The service life of the inverter depends on ambient
temperature. Ambient temperature should
be as low as
possible,
so thatthe allowable range may not beexceeded.
When housingthe inverter in an enclosure, this point
should beconsidered.

1. PRECAUTIONS
Use the Inverter wlthln the allowable ambient temperature range.
The service life of the inverter depends on ambient temperature.
Ambient temperature should be as low as possible, such that the
allowable range is not exceeded. Care should be taken for installation
direction and the environment.

Such installation might cause inverter trip or damage to the

If such a device is connected,
remove it.
The inverter output and input circuits (main circuits) contain high
frequency harmonics that may cause interference with
communication equipment
(AM radios). If so, use of a noise filter FR-BIF (only for input circuit) or a
line noise filter FR-BLF help to reduce the effects of noise.
Please contact your mitsubishi supplier for additional information.

1. These parametersrefer to maximum frequency when the Inverter is supplied.
When the inverter is supplied, the inverter output frequency is 60 Hz when the external frequency
reference signal is DC 5 V (1OV) or 20 mA. However, parameters (see below) that set the
maximum output frequency have a set value over
60 Hz.
‘ The parameter at shipment (60 Hz) that appears on pages 69,70 and 71 of this instruction
manual should be interpreted to
be the above.
Note:
To adjust the relationship between the frequency reference signal and output frequency, follow the
setting procedures describedon page
29 of this instruction manual.

2. Operation of the Parameter Unit When Using the Output shutoff Function
When using the parameter unit in the external signal operation mode, pressing the PU OP key on
the parameter unit
cannot select the PU operation mode if the output shutoff signal (MRS
terminal) and start signal (STF or STR terminal) are in the following conditions.
1. After the operator turned the output shutoff signal ON while the start signal was ON, the oper-
ator has turned off the start signal alone.

3. PreDaration before Operation
1.
Unpacking and Checking the Product
After unpackina the inverter, check the
rating plate at-the right side of the in-
verter to make sure that the model and
rating meet your order.
Also check that
the inverter has not been damaged.
