SAFETY INSTRUCTIONS
The operator and installer must read the appropriate safety instructions before attempting to
install or operate the equipment.
Indicates a hazardous situation which, if not avoided, will result in
death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
can result in minor or moderate injury.
Warning, Caution Prohibitive Action Mandatory Action
DANGER
Radio Frequency Radiation Hazard
The radar antenna emits the electromagnetic radio frequency (RF) energy which can be harmful,
particularly to your eyes. Do not look at the Antenna Unit from a close distance while the radar is
in operation, or expose yourself to the transmitting antenna at a close distance.
The distances at which RF radiation levels of 10 W/m2exist are shown in the table below.
DO NOT approach closer than 9.1 m (Safety standard is 10 W/m2) when radar is transmitting.
Note:
This value is applied when radar is installed in a public space. Value is defined as on human
body surface over a 6-minute period with the flux density averaged from the measurement.
Moreover, this measured value is measured by pointing the center of the antenna towards a
human. However this is the worst value, definition required by actual regulation is written here
as on safe side.
Distance from Antenna
9.1 m
Power flux density
10 W/m 2
WARNING
Do not open the radome.
Electrical shock can occur. Only qualified personnel should work inside the equipment.
Turn off the breaker in the SPU if opening the radome is required.
Wear a hard hat and safety belt when mounting the Antenna Unit.
Serious injury or death can result from falls or dropped items while installing or servicing the
radar components.
Do not use any other power except 100 to 240 VAC.
Connection of an incorrect power supply can cause fire or damage the equipment.
Turn off the power immediately if water leaks into the equipment or
smoke or fire is coming from the equipment.
Failure to turn off the equipment can cause fire or electrical shock.
Do not operate the equipment with wet hands.
Electrical shock can occur.

RADIATION WARNING LABEL
Radiation warning labels are attached to the equipment. Do not remove any label.
If a label is missing or damaged, contact us for the replacement.
POWER SUPPLY LABEL
100-240 VAC
SINGLE PHASE, 50/60 Hz
POWER CONSUMPTION: MAX. 650W *1
RATED AMPERE: 6.5-4.3A (100-150VAC)
3.2-2.7A (200-240VAC)
Note: Total maximum power consumption of ATU (350W) and SPU (300W).
Do not disassemble or modify the equipment.
Fire or electrical shock can occur.
Use only the specified power cord/cable.
Fire or damage to the equipment can result if a different cable is used.
Use the power supply grounded certainly.
Electrical shock or defect of operation can occur.
When a thunderbolt is expected, do not approach a system or do
not touch a hand.
There is a possibility of receiving an electric shock.
A worker's safety is guaranteed however the radar’s internal protection devices only
protect against indirect lightning and surges to the radar components. In case of a direct
lightning strike these protection devices may not protect radar or surrounding personnel.
Install the radar lower than 2,000m altitude.
When the radar is installed above 1,000m, the life time will be shorter due to deterioration
of oil seal and the grease leakage by low pressure, especially for ball bearings in the
motors, fans, and spindles. The radar must be installed lower than 2,000m altitude.
Attach securely protective earth to the unit.
The protective earth (grounding) is required to the AC power supply to prevent electrical
shock.
CAUTION
Do not put liquid-filled containers on the top of the equipment.
Fire or electrical shock can occur if a liquid spills into the equipment.
Establish best possible surrounding space for apparatus.
This helps eliminate performance degradation and failure.
Do not impact the LCD glass.
Serious injury may occur due to broken glass.

WR2120 Restrictions
There are restrictions frequency band;
CH1: 9422.5MHz, CH2: 9427.5MHz, CH3: 9432.5MHz, CH4: 9437.5MHz in the following countries:
Switzerland, Lithuania, and Slovakia.
Shipment of Weather Radar
Whole weather radar equipment (ATU, SPU, DPU, and others) will be shipped by air or sea from
Japan to overseas. A person who is in charge of installing radar has to keep a packing list in safe
because it is written serial number of each unit (ATU, SPU, and DPU) that makes one set.
It has to more careful when arrived more than 2 sets of radars because it only works with
combinations of serial number listed in the packing list. Therefore, if shuffled with other radar unit, it
will not work properly.
