This instrument is of watertight construction as stipulated in JIS C0920 (Tests to prove

or waterproof gland with union) or a plastic gland attached, only in cases where an
optional specification is selected for the wiring port.

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 men-
tioned above. Do not remove the cap from the unused wiring port.

confirming that the cable is held firmly in place.
