Safety and Precautions MD280/MD280N User Manual
1.1.4 Before Power-on:
Caution
z Please confirm whether the power voltage class is consistent
with the rated voltage of the inverter and whether the I/O cable
connecting positions are correct, and check whether the external
circuit is short circuited and whether the connecting line is firm.
Otherwise it may damage the inverter.The cover must be well
closed prior to the inverter power-on. Otherwise electric shock
may be caused.
z The inverter is free from dielectric test because this test is
performed prior to the delivery. Otherwise accident may occur.
Danger
z The cover must be well closed prior to the inverter power-on.
Otherwise electric shock may be caused!
z Whether all the external fittings are connected correctly in
accordance with the circuit provided in this manual. Otherwise
accident may occur.
1.1.5 Upon Power-on
Danger
z Do not open the cover of the inverter upon power-on.
Otherwise there will be danger of electric shock!
z Do not touch the inverter and its surrounding circuit with wet
hand. Otherwise there will be danger of electric shock.
z Do not touch the inverter terminals (including control terminal).
Otherwise there will be danger of electric shock.
z At power-on, the inverter will perform the security check of the
external heavy-current circuit automatically. Thus, at this time
please do not touch the terminals U, V and W, or the terminals of
motor, otherwise there will be danger of electric shock.
