Precautions for Installation
1) Supply voltage
JAX-9B operates within the following voltage range shown below.
•
DC power supply: +10Vdc to +42Vdc
(Standard voltage: +12Vdc, +24Vdc, +32Vdc -10% to +30%)
•
AC power supply: Option (Rectifier unit NBA-5143 is required.)
NOTE
•
When not using AC power supply (option), connect cables after confirming the
voltage between FG and the minus terminal of DC power supply is 0V.
2) Selection of FUSE
The capacity of a fuse available to JAX-9B varies depending on the supply voltage. JAX-9B is
equipped with 5A fuse at the factory. Select a proper fuse (among replacement fuses) according to
the supply voltage and set it in the fuse holder.
The fuse holders are next to the power switch on the rear of JAX-9B.
•
+12Vdc power supply: Use an 8A fuse.
•
+24Vdc power supply: Use a 5A fuse.
•
+32Vdc power supply: Use a 5A fuse.

When using existing equipment
When connecting existing equipment that has already been in use inboard such as antennas and
external receivers, etc., connect them to JAX-9B after confirming the result of single-equipment
operation is normal. (Whether or not it is damaged and it starts up with power supply, and insulation
check, etc.)
