1.1 NOTES FOR OPERATION
Before wiring
●
Specification of applying power supply shall correspond to input voltage of the
inverter.
DANGER
●
Main circuit terminals must be correct, L1/R, L2/ S and L3/ T is input terminals and it’s
forbidden to use mixing with U/T1, V/T2 and W/T3. Failure to observe this may cause
the inverter damaged.
CAUTION
●
When delivering the inverter, do not take the cover directly. Take the air fan seat to
prevent the cover got off. Inverters getting off which may cause damage to personal
or machine shall be avoided.
●
Install the inverter on metal or other non-inflammable materials. Do not fix it on
inflammable materials which may cause a fire hazard.
●
In case of several inverters are installed together in one control panel, a fan shall be
prepared to make sure temperature lower than 50
℃
, thus over
-heating or a fire
hazard shall be avoided.
●
Make sure applied power supply comply with label showed on the right of the
machine. Failure to observe this may cause action failure.
During operation
DANGER
Never put in or take off the motor during operation, otherwise over-current even over
burning the main circuit of the inverter may happen.
When auto-restart function is set, do not approach the machine since motor can be
reset suddenly after being stopped.
The function set can make the stop key invalid, which is different from the emergency
stop key. Please pay attention to it.
