2.1 Quick start-up

2.1.1 Unpacking inspection
Check as follows after receiving products:
1. Check whether the packing box is damaged or dampened. If yes, contact local
dealers or UNITRONICS offices.
2. Check the model identifier on the exterior surface of the packing box is consistent
with the purchased model. If no, contact local dealers or UNITRONICS offices.
3. Check whether the interior surface of packing box is abnormal, for example, in wet
condition, or whether the enclosure of the inverter is damaged or cracked. If yes,
contact local dealers or UNITRONICS offices.
4. Check whether the name plate of the inverter is consistent with the model identifier
on the exterior surface of the packing box. If no, contact local dealers or
UNITRONICS offices.
5. Check whether the accessories (including user's manual and control keypad)
inside the packing box are complete. If no, contact local dealers or UNITRONICS
offices.
2.1.2 Application confirmation
Check the machine before beginning to use the inverter:
1. Check the load type to verify that there is no overload of the inverter during work
and check whether the power degree of the inverter needs to be modified.
2. Check that the actual current of the motor is less than the rated current of the
inverter.
3. Check that the control accuracy of the load is the same of the inverter.
4. Check that the incoming supply voltage is correspondent to the rated voltage of the
inverter.
2.1.3 Environment
Check as follows before the actual installation and usage:
1. Check that the ambient temperature of the inverter is below 104° F (40° C). If
exceeds, derate 1% for every additional 1.8° F (1° C). Additionally, the inverter can not
be used if the ambient temperature is above 122° F (50° C).
Note: For the cabinet inverter, the ambient temperature means the air temperature
inside the cabinet.
2. Check that the ambient temperature of the inverter in actual usage is above 14° F
(-10° C). If no, add heating facilities.
