1. SAFETY INSTRUCTIONS
1.1 Notes for Operation
Before wiring
CAUTION
Specification of applying power supply shall correspond to input voltage of the inverter.
DANGER
Main circuit terminals must be correct, R/L1, S/L2 and T/L3 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 40
℃
, thus over-heating or a fire hazard shall be avoided.
Operator shall be dismantled or refitted after power supply is off. Fixed operator shall be processed as
diagram shows to prevent operator fault or no display.
CAUTION
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.
Do not remove the cover while current is flowing. Failure to observe this may result in electrical shock to
personnel.
When auto-restart function is set, do not approach the machine since motor can be reset suddenly after being
stopped.
Since STOP button can be selected by function set, which is different from usage of emergency stop/on
switch, attention shall be given to the usage.
