3-2
3.1.2 Checking
procedures
3.1.2.1
Checking the installation of the equipment
•
Is the equipment installed in the correct location?
•
Check if there is enough space for removing the side and top plates of the NTD-2150, and that
there is nothing obstructing the cooling fan.
•
Is any equipment installed upside down?
•
Are all the screws tight?
•
Is the equipment's name plate installed so it is easily visible?
•
Is the handset cradle installed in an easy-to-use location?
•
Is the AC/DC power supply (NBD-2150) in the path of the exhaust?
•
Is the battery charger (NBB-724) in the path of the exhaust?
•
Is the equipment's ground properly connected?
•
Have dust and other debris from installation work been cleaned up?
3.1.2.2 Checking
the
wiring
•
Are the cable types, connections, and wiring to the terminal blocks done correctly?
•
Is the cable properly fixed to the terminal block so it does not disconnect when pulled?
•
Has too much insulation been stripped from the wires so too much bare wire is exposed near the
terminal block?
•
Is the cable fixed to the cable clamp?
•
Are the 3 antenna cables in the NTD-2150 securely inserted into the board connectors?
•
Are the flat cable (W4) and power cable (W5) in the NTD-2150 securely inserted into the board
connectors?
•
Is the coaxial cable between the transceiver's Tx power (TX ANT) and the antenna tuner OK?
* Check the cable itself for shorts between the central conductor and the shielding, if the central
conductor is broken, etc.
•
Is any cable caught between the upper part and bottom part of the NTD-2150?
3.1.2.3
Checking the antenna installation
* Check the following for all of the antennas (TX, RX, WKR) used.
•
Is the antenna installed in a suitable location?
•
Is the antenna fixed?
•
Is the connector of the coaxial cable securely connected?
•
Has the connector been properly waterproofed?
3.1.2.4
Checking the voltage of power source
•
Check the AC power voltage at the AC IN terminal of the AC/DC power supply (NBD-2150) with
a tester.
Rating: 90 to 132 VAC or 180 to 264 VAC
•
Check the DC power voltage at the 24 VDC IN terminal of the AC/DC power supply (NBD-2150)
with a tester.
Rating: 21.6 to 31.2 VDC
•
Check if the DC power voltage is within the ratings at the NTD-2150 24 V input terminal with a
tester.
Rating: 21.6 to 31.2 VDC
•
Check if the DC power voltage during transmission is within the ratings at the NTD-2150 24 V
input terminal with a tester.
•
Check if the AC/DC power supply (NBD-2150) automatically switch to DC input when AC input
