5. Installation
When installing the equipment, securely connect the earth lead to the earth
terminal.
Failure to connect the earth may result in electric shock in the event of a fault or
power leak developing.
Do not install or operate the equipment where subject to temperatures 55°C or
higher or –15°C or lower.
Failure to observe this caution may result in fire or damage.
Do not install the equipment on unstable or unlevel surfaces. Failure to
observe this condition may result in the equipment falling or toppling over,
resulting in injury.
Take care when laying the transducer cable, power cable, and earth lead as
positioning has an affect on electromagnetic interference. There is a risk of
interfering with other equipment or the echo-sounder being interfered with by
the other equipment.
After installing the echo-sounder, turn on the power to all other equipment to
check for interference with or from all the equipment. Interference may cause
malfunctions.
