(cid:1) Do not touch the live part in use;
(cid:1) Ensure the product is de-energized during maintenance and repair;
(cid:1) Do not conduct the product test using the short-circuit method.
Attention:
(cid:1) The installation, maintenance and service shall be performed by a professional;
(cid:1) Because all features of the product have been set in the factory, do not dismantle the product or adjust the
product without permission during use;
(cid:1) In order to prevent short circuit between phases, the exposed lead of the terminal or the copper busbar shall
be insulated.
(cid:1) To test the insulation resistance or power frequency withstand voltage, the electronic components between
the current circuit shall be disconnected, to prevent damage to the product performance;
(cid:1) To purchase accessories, please select the supporting accessories provided by our company to ensure good
quality. Our company will not bear any bad consequence due to the use of the other company’s parts;
(cid:1) For the product with an under-voltage release, the rated voltage must be applied onto the under-voltage
release before power-on.
(cid:1) If found damage or abnormal sound when unpacking, stop the product immediately and contact the supplier.
(cid:1) When scrapping the product, the proper product waste disposal procedure is required. Thanks for your
cooperation.Understanding of CDM1 Series Moulded Case Circuit Breaker
