Environmental requirements
The EM 2040 MKII topside units must be installed in a dry and dust-free environment.
The units are not fully protected against humidity, dust or water.
It is important that the sonar room is kept dry. The EM 2040 MKII topside units must not
be exposed to excessive temperatures, dust, moisture or humidity. Such conditions can
cause corrosive attacks and subsequent failures to the electronic circuitry. Visit the sonar
room at regular intervals to check temperature and humidity, and take the necessary
actions if the environmental conditions are poor.
Avoid running large power cables trough the sonar room.
Observe the environmental specifications related to the EM 2040 MKII units.
Size and access requirements
A well designed sonar room with a well fitted size and easy access reduces the risk of
corrosion, and simplifies maintenance. This increases system reliability.
The sonar room must be large enough to house all the system units. The room must
provide enough space to allow efficient maintenance. You must be able to keep all the
cabinet doors fully open without undue restriction to your movements.
1 The room must not be used for any other heavy machinery.
2 The room must not be unnecessarily obstructed by girders, pipes etc, which may
cause installation problems or impede maintenance.
3 The sonar room must be accessible under all conditions at sea or at a berth.
4 All doors or hatches must be designed so that the tools and equipment can be
removed without being disassembled.
