NOTE
• For excitation cables, always use a crimp
terminal with an insulation cover.
• Use crimp tools from the manufacturer of the
crimp terminal you want to use to connect the
crimp terminal and cable.
• Use crimp tools that are appropriate for the
diameter of the cable to be connected.

Wiring Ports
This instrument is of watertight construction as
stipulated in JIS C 0920. It is shipped with a wiring
bracket (waterproof gland or waterproof gland with
union) or a plastic gland attached, only in cases where
an optional specification is selected for the wiring port.
In case of the explosion proof type, refer to Chapter 8.
IMPORTANT
The wiring port is sealed with a cap (not water-
proof). Do not remove the cap from the unused
wiring port. If waterproof property is necessary
apply a blanking plug to the unused wiring port.
The blanking plug may not be attached depend-
ing on the specification. If it is necessary,
contact YOKOGAWA.
(1) When waterproof property is unnecessary
(When there are no particular optional
specifications)
The wiring port is sealed with a cap (not water-proof)
that must be removed before wiring. At this time,
handle the wiring port in accordance with the JIS
C 0920 mentioned above. Do not remove the cap from
the unused wiring port.
(2) When waterproof property is necessary
(Wiring using waterproof glands)
IMPORTANT
To prevent water or condensation from entering
the converter housing, waterproof glands are
recommended. Do not over-tighten the glands or
damage to the cables may result. Tightness of
the gland can be checked by confirming that the
cable is held firmly in place.
For working on the electric wire tubes or the flexible
tubes (G1/2), remove the waterproof gland and attach
them directly to the wiring port.
