4. WIRING<br />
NOTE<br />
• For excitation cables, always use a crimp<br />
terminal with an insulation cover.<br />
• Use crimp tools from the manufacturer of the<br />
crimp terminal you want to use to connect the<br />
crimp terminal and cable.<br />
• Use crimp tools that are appropriate for the<br />
diameter of the cable to be connected.<br />
4.2.3 Wiring Ports<br />
This instrument is of watertight construction as<br />
stipulated in JIS C0920-1982. (Tests to prove protection<br />
against ingress of water and degrees of protection<br />
against ingress of solid objects for electrical equipment.)<br />
It is shipped with a wiring bracket (waterproof<br />
gland or waterproof gland with union) or a plastic<br />
gland attached, only in cases where an optional<br />
specification is selected for the wiring port.<br />
In case of the explosion proof type, refer to chapter 8.<br />
(1) When there are no particular optional<br />
specifications<br />
The wiring port is sealed with a cap (not water-proof)<br />
that must be removed before wiring. At this time,<br />
handle the wiring port in accordance with the JIS<br />
C0920-1982 mentioned above.<br />
(2) Wiring using waterproof glands<br />
IMPORTANT<br />
To prevent water or condensation from entering<br />
the converter housing, waterproof glands are<br />
recommended. Do not over-tighten the glands or<br />
damage to the cables may result. Tightness of<br />
the gland can be checked by confirming that the<br />
cable is held firmly in place.<br />
