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

specication 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 lled 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

specications)

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 conrming that the

cable is held rmly in place.

For working on the electric wire tubes or the exible

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

rmly xed realizing waterproofness.
