z Safety Notices
Be sure to read these Instructions and other associated documents accompanying the
product thoroughly to be familiarize yourself with the product handling, safety information, and
all other precautions before mounting, using, servicing, or inspecting the product. In these
Instructions, safety notices are divided into "Warning" and "Caution" according to the hazard
level:
: A warning notice with this symbol indicates that neglecting the suggested
procedure or practice could result in lethal or serious personal injury.
: A caution notice with this symbol indicates that neglecting the suggested
procedure or practice could result in moderate or slight personal injury and/or property damage.
Note that failing to observe notices could result in serious results in some cases.
Because safety notices contain important information, be sure to read and observe them.
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.
OFF
Mounting Precautions
(For detailed mounting dimensions, refer to the TemBreak2 catalogue.)
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.
Caution
Handling Precautions
Never touch terminals. Otherwise, electric shock may result.
Warning
When the breaker trips open automatically, remove the cause, then return the
handle to the |(ON)position. Should a fault be interrupted, the breaker must be
inspected. Otherwise, a fire may result.
Caution
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
after conductor connection, do not apply 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 short-
circuit.
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
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.
