EM 122
Location
The EM 122 Preamplifier Unit is normally installed in the vessel’s “sonar room” close to
the transducer arrays. This room must be dry and free from excessive dust and vibration.
Maximum humidity of 80% is recommended. Good ventilation for the equipment
cooling must be provided.
Kongsberg Maritime recommends that this room is chosen close enough to the RX
transducer arrays so that you do not need to extend the transducer cables. These have a
standard length of 25 meter.
The cabinet must be mounted on the bulkhead. Ensure that sufficient space is provided
around the unit to allow the unit’s doors to open fully. Space must be provided to
allow the power and interface cables to be installed, and to allow the cabinet to move
on its shock absorbers.
Note
Restrictions exist concerning the Sonar Room EMC screen.
General information
The Preamplifier Unit cabinet is fitted with hinges to allow the front to be opened, this
gives access to both the front and rear sides of all the circuit boards.
The unit is designed to be mounted on a support frame. This frame is mounted on the
bulkhead with four shock absorbers, two mounted on top of the frame and two at the
bottom.
