3. PRIOR CONFIRMATION
3.1. Confirmation Items
1) The set of “accessories for installation” (Refer to section 2.4) must be installed properly on
Antenna Unit (radome).
2) Power cable (AC100V-240V) must be routed safely.
3) Power cable gauge should be selected depending on its length.
4) Frequency of AC power source must be 50Hz or 60Hz sine wave and single-phase current.
5) All engineers must wear safety appliances including helmet and safety shoes during an
installation of Antenna Unit. It is dangerous that antenna could hit an individual by turning.
6) Secure a service space of 1 m or more around the radome. In addition, strong reflections can
damage the receiver if there are obstacles nearby.
7) Set the sector blank to the obstacle direction nearby. When transmitting in the direction of the
obstacle, some pseudo echoes will be indicated due to reflections, therefore set the sector
blank until the pseudo echo disappear.
Cautions:
1> DO NOT look at the antenna closer than noted below while radar is in operation. This
energy can be extremely damaging to the human body, especially the eyes. Furthermore
DO NOT points the antenna at any individuals closer than noted below while transmitting.
2> As shown in Installation manual preface warnings (Table on page i, Radio Frequency
Radiation Hazard), the danger distance of transmit radio wave is set to 10W/m

value for
safe standard, therefore do not go closer to the radar.
3.2. Power Equipment
1) This equipment requires 1KVA x1 power line with grounded outlet (3 cores type).
2)
The AC power cable attached to the DPU power supply is bundled with items conforming to
the PSE standard (Japan) and UL standard (US). Please prepare the power cable according
to the safety standards of the area to be equipped on the customer side.
3) Crimp terminals are necessary to be attached to the power line to connect with terminal block
in SPU.
4) Do not bend, tightly bend, place objects on, bundle, or forcibly pull the power cable. Please
handle with care.
5) If the outlet is dusty or wet, be sure to clean it before use.
6) Do not handle with wet hands.
