Figure 4.1.3 Finish Treatment of Excitation Cable
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.
4.1.3 Wiring Ports
This instrument is of watertight construction as
stipulated in JIS C0920. It is shipped with a wiring
bracket (waterproof gland or waterproof gland
with union), only in cases where an optional
specification is selected for the wiring port.
When submersible type or option code DHC is
selected, waterproof glands and a 30-meter (or
customer designated) length cable are attached
with resin filled in the terminal box. In this case,
wiring at this terminal box is not necessary and do
not open it.
IMPORTANT
The wiring port is sealed with a cap (not water-
proof). Do not remove the cap from the wiring
port until wiring a cable. If waterproof property is
necessary, please use waterproof glands.
(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. When
wiring, handle the wiring with proper procedures for
necessary protection.
(2) When waterproof property is necessary
(Wiring using waterproof glands)
IMPORTANT
To prevent water or condensation from entering
the terminal box, 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.
Be sure to use the washers and gaskets as shown
in the drawings. Check and see that the cable is
firmly fixed realizing waterproofness.
