Items to be practiced without fail for safety For correct operation, please go over this paper “Items to be practiced without fail for safety” beforehand. ● Essential items to ensure safety are stated here. Be sure to follow the cautionary instructions given below. ● The manufacturers assembling their products using this breaker are requested to convey the require- ments stated in this section “Items to be practiced without fail for safety” to the end users. ● The marks used respectively mean the following. Wrong handling can cause dangerous situation in which possibility of fatal accidents or serious injuries is assumed. Wrong handling can cause dangerous situation in which possibility of signifi- cant or minor injuries or only impersonal damages is assumed. Warning for possible electrification under certain conditions. Warning for possible outbreak of a fire under certain conditions. This means prohibition. Never ignore this indication. Be sure to follow these instructions without fail. 1.1 Cautionary instructions for operation DANGER CAUTION ● Don’t touch the terminal. Electrification can result. ● The earth leakage circuit breaker is so composed to operate when differential current be- tween going and returning reaches certain level, and no leakage is detected in the case as illustrated below. Never touch, therefore, the uncovered charged parts, two places at a time, and the power source side of the earth leakage circuit breaker. The circuit breaker doesn’t operate at the electrification. 1 DANGER Line side Load side Earth leakage circuit breaker Earth leakage circuit breaker Going current Going current Return current Return current [When uncovered charged parts are touched at two places] [When the power source side of the breaker is touched] ON ON
