Warning ●Never touch terminals. Otherwise, electric shock may result.
Caution ●Electrical work should only be undertaken by suitably qualified persons. ●Do not place the product in an area that is subject to high temperature, high humidity, excessive dusty air, corrosive gas, strong vibration and shock, or other unusual conditions. Mounting in such areas could cause a fire or malfunction. ●Be careful to prevent foreign objects (debris, concrete powder, iron powder, etc.) and rainwater from entering product. These materials inside the product could cause a fire or malfunction. ●Prior to commencing any work on the product, open an upstream circuit breaker or isolator to ensure that no voltage is applied to the product. Otherwise, electrical shock may result. ●For 4-pole breakers, be sure to connect a neutral conductor to the N pole. Otherwise, an over-current may hinder the product from tripping, thus resulting in a fire. ●When connecting cable or busbar to the product, tighten terminal screws to the torque specified in this manual. Otherwise, a fire could result. ●Even when tightening the terminal screws and insulating tubes interpole after conductor connection, do not apply or barriers insulating tape excessive force to the terminals. Otherwise, a fire may result. ●For front-connected breakers, Insulate all bare conductors of the line side until the breaker end. If interpole barriers are packed, be sure to use the barriers; moreover, insulate all bare conductors by insulating tape or the like so that the tape overlaps with the barriers. Insufficient insulation may result in shortcircuit. ●Do not block the arc gas vents of the product to ensure adequate arc space. Blocking these vents could result in failure of circuit interruption.

■Maintenance Precautions
Caution ●Service and/or inspection of the product must be done by persons having expert knowledge. ●Before servicing or inspecting the product, open an upstream circuit breaker or the like to isolate all sources of power. Otherwise, electric shock may result. ●Regularly check that the breaker terminal screws are tightened to torque values shown within this manual, failure to do so may result in fire.

■Other Precautions ・Do not carry this product by accessory leads, as this may cause damage to the product. ・Unauthorised opening of the breaker cover will invalidate product warranty. ・When installing the product, use wires or conductors, the cross sectional areas of which accommodate the rated current of the product. Using wires or conductors with inadequate cross sectional areas may cause false tripping and overheat.
