - FURTHER REMINDER
THIS UNIT MUST BE EARTHED / GROUNDED BEFORE ANY POWER IS APPLIED. FAILURE
TO DO SO MAY REPRESENT A SEVERE HAZARD TO BOTH EQUIPMENT AND
PERSONNEL.
The front of the CSP-N must be grounded to the ship’s ground system. This is achieved by
attaching a short length of thick wire or earth braid from the CSP-N front panel earth stud, to an
appropriate earthing point on the vessel. If a suitable earth cannot be found, the CSP-N earth stud
should be connected directly to the water using an adequate length of heavy wire, with the
insulation removed from the submerged end in the water. A weight will also be necessary to keep
the wire submerged when the vessel is underway.
Output Cable Connection
ENSURE POWER TO UNIT IS TURNED OFF BEFORE ANY CONNECTIONS ARE MADE.
Connect the high voltage cable to the CSP-N front panel using the high voltage connector. The HV
connector has 2 small sensing pins which will deactivate the high voltage if mains power is applied
without the connector in place. Ensure the HV connector is fully mated to the unit. The two larger
sockets should never be at a high potential but it makes sense never to attempt to touch these.
If you have our HV junction box, the two conductors of the acoustic source - boomer plate or
sparker should be connected to this before connecting to the CSP-N. The terminal wing nuts
should be tightened onto clean copper or tinned copper terminals. A good connection is necessary
as high currents pass through these terminals. Ensure that the +ve or red terminal is connected to
the + mark inside the HV Junction box. The black or –ve terminal should be connected to the –
mark inside the HV junction Box. Ensure that the microswitch ‘clicks’ when the top cover is
secured. The HV Junction Box can be bulkhead mounted before the cover is secured.
