4.4.2 General Precautions
Observe the following when wiring ;
(1) Do not connect cables outside when it is raining, to ensure insulation
within the terminal box of the meter tube and to prevent failure due to
moisture.
(2) Power cables and signal wire ends are to be provided with round crimp-
on terminal.
(3) Power cables and output signal cables must be routed in steel conduit
tubes separately.(except 4-core DC cable wiring)
(4) When waterproof glands, union equipped waterproof glands are used,
the glands must be properly tightened to keep the box watertight.
(5) Please install a external switch or circuit breaker as a means of power
off (capacitance:15A, conform to IEC 947-1 and IEC 947-3). The
preferable location is either near the instrument or other places to easy
operation. Furthermore, please indicate “power off equipment” on the
those external switch or circuit breaker.
(6) Please be sure to fully tighten the covers before the power is turned on.

(8) In case of DC Power Supply, a plug is attached. When 4-core cable is
used, please put that plug into unused electrical connection port.
