Air traffic
Danger of interference caused by RF energy.
The operation of wireless appliances in an aircraft is forbidden to prevent interference with
communications systems. Failure to observe these instructions may lead to the suspension or denial of
cellular services to the offender, legal action, or both.
•
Switch off WS unit before boarding an aircraft.
•
Make sure it cannot be switched on inadvertently.
Explosives
Danger of explosion.
The device does not comply with Directive 94/9/EC and must therefore not be used in potentially
explosive areas.
•
Observe the applicable regulations and precautions when you are near explosive areas (i.e. petrol
stations, fuel depots, chemical plants or where blasting operations are in progress).
•
Do not mount the antenna in the close environment of fuel tanks, vessels with explosives and
insufficiently shielded electronic devices.
Antennas
Danger due to absorption of RF energy.
Mobile communication devices may pose a health risk when operated in the close proximity of persons.
•
Install the antenna(s) used for the WS unit devices to provide a separation distance of at least 20 cm /
8 inches from all persons.
•
Do not operate them in conjunction or co-locate them with any other antenna or transmitter.
Electronic equipment
Danger of interference caused by RF energy
WS unit receives and transmits radio frequency energy while switched on. Interference may occur if it is
used close to TV sets, radios, computers or inadequately shielded equipment.
Follow any special regulations and always switch off the WS unit wherever forbidden, or when you
suspect that it may cause interference or danger.
Avoidance of property damage
W
Warning
Before any installation of the Control system can take place, make sure the ignition lock is turned off and
the battery is disconnected. Disconnect the device externally before handling it. Also disconnect any
independently supplied output load circuits.
Connecting of Supply Voltage
The supply voltage, should be within the operating range. Connect the supply voltage to power supply.
Protect the module by using a fuse. Requisite fuse level should be 1 A, fast (F). To avoid damage to the
device, connect/disconnect the main connector only if the power supply to the device is switched off.
Connect the WS to the same power and ground as the Control system. The power supply must be
common to both the WS and the Control unit to ensure trouble free communication. Most importantly,
the ground connection, must be the same.
Do not use the chassis as the negative terminal.
