AttentIon!
Ensure that the screws of the terminals are tightened as per the torque
recommended in this manual. The screws and their tightening must
be checked
periodically, always with the circuits de-energized and
grounded.
Do not install the circuit breaker in dirty places at high temperatures,
with humidity, dust, corrosive gases, vibration or blows. The non-
observance of this recommendation can result in the malfunctioning of
the circuit breaker.
Whenever the circuit breaker is turned off by the action of the protection
unit, eliminate the cause of the failure before turning the circuit breaker
on again.
Only use the circuit breaker in circuits of 50Hz or 60Hz, paying attention
to the corresponding model of the protection unit.
CAutIon!
receipt
Execute the visual inspection immediately after receiving the circuit breaker,
and even before removing it from the pallet. If there is any sign of damage
or flaws caused by the transportation, inform the carrier and WEG directly.
transportation
Maintain the circuit breaker attached to the pallet and transport the unit
using a trolley or forklift.
Observe the following additional recommendations: - Always maintain the
pallet horizontal;
- Ensure that the load is balanced on the forks of the forklift;
- Attach the pallet to the forks so that it does not move or fall during the
transportation;
- Transport the unit at a low speed, without abrupt movements, avoiding
collisions with other structures, equipment or people;
- Only raise the unit to the extent required to pass over obstacles on the
floor, and never above people.
Handling / Movement
Removable hooks are supplied with each circuit breaker so that it is
removed from the pallet or extraction car, suspended by a crane. This is
the only method recommended for moving the circuit breaker. Be careful
not to damage the equipment if using other methods. Further details can
be found on page 22.
Other important recommendations:
- Do not put cords or cables through the suspension eyelets. Always use
safety hooks with a lock;
- The suspension cables must not be less than 45º from the horizontal.
Storage
If it is necessary to store the circuit breaker before installing it, maintain it in
its original packaging, in a clean, dry, ventilated and heated place to avoid
condensation. As with any other electrical equipment, protect it from dust
and humidity. Do not store the circuit breaker in an uncovered place or
exposed to bad weather.
