4.1 Field Wiring
(1)Cables for eld wiring
The following cables should be used unless otherwise specied.
Shielded chloroprene cabtyre cables (kind 2, JIS C 3327, shielded) or shielded vinyl cabtyre
cables (JIS C 3312, shielded) with a conductor area 1.25mm
2
.
3-conductor cables may be used to suit your specic application. Shielded end should be grounded
a
t the ground terminal of the receiving instrument.
(2)Transmission length
With transmission cables conforming to JIS C 3327 or C 3312 conductor area 1.25mm
2
, the
maximum transmission length is typically one kilometer.
NOTE:
If
it exceeds one kilometer, consult factory.
(3)Prevention of inductive interference
T
o minimize the possibility of stray current pickup, route the eld wiring sufciently away from other
power cables and power circuits.
CAUTION: Verify the validity of flowmeter (pulse generator) to receiving instrument
combination by their product No., instrument No., etc. before making wiring
connections.
NOTE : Also see the topic "WIRING" in the instruction
manual of the receiving instrument used.
