PRECAUTIONS

Follow these precautions to ensure safe operation

and to obtain the full benefits of the various

functions.

Preliminary Check

Before using the device the first time, verify that it operates normally

to ensure that the no damage occurred during storage or shipping. If

you find any damage, contact your dealer.

DANGER

• To avoid short circuits and potentially life-

threatening hazards, never attach the GCP-530 or

GCP-1030 to a circuit that operates at more than

300V, or over bare conductors.

• When conductors being measured carry in excess

of the safe voltage level (SELV-E) and not more

than 300 V, to prevent short circuits and electric

shock while the core section is open, make sure

that conductors to be measured are insulated with

material conforming to

(1) Measurement CategoryⅠ,

(2) Basic Insulation Requirements for Working

Voltages of 300 V, and

(3) Pollution Degree 2.

For safeties sake, never use this sensor on bare

conductors. The core and shield case are not

insulated.
