In case of power cable, Green/Yellow covered conductor
shall be used only for connection to PROTECTIVE
CONDUCTOR TERMINALS. Conform to IEC227,
IEC245 or equivalent national authorization.
NOTE
• For power cables, always use a crimp terminal

• 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 for Integral Flowmeter
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
specicationisselectedforthewiringport.
In case of the explosion proof type, refer to Chapter 10.
IMPORTANT
The wiring port is sealed with a cap (not waterproof).
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 depending on
thespecication.
If it is necessary, contact YOKOGAWA.
(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. 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
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.
