NOTE
• For excitation and power cables, always use a

• Use crimp tools that are appropriate for the
diameter of the cable to be connected.
4.3 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) 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 12.
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,
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. At this time,
handle the wiring port in accordance with the JIS
C0920 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.
