WEG VBWC Series Installation,Operation And Maintenance Instruction page 7

WARNING!
1. Inspection and maintenance have to be performed by a qualified electrician.
Otherwise, there is the danger of malfunction, severe physical injury or electric shock.
2. When the circuit breaker is in service, don't open the front cover.
Otherwise, there is the danger of severe physical injury or electric shock.
3. Do not contact the internal structure when front cover is opened.
Otherwise, there is the danger of severe physical injury or electric shock.
4. Inspection and maintenance have to be performed only after shutting off the electric power and
discharging a charge current.
Otherwise, there is the danger of severe physical injury or electric shock.
5. Please tighten the bolts and screw with specified torque.
Otherwise, there is the danger of over-heat or fire.
6. After performing installation, maintenance or inspection, remove some foreign objects like tools, wires or bolts.
Otherwise, there is the danger of short circuit or fire.
7. Do not move a circuit breaker by holding main circuit terminals.
Otherwise, there is the danger of an electric accidents by temperature rise.
CAUTION!
1. Do not alter the control circuit at one's discretion.
Otherwise, there is the danger of malfunction or damage to products.
2. The circuit breakers must be kept in dry condition and keep away from the water.
Otherwise, there is the danger of deterioration of insulation.
3. This product must be stored at the place with no corrosive gas.
Otherwise, there is the danger of a product damage (discoloration, temperature rise or burns on contacts due to the
increased contact resistance).
4. When storing VCB for a long period of time, put dust cover on them to prevent dust from entering.
Otherwise, it may result in electrical accidents during the operation since dielectric strength gets reduced.
