2. WIRING
Refer to the interconnection diagram at the back of this manual to connect cables.
Note: For details of JIS (Japan Industrial Standard) cables, see "JIS CABLE
GUIDE" on page AP-4.
Precautions for cable installation
Observe the following guidelines to prevent noise, interference problem.
• The transducer cable carries very weak signals (amplitude less than 0.1 V), which
are easily interfered by noise. The need for a good ground cannot be overempha-
sized. Pass the transducer cable through dedicated conduit. Fill the conduit with vi-
bration absorbing material (sand, etc.) to prevent vibration. The part of the cable ex-
tending from the conduit should be as short as possible. Separate the transducer
cable at least 40 cm from other cables.
• Locate DS-60 cables away from the transmission antenna cable or radio equip-
ment.
• Locate the DS-60 cables away from the power cables mentioned below. Also, sep-
arate cables at least 40 cm when the cables are run parallel with power cables.
• Cable carrying more than a few kilowatts power to fluctuating loads
• Cable carrying switching waves generated by thyristor, etc.
